The Intergovernmental Oceanographic Commission (IOC) at the 17th IOC Assembly held in 1993 endorsed the Global Oceanographic Data Archaeology and Rescue (GODAR) project which has resulted in the rescue of vast amount of historical ocean data. These data are included in WOD13. Special thanks to Dr. Reiner Schlitzer from the Alfred Wegener Institute in Germany, for the development and continuous support of the Ocean Data View software and for allowing us to make this software available as part of WOD13. Thanks to the outstanding help from Carla Coleman and Alexandra Grodsky. We were able to improve on the quality of the data and metadata through their thoughtful examination of problems associated with doubtful or incomplete metadata from individual cruises, and their search on the Internet for missing information. In addition, they were part of the team rescuing data through manuscript digitization. The OCL acknowledges the help received over the years from many of our colleagues in the other divisions at NOAA/NODC: Tom Ryan and Brenda Humphries (for their assistance with all the code lists and accessions), Charles Sun, Norman Hall, and Melanie Hamilton (GTSPP data), Andy Allegra (reviewed web pages), John Relph (reviewed web pages and security). We also thank our NODC colleagues Charlotte Sazama and Igor Smolyar (assistance in locating data for rescue in the World Data Center for Oceanography, Silver Spring archives), the NODC Communications and Information Technology teams. The OCL also expresses gratitude to all users of previous World Ocean Database series who have provided helpful comments and suggestions for improvement of this product. All errors that may remain in the World Ocean Database 2013 are entirely ours. World Ocean Database 2013 would not be possible without the tireless efforts of thousands of sea-going oceanographers, technicians, data analysts, and scientists who collected and submitted data to the National Oceanographic Data Center and the World Data Center for Oceanography, Silver Spring. Our most sincere gratitude extends to all of them. The IOC and the International Council of Science (ICSU) World Data Center for Oceanography have played major roles in facilitating the international exchange of oceanographic data. We acknowledge these institutions and their staff for this contribution. I. INTRODUCTION A. OVERVIEW World Ocean Database 2013 (WOD13) is a scientifically quality-controlled database of selected historical in-situ surface and subsurface oceanographic measurements produced by the Ocean Climate Laboratory (OCL) at the National Oceanographic Data Center (NODC), Silver Spring, Maryland, USA. WOD13 updates and expands on an earlier version of our product, World Ocean Database 2009 (WOD09) by adding additional data and also increasing the number of standard levels and depths from 40 to 137 (see Table 14 for the standard depths). WOD13 provides quality-controlled data to calculate climatologies of temperature, salinity, oxygen, phosphate, silicate, and nitrate. These climatologies are used to produce the World Ocean Atlas 2013 (WOA13). The variables for which climatologies were calculated have full quality control, except for the oxygen and chlorophyll data from the Conductivity-Temperature-Depth (CTD) probes and Undulating Oceanographic Recorder (UOR) probes. These data and data for other measured variables have a more limited set of quality control. More detailed information is provided in Section III, Quality Control Procedures. In addition to quality control performed during calculation of WOA13 climatologies, quality control performed by the data submitters is included as originators’ flags when available. The WOA13 climatologies are calculated on standard levels. Since originators’ data are sampled on various observed levels, the measurements in the profiles are interpolated to the appropriate standard levels. Both the original measurements (observed level data) and the interpolated measurements (standard level data) are available in WOD13 and each has its own set of quality control flags. No data are removed from WOD13 if they fail WOD quality control checks; however, that fail objective and subjective tests are marked with quality control flags. Data are provided compressed in our native World Ocean Database (WOD) format. The data are stored in 11 datasets, each one representing a group of similar oceanographic probes: Ocean Station Data – OSD; High-resolution Conductivity-Temperature-Depth – CTD; Mechanical/Digital/Micro Bathythermograph – MBT; Expendable Bathythermograph – XBT; Surface – SUR; Autonomous Pinniped Bathythermograph – APB; Moored Buoy – MRB; Profiling Float – PFL; Drifting Buoy – DRB; Undulating Oceanographic Recorder – UOR; and Glider – GLD. In the remainder of this document, the following terms OSD, CTD, MBT, XBT, SUR, APB, MRB, PFL, DRB, UOR, and GLD are used. More information can be found in the Datasets Section and the Glossary. Over the past several years, a substantial number of datasets received at the NODC/World Data Center for Oceanography, Silver Spring (WDC) have been received as a result of projects such as the Intergovernmental Oceanographic Commission (IOC)/NODC Global Oceanographic Data Archaeology and Rescue project (GODAR) (Levitus et al., 1994, Levitus et al., 1998, Levitus et al., 2005), NODC Global Ocean Database project, IOC World Ocean Database project, Global Temperature-Salinity Profile Program (GTSPP), World Ocean Circulation Experiment (WOCE), Joint Global Ocean Flux Studies (JGOFS), Ocean Margin Experiment (OMEX), and many others. The numbers in Table 1 show the increase in data holding from 1982 to 2013. A more detailed description of data in the WOD13 can be found in Boyer et al. (2013). As Table 1 shows, the data holdings in the database have increased greatly since 1974. The OCL has attempted to ensure that the conversion of data from originator to WOD format was accurate, that duplicates were removed, and that “unrepresentative” data were flagged during the quality control process. This last task is an ongoing effort. Every effort was made to identify and correct errors in the database. As scientists and data managers utilize the WOD13, and additional errors are identified, they will be corrected. Some data flagged as “unrepresentative” may not deserve this designation and therefore could be reassessed. Table 1. Comparison of the amount of data in WOD13 with previous versions of WOD

1 Based on statistics from Climatological Atlas of the World Ocean (1982). 2 Based on NODC Temperature Profile CD-ROM. 3 WOD13 OSD dataset includes data from 174,777 low-resolution CTD casts and 1,708 low-resolution XCTD casts. 4 WOD13 CTD dataset includes data from 8,821 high-resolution XCTD casts. 5 WOD13 MBT dataset includes data from 79,500 DBT profiles and 5,659 Micro-BT profiles. 6 Surface data are represented differently from profile data in the database – all observations in a single cruise have been combined into one “cast” with zero depth, value(s) of variable(s) measured, latitude, longitude, and Julian year-day to identify data and position of individual observations. The OCL is actively seeking feedback from data contributers/users in order to improve various aspects of quality control, and in particular to identify questionable data and properly flag them, as well as to remove flags from data that have been erroneously flagged. We encourage data users to provide their comments and feedback through our E-mail address at: OCL.help@noaa.gov. As we receive input from users, corrections to the database will be implemented and amended data will be placed online on a monthly basis. Monthly updates are available on the NODC website. Should any errors be found, either in the data, its metadata, or in the flags assigned to the data, please contact the OCL at OCL.help@noaa.gov and these problems will be addressed. The OCL is committed to providing the U.S. and international scientific community with oceanographic data of the highest quality and will continue to pursue this goal. As part of this WOD13 release there are several software utilities included that can be used as examples of how to read the data and output them into different formats; these utilities continue to be improved. Any comments and suggestions for additional software utilities that could improve the convenience of use of WOD13 and lead to an increase in the number of users who can benefit from this product would be appreciated. Updates will be posted on the NODC website. B. DATA SOURCES Data submitted to, or obtained by, NODC as of January 23, 2013 which contain subsurface measurements of one or more of the variables listed in Table 3 or plankton measurements were potential data sources for WOD13. Due to lack of time, not all submitted data were converted to a uniform format and quality controlled in time for inclusion in WOD13. All datasets found in WOD13 can be found in their original submitted form at NODC and are accessible, using the NODC accession number, through the NODC Ocean Archive System. In addition to the subsurface data, specific surface-only datasets submitted to NODC were included. These surface datasets were selected because they filled a time period where there are little subsurface data for measured variables, or contained measured variables of special interest. Many of the datasets included in WOD13 were gathered as a result of the IOC/IODE GODAR project, the NODC Global Ocean Database project, and the IOC World Ocean Database project. A list of the project names and codes are available in s_2_project.pdf in the WOD13 Code Tables. C. DEFINITIONS A few terms which are important for understanding the data structure of WOD13 are: dataset, profile, cast, station, cruise, and accession number. Please refer to the Glossary for a more descriptive definition of these and other terms. WOD13 Citation The WOD13 should be cited as follows: Boyer, T. P., J. I. Antonov , O. K. Baranova, C.

1. Ocean Station Data (OSD) Historically, Ocean Station Data (OSD) referred to measurements made from a stationary research ship using reversing thermometers to measure temperature and making measurements of other variables such as salinity, oxygen, nutrients, chlorophyll, etc. on seawater samples gathered using special bottles. The OSD dataset includes bottle data, low-resolution Conductivity-Temperature-Depth (CTD) data, Salinity- Temperature- Depth (STD), some surface-only data with specific characteristics, some low-resolution Expendable XCTDs, and plankton taxonomic and biomass measurements. 3. Mechanical/Digital/Micro Bathythermograph (MBT) Data The MBT instrument was developed in its modern form around 1938 (Spilhaus, 1938). The instrument provides estimates of temperature as a function of depth in the upper water column. The MBT dataset contains data on water temperature profiles obtained from MBTs, Digital Bathythermograph (DBT) and Micro Bathythermograph (micro BT) instruments. 4. Expendable Bathythermograph (XBT) Data The XBT was first deployed around 1966 and replaced the MBT in most measurement programs. This electronic instrument has a thermistor which measures temperature vs. depth. Depth is calculated using the elapsed time of its free descent through the water column and fall-rate equation. (See Section IV for information on XBT fall-rate error.) 5. Surface (SUR) Only Data The SUR dataset contains data collected by any in-situ means from the surface of the ocean. The majority of the SUR observations were performed along ship routes in the Atlantic and Pacific oceans. In the SUR dataset each cruise is stored in the same form as a cast for other datasets. Each measurement has an associated latitude, longitude, and Julian year-day. 6. Autonomous Pinniped (APB) Data The APB dataset contains in-situ temperature data from time-temperature-depth recorders (TTDR) and temperature and salinity data from CTD sensors manually attached to marine mammals such as northern elephant seals (Mirounga angustirostris). 7. Moored Buoy (MRB) Data The MRB dataset contains temperature and salinity measurements collected from moored buoys located in the Tropical Pacific, tropical Atlantic, Baltic and North Seas, and area around Japan. These include the major ongoing Equatorial buoy arrays, TAO/TRITON, PIRATA, and RAMA. 8. Profiling Float (PFL) Data The PFL dataset contains temperature and salinity data collected from drifting profiling floats such as Profiling Autonomous Lagrangian Circulation Explorer (P-ALACE), PROVOR (free-drifting hydrographic profiler), SOLO (Sounding Oceanographic Lagrangian Observer), and APEX (Autonomous Profiling Explorer). The main source of the PFL data in WOD13 is the Argo project. 9. Drifting Buoy (DRB) Data The DRB dataset contains data collected from surface drifting buoys and drifting floats with subsurface thermister chains. The major sources of this data include the GTSPP project and Arctic buoy projects. 10. Undulating Oceanographic Recorder (UOR) The UOR dataset contains data collected from a Conductivity-Temperature-Depth probe mounted on a towed undulating vehicle. A description of the different types of UOR vehicles used for acquiring the data included in the WOD13 can be found in Appendix 2.21. 11. Glider (GLD) Data The GLD dataset contains data collected from reusable autonomous underwater vehicles (AUV) designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtoothed trajectory through the water. E. CAST DESCRIPTION In WOD13, a cast is comprised of as many as seven parts with the first five devoted to metadata holding: (1) Primary Header: Information vital to the identification of an individual cast, such as date, time, location, ISO country code, cruise code, and a unique cast number. (2) Secondary Header: Information such as meteorological data, sea floor depth, instrument, ship (platform), institute, and project. (3) Variable-specific secondary header: Information specific to each individual measured variable such as originator’s units, scales, and methods. (4) Character Data: Originator’s cruise codes, originator’s cast codes, and Principal Investigator’s code. (5) Biological Header: Information necessary to understand how biological data were sampled. “Biological” data are defined as plankton biomass (weights or volumes) and taxa-specific observations. (6) Taxa-specific and Biomass Data: Plankton weights, volumes, and/or concentrations, for an entire sample (biomass) or for individual groups of organisms (taxa-specific). (7) Measured Variables: Temperature, salinity, oxygen, phosphate, silicate, nitrate, pH, chlorophyll, alkalinity, partial pressure of carbon dioxide (pCO₂), dissolved inorganic carbon (DIC or TCO₂) tracers, and pressure data vs. depth. In addition, the SUR, APB, and UOR datasets contain latitude, longitude, and Julian year-day with each set of measurements. 1. Primary Header The primary header contains information about the number of bytes in the cast, a unique number which identifies each cast, the ISO country code (see code list in Appendix 1), a cruise number, date, time, position, and the number and type of variables in the cast. Please note that some data have been submitted with a day of zero (0) and we have kept these in the database as such. Time and location are all written in the same format: a) number of significant digits b) total digits c) precision of measurement d) data value Total digits will be one more than significant digits if the value is a negative number. Total digits will also be different than significant digits if a value has been converted or identified as a trace value. The station type identifies whether the stored data are collected at observed depth levels (0) or interpolated to standard levels (1). The number and type of variables identifies the depth-dependent variables in a cast. Depth-dependent variables are listed in Table 3 with their numerical identification codes. 2. Secondary Header The secondary header contains metadata (information about the data) and meteorological information associated with each cast. Table 4 lists the different types of secondary header data included for each cast, when such information is available. Many of the meteorological variables have World Meteorological Organization (WMO) or NODC code tables associated with them. These code tables are grouped together in Appendix 2. The complete listings of accession numbers (secondary header 1), project codes (secondary header 2), platform codes (secondary header 3), and institution codes (secondary header 4) are quite large and therefore are placed in individual files. All files can be found on the NODC website in the WOD code tables section. The WOD secondary header information is always in numeric format. A description of all WOD second headers is shown below.

Below is an explanation of the variable-specific secondary header codes listed in Table 5: • Code 1 NODC accession number: unique number assigned by NODC to each batch of data received (file: v_1_accession.pdf). Sometimes the variables for a cast are received at different times or from different sources and therefore may have different accession numbers. We have attempted to merge these casts together and kept the source information intact; • Code 2 Project: identifies the research project associated with the data collection. See file: v_2_project.pdf for a list of projects in WOD13; • Code 3 Scale: The units for temperature and salinity are based on the internationally agreed referenced measurement standards (i.e. ITS Temperature Scale, Practical Salinity Scale, and pH scales). Table 3 provides the detailed list of variables and units. Appendix 3.1 provides the list of scale codes. • Code 4 Institution: identifies institution associated with the investigator who sampled the specific variable (file: v_4_institute.pdf); • Code 5 Instrument: Appendix 3.2 provides a list of instrument used, also available in file v_5_instrument.pdf; • Code 6 Methods: Appendix 3.3 lists the methods associated with each variable measured. This list represents the methods reported with the data submitted and is not a comprehensive list of variable methods. Also available in file: v_6_measure_method.pdf; • Code 8 Originator’s units: Appendix 3.4 identifies the submitter’s original units. Also listed in file: v_8_orig_units.pdf; • Code 10 Equilibrator type: describes the design of the instrument used for equilibrating seawater with air in preparation for measuring CO2 concentrations (Appendix 3.5); • Code 11 Filter type and size (Appendix 3.6); • Code 12 Incubation time: 25 is dawn to noon, 26 is noon to dusk; otherwise, value is in hours (Appendix 3.7); • Code 13 CO$_2$ sea warming: temperature change in transporting water from the sea surface to the CO$_2$ analysis site; • Code 15 Analysis temperature: temperature of seawater at the time of CO$_2$ analysis; • Code 16 Uncalibrated: set to 1 if instrument is uncalibrated; • Code 17 Contains nitrite: set to 1 if nitrate value is actually nitrate+nitrite; • Code 18 Normal Standard Seawater batch: the code gives the IAPSO normal standard seawater batch number, P-Series, *i.e.* code 78 means normal standard seawater batch P78. • Code 19 Adjustment: this is an adjustment (correction) value made to Argo profiling floats. The adjustment is a real value (*i.e.* decimal number) and is the mean difference between original (real-time) and adjusted (delayed-mode) profile of temperature, salinity, oxygen, or pressure for all values below 500 meters depth. If a profile has an adjustment value (even if this value is 0.0, it indicates that the profile has gone through additional quality control by the Argo project and is considered either adjusted real-time or delayed-mode data. **4. Character Data and Principal Investigator Code** Character data are used to report the originator’s cruise identification and the originator’s station identification, if provided, which could be in alphanumeric format. If the originator’s code is purely numeric, it will be found in second header code 7. The Principal Investigator (PI) is also identified by numeric code and by variable code. The PI is the person (or persons), responsible for data collection and this information is included whenever available. A list of the numeric codes associated with each PI can be found in the file: primary_investigator_list.pdf. For the purpose of assigning PI codes, plankton data are identified as variable 14 for all plankton, -5002 for zooplankton, and -5006 for phytoplankton. **5. Biological Header** The biological header section contains information on the sampling methods used for collecting taxonomic and biomass data. Table 6 lists the different types of biological header information included for each cast, if it was available. Similar to the secondary header information, some description is provided by code lists. All code tables are listed in Appendix 4 (the biological headers are listed in file Table 6). The “App” column indicates the Appendix of this document where the code list is found; the “ID” column represents the WOD code number assigned to each biological header entry. Table 6.

The following is a description of the biological header codes listed in Table 6: • Code 1 Water volume filtered: total volume of water filtered by the sampling gear, in m3; • Code 2 Sampling duration: time over which the sampling gear was towed, in minutes; • Code 3 Mesh size: pore size of the sampling device, in micrometers; • Code 4 Type of tow: towing method used (e.g., horizontal, vertical, oblique) – Appendix 4.1; • Code 5 Large removed volume: the minimum volume criteria for removing large plankters, in ml, see also code 12; • Code 6 Large plankters removed: if large plankters were specified as being removed (1) or not removed (2), this code is added. See codes 5 and 12 in Appendix 4.2; • Code 7 Gear code: type of gear used (e.g., plankton net, bottle, MOCNESS) – Appendix 4.3; • Code 8 Sampler volume: internal volume of the sampling gear (e.g., Niskin bottle), in liters; • Code 9 Net mouth area: mouth or opening area of the sampling gear, in m2. If mouth diameter was provided, area was calculated as: area = \( \pi \) (0.5 diameter)2; • Code 10 Preservative: type of preservative used to preserve the plankton sample (Appendix 4.4); • Code 11 Weight method: method used for weighing the plankton sample (Appendix 4.5); • Code 12 Large removed length: the minimum size/length criteria for removing large plankters, in cm, see also code 5; • Code 13 Count method: method used for counting the plankton sample (Appendix 4.6); • Code 14 Tow distance: distance over which sampling gear was towed, in meters; • Code 15 Average tow speed: average speed used to tow the sampling gear, in knots; • Code 16 Sampling start time: GMT; • Code 18 Flowmeter type: the brand and/or model of the flowmeter used (Appendix 4.3); • Code 19 Flowmeter calibration: the calibration frequency for the flowmeter (Appendix 4.7); • Code 20 Counting Institution: the Institution responsible for identifying and counting the taxa-specific sample (file: b_21_institutes.pdf; see institute code); • Code 21 Voucher Institution: the location (Institution) of the taxa-specific sample voucher (file: b_21_institutes.pdf; see institute code); • Code 22 Wire angle start: wire angle of the towing apparatus at sampling start, in degrees; • Code 23 Wire angle end: wire angle of the towing apparatus at sampling end, in degrees. • Code 24 Depth determination method: a code indicating that depth was calculated from wire angle and length or a PI-specific “target depth” (Appendix 4.8); • Code 25 Volume method: the method used for measuring the volume of the plankton sample (Appendix 4.9); • Code 30 Accession number for biology: NODC dataset identification for the biological component of the current cast (file: b_30_accession.pdf). 6. Taxa-specific and Biomass Data The typical plankton cast, as represented in WOD13, stores taxon specific and/or biomass data in individual sets of unique observations, called “Taxa-Record”. Each “Taxa-Record” contains a taxonomic description, depth range (the upper and lower depth) of observation, the original measurements (e.g., abundance, biomass or volume), and all provided qualifiers (e.g., lifestage, sex, size, etc.) required to represent that plankton observation. Each unique taxonomic description, depth range, or measurement has its own “Taxa-Record”. For example: • Biomass (displacement volume) measured from 0-100m, and 200-500m, will have two “Taxa-Records”, one for each depth range, • Biomass (displacement volume and wet weight) measured from 0-250m will have two “Taxa-Records”, one for each type of biomass measurement, • A taxa-specific measurement of a single species, counted at five bottle depths, will have five “Taxa-Records”, one for each depth, • A taxa-specific measurement of ten species, counted at five bottle depths, will have 50 “Taxa-Records”, five depths multiplied by ten species. Note that taxa with different taxonomic descriptors (e.g., life stage, sex code, etc.) are treated as different unique taxonomic descriptions, and are stored in different Taxa-Records. For example: Calanus eggs, Calanus juveniles, Calanus adults (male), and Calanus adults (female) would be stored as four separate observations, each with the same genus, but differing in their taxon life stage and/or taxon sex. Table 7 lists the different types of taxa-specific and biomass data fields for each Taxa-Record, if the information is available. Each cast can have multiple Taxa-Records, and each Taxa-Record can contain any of the fields in Table 7. Similar to the biological header information, much of the information is represented by codes. Code tables for these variables are listed in Appendices 3.4, 5.1 through 5.11, and 6. The “App” column indicates the Appendix where the code table is found; the “ID” column represents the code number assigned to each biomass and taxon-specific variable. “UNIT” refers to the originator’s units (code 20).

See Table 8 for a breakdown of these codes and complete numerically sorted taxonomic list available on-line (file t_1_taxa_list.txt); • Code 2 Upper depth: the shallowest depth of the sample, in meters; • Code 3 Lower depth: the deepest depth of the sample, in meters; • Code 4 Biomass value: contains biomass value measured, units are specified by the biomass variable code (Table 8 and Appendix 5.8); • Code 5 Taxon lifestage: a specific lifestage indicated for a taxonomic observation (*e.g.*, *Calanus finmarchicus*, nauplii) – Appendix 5.1; • Code 6 Taxon sex code: a specific sex indicated for a taxonomic observation (*e.g.*, • Code 7 Calanus finmarchicus, female) – Appendix 5.2; Taxon present: a non-numeric description of the relative abundance, presence indicator (e.g., “rare”, “common”, “dominant”) – Appendix 5.3; • Code 8 Taxon trophic mode: a specific trophic description for a taxonomic observation (e.g., autotrophic picoplankton) – Appendix 5.4; • Code 9 Taxon realm: a specific realm description for a taxonomic observation (e.g. bathypelagic fish) – Appendix 5.5; • Code 10 Taxon count: the number of an individual taxon counted, in count per unit (as specified by code 20); • Code 11 Sample-specific sample volume: used only when each sample within a tow has a different sample volume (e.g., the different volumes filtered by each net of a MOCNESS net). If the value is >0, the units are “m^3 per UNIT”. If the value is <0, the units are “ml per UNIT”, where UNIT is specific by code 20; • Code 12 Taxon volume: the volume of an individual taxon counted. If the value is >0, the units are “ml per UNIT”. If the value is <0, the units are “nl per UNIT”, where UNIT is specific by code 20; • Code 13 Taxon wet weight: the wet weight of an individual taxon counted. If the value is >0, the units are “g per UNIT”. If the value is <0, the units are “mg per UNIT”, where UNIT is specified by code 20; • Code 14 Taxon dry weight: the dry weight of an individual taxon counted. If the value is >0, the units are “g per UNIT”. If the value is <0, the units are “mg per UNIT”, where UNIT is specific by code 20; • Code 15 Taxon ash-free dry weight: the ash-free dry weight of an individual taxon counted. If the value is >0, the units are “mg per UNIT”. If the value is <0, the units are “ng per UNIT”, where UNIT is specific by code 20; • Code 16 Taxon feature: a specific feature or shape indicated in a taxonomic observations (e.g., athecate Dinoflagellate) – Appendix 5.6; • Code 17 Taxon modifier: a specific taxonomic identity description for a taxonomic observation (e.g., Calanus spp., Ceratium sp. A, Ceratium sp. B, Ceratium spp., other) – Appendix 5.7; • Code 18 Minimum size range description: the smaller size range used in a taxonomic description. If the value is >0, the units are “mm”. If the value is <0, it is a code (-1 = small, -2 = medium, -3 = large, -4 = very small, as provided in the original taxonomic description (file t_18_size_min.pdf) – Appendix 5.8; • Code 19 Maximum size range description: the larger size range used in a taxonomic description, in mm (on-line file t_19_size_max.pdf) – Appendix 5.8; • Code 20 Originator’s Unit: additional unit identifier for biomass and taxa-specific measurements (Appendix 3.4); • Code 21 Taxon radius description: the radius (0.5 diameter) used in a taxonomic description, in μm; • Code 22 Taxon length description: the length or height used in a taxonomic description, in μm; • Code 23 Taxon width description: the width or shortest-dimension used in a taxonomic • Code 25 description, in μm; Taxon carbon content: the carbon content of the individual taxon counted. If the value is >0, the units are “g per UNIT”. If the value is <0, the units are “mg per UNIT”, where UNIT is specific by code 20; • Code 26 Count method: used only when multiple methods are used within a single measurement (e.g. to distinguish bacterial groups discerned and counted by different staining and/or fluorescent techniques within a single sample) – Appendix 5.9; • Code 27 Common Base-unit Value (CBV): a “per-unit-volume” common base-unit value calculated from original value using sampling metadata (e.g., towing distance, water volume filtered) – Appendix 5.10; • Code 28 CBV calculation method: method used for calculating the CBV – Appendix 5.11; • Code 30 Plankton Grouping Code (PGC): a Smart-Index (O’Brien 2007) indicates a plankton taxa’s membership in up to four tiered groups – Appendix 6. Scientific taxonomic names in the plankton description follow the Integrated Taxonomic Information System (ITIS) as an authority table, and are represented in WOD13 under the ITIS taxonomic serial number (on-line file t_1_taxa_list.pdf). This approach was not applied for all plankton descriptions. For example, non-scientific descriptions such as “gelatinous organisms”, combinations of multiple species in a single description, and “total haul biomass” measurements can not be represented using ITIS. Therefore, ancillary codes were developed to preserve these original descriptions. Table 8 provides a list of value ranges for all Variable number code values present in WOD13. WOD13 negative taxa codes follow those laid out for the COPEPOD database (O’Brien 2007).

In addition to the original plankton descriptions, each “Taxa-Record” also contains a supplemental WOD13 grouping index – Plankton Grouping Code (PGC) developed by O’Brien (2007), code 30. The PGC code follows the taxonomic hierarchy presented in The Five Kingdoms (Margulis & Schwartz 1998). It places each taxon into broader groups (e.g., “phytoplankton”, “diatoms”, “zooplankton”, “copepods”) which allows the WOD13 user access to hundreds of individual taxons by using a single PGC code. Appendix 6 lists the PGC groups and codes available in WOD13. Earlier versions of the World Ocean Database (2005, 2001) used a PGC precursor index called the Biological Grouping Code (O’Brien et al. 2001). The PGC combines the BGC’s separate “protist” grouping with the “phytoplankton” group. WOD13 has all BGC codes replaced with their corresponding PGC codes. PGC Example: Calanus finmarchicus The PGC is a 7-digit code divided into Major (e.g. Bacteria, Phytoplankton, Zooplankton), Minor (e.g. cyanobacteria, diatoms, crustaceans), and Focus Groups (e.g., copepods). For example, the copepod Calanus finmarchicus has a PGC code of “4212000”, specifying that it is in Major Group “4” (zooplankton), Minor Group “21” (crustaceans), and Focus Group “2000” (copepods). Using the PGC code requires the multiplication of the PGC code value, outlined in Table 9, to specify the exact grouping level desired (e.g., “all zooplankton”, “all crustaceans”, or “all copepods ”).
Desired Group PGC Value Multiply by Result PGC Equivalent (see Appendix 6)
MAJOR GROUP 4212000 4 zooplankton
4218000 10^{-6} 4 zooplankton
2160000 2 phytoplankton
MINOR GROUP 4212000 421 crustacean
4218000 10^{-4} 421 crustacean
2160000 216 diatoms
FOCUS GROUP 4212000 10^{-2} 42120 copepods
4218000 42180 euphausiidae
Table 9. Operational example of the Plankton Grouping Code Plankton numerical abundance and total biomass measurements are stored with the originator’s units in WOD13 (e.g., “number per m^3”, “count per m^2”, “count per haul”, “count per ml”, “displacement volume per haul”). To make comparison of measurements provided in different units easier, each numerical abundance or biomass measurement has been recalculated into a common unit named Common Base-unit Value (CBV), code 27. The CBV value has a quality control flag associated with it (see Table 12 for a definition of the flags). The calculation method used to create the CBV is stored in the CBV calculation method field, code 28, and detailed in Appendix 5.11. The CBV unit is dependent on the major taxonomic group of the measurement, as classified in the Plankton Grouping Code for that observation. For example, bacteria and phytoplankton counts are units of “count per ml”, whereas zooplankton and ichthyoplankton counts are in units of “count per m^3”. The CBV units for taxonomic counts and various biomass measurements are detailed in Appendix 5.10. 7. Measured Variables The number of variables, their type, as well as a quality control flag for each variable (if all values of that variable have been flagged for that cast) are identified in the primary header. Table 3 lists the variables and their identifying codes. Table 12 lists the types of quality flags assigned to each variable. Casts with data on pressure surfaces have their depths computed, so depth is always present and the pressure value is stored as a variable. Some data were submitted with both depth and pressure values in which case both are stored. Some casts may be reported on standard depth levels (see Table 14) such as most of the Japanese and Former Soviet Union (FSU) data. It is uncertain whether these data were originally measured at standard levels or interpolated to standard depth levels. The following three datasets are discussed in more detail since they include additional information so as to fit the WOD format. 7a. Surface-only Data (SUR) Surface-only data are treated differently than profile data. For such data, each cruise is presented as a single cast with depth, latitude, longitude, and Julian year-day associated with each set of measured values. The Julian year-day 0.00 is defined as time 0.00 on January 1st of the year of the first measurement in the cruise. For cases in which the cruise spans 2 calendar years, the year-day is consecutive. For example, if the first measurement was taken at time 0:00 on 31 Dec. 1965 (not a leap year), the year day for that observation is 365.00. If the last measurement on the same cruise was taken at time 12:00 on 1 January 1966, the year-day is 366.5. An example of data from a surface cast is shown below:

Note that the primary header information contains the same longitude, latitude and date/time information as the first observation in the listing. 7b. Autonomous Pinniped Data (APB) Autonomous Pinniped Data (APB) are the temperature (salinity) data recorded by temperature-depth recorders (TDRs) or conductivity-temperature-depth satellite relay data loggers (CTD-SRDLs) manually attached to large marine mammals (e.g. northern elephant seals). Depth and temperature (salinity) are recorded by the TDR or CTD-SRDL as the mammal ascends and descends through the water column while swimming. When the mammal returns to the surface, its position is transmitted to the ARGOS unit. During the seals multi-month migration, the seals dive continuously, night and day, capturing thousands of profiles along their migration route (e.g., Boehlert et al., 2001). 7c. Undulating Oceanographic Recorder (UOR) Undulating Oceanographic Recorder (UOR) is the generic name given to towed vehicles carrying measuring devices (usually CTDs, plankton recorders, transmissometers, etc.) which ascend and descend through the water column in a more or less regular pattern, giving a two-dimensional view of the water column along the towing path. UOR measurements are usually close together in time and space, and are continuous, from the near surface layer to a maximum depth of about 500 m. To fit this dataset into the WOD format, the undulations are broken into distinct up and down casts, and all the measurements between the breaks are averaged on a minimum pressure increment of 1.0 decibar. The latitude and longitude are also averaged for each measurement, as is the date/time (preserved as Julian year-day). This averaged metadata value is kept with each measurement of the oceanographic variables. The coordinates stored in the cast header is the position of the portion of the tow when the vehicle is at the exact middle of its ascent or descent (based on the averaged decibar increments). Some of the data received was already processed to some extent by originators and did not include latitude, longitude, or Julian year-day. A tow can be broken into either a few up or down segments or thousands of segments. The tow number (secondary header 5) along with the Segment Number (secondary header 93) can be used to follow the progression of a tow in time, as the segment numbers correspond to the sequence of up or down undulations. II. FILE STRUCTURE/FORMAT All files which contain observed and standard level data are written as a series of 80 character length ASCII records. A detailed record layout for the data can be found in Table 10 (primary header format; character data, secondary and biological header; and integrated, taxonomic and profile). There is a carriage return code after each 80 bytes (CR-LF). Each cast begins on a new line. Starting with WOD01, the first byte in a cast is a character which identifies the World Ocean Database version. If the first byte is character “C”, it refers to WOD13 format, a “B” refers to WOD09 or WOD05 format, and “A” refers to WOD01 format. If the first byte is numeric, it identifies WOD98. There is one format change between WOD09 and WOD13, and only for standard level data files. Since standard levels have changed for WOD13 compared to all previous releases, depths are now explicitly given for each depth level, rather than implicit as for previous WOD formats. Each section of a cast (e.g., primary header and variable-specific second header, character data, secondary header, biological header) begins with the number representing a total byte count for that section. If there are no data for that section, the byte count is zero. If there are data for that section which are of no interest to the user, the byte count can be used to skip over this sections. The header includes the ISO country code (see Appendix 1 for the complete list), cruise number, position, date, time, internal unique cast number, the number of observed or standard depth levels, an identifier for observed or standard level data, number of variables, variable codes, originator’s flag for observed level data only, and a flag if all of a variable’s data in that cast fails a quality control check (see Table 12 for a description of the flags). Appendix 8 shows sample data output from Cast 67064 (using the program wodFOR.f) This sample output contains temperature, salinity, oxygen, phosphate, silicate, and taxonomic / biomass data (“f” denotes the flag assigned to the variable and “o” denotes the originator’s quality flag); numbers in parenthesis represent the number of significant digits in the value; “VarFlag” identifies whole profile flags for each variable). For compactness, each variable is written as follows: STPVVVVVV[F][O], where: S = Number of significant digits in a value; T = Total number of digits in a value. This is usually the same as [S], but can vary in cases of negative numbers, converted values, and data in which the values are reported with more precision than an instrument is capable of recording; P = Precision of a variable (number of places to the right of the decimal point); V = The actual value. This is read in using [T] and [P]; F = WOD quality control flag; O = Originators flag. For example: A salinity value, written as [5533389100] means that S = 5, T = 5, P = 3. Using this information, there are five bytes in the salinity reading, with a precision of three, so V(sal) = 33.891, F = 0, O = 0. A missing value in this data format is always represented with an S = '-' (the minus character). That is, when the number of significant digits is read in, the character encountered will be a negative sign. This tells the user that no value was recorded and to skip to the next value. Table 10.1.

A. DESCRIPTION OF THE INTERNET PAGES AND FILES What follows are the Internet page names and the contents of each page: • WODselect – contains the online version of data retrieval; • WOD data - contains the geographically sorted and year sorted data; • WOD documentation - contains the documentation; • WOD codes tables - contains codes associated with the secondary header, variable specific header, biological header, and taxa data; • WOD utilities - contains the utilities necessary to convert files from DOS to UNIX format and to decompress the data; • WOD programs - contains sample FORTRAN and C programs for reading the data and allow the user to convert the data to the comma separated format so it can be read into Matlab (or any other tabular program); and • WOD masks – contains masks necessary for the WOD. 1. WODselect WODselect is a product offered for searching and retrieving WOD data. This is an online interface which allows a user to search the World Ocean Database using a variety of user-specified search criteria. The search criteria will provide a distribution map, cast, count, and the option for selecting output format of the data files (native or “.csv”). In this section the user builds a data retrieval request based on their choice of criteria such as geographic coordinates, observations datasets, dataset (e.g. OSD, CTD, XBT), measured variables (e.g. temperature, salinity, nutrients), biology (e.g. phytoplankton, zooplankton), deepest measurement, country, platform, project, institute, and data exclusion using WOD quality control flags. 2. WOD13 Data The directory WOD data contains links for the user to retrieve data sorted geographically or sorted by year (time). The geographically sorted data are organized by WMO 10-degree square. A world map with the WMO codes in each 10-degree square is provided in Appendix 7. Data chronologically sorted by year are available in the WOD13 Data directory. In both the geographically sorted and the year sorted data subdirectories the user has the option to retrieve data by observed (O) or standard (S) level and by dataset (see Table 2 for the complete list of datasets). For a tutorial on how to use the data (i.e. import) in ODV see Section V. 3. WOD13 Documentation The directory WOD documentation contains a copy of this document and other files necessary for accessing, reading, and using WOD13 data. All files are in PDF format. Files in the directory WOD documentation: WOD13 User’s Manual PDF version of this document; WOD13 Tutorial PDF tutorial describing how to access, read and use WOD13; WOD13 Introduction PDF describing in detailed all datasets available in WOD13. 4. WOD13 Code Tables The directory WOD code tables contain all files describing the metadata in secondary header, variable specific header, biological header, and taxa data. All code files except b_30_accession.pdf, s_1_accession.pdf, v_1_accession.pdf, s_2_project.pdf, v_2_project.pdf, b_20_institute.pdf, b_21_institute.pdf, s_4_institute.pdf, v_4_institute.pdf, s_3_platform.pdf, and t_1_taxa_list.txt are listed in the appendices of this document. All files in this directory are Portable Document Format (PDF) and Text (TXT) documents. File structure is as follows: • Secondary Header Files are prefixed with the letter “s” • Variable Secondary Header Files are prefixed with the letter “v” • Biological Header files have the prefix “b” • Taxonomic files have the prefix “t” • All other files are given their unique names (e.g. country_list.pdf, and primary_investigator_list.pdf) 5. WOD13 Utilities The WOD utilities directory contains the utilities necessary to convert files from DOS to UNIX format and to decompress the data. It contains two GZIP files needed for decompressing the WOD13 data. GZIP: There are two utilities used for decompressing the zipped data files. The first (gzip124.exe) is a self-extracting DOS executable and the second (gzip124.tar) is a tar'd file containing source code for UNIX users. a. Installing gzip For the First Time DOS Users: The file gzip124.exe is a self-extracting DOS executable. Copy gzip124.exe to your hard disk; preferably into a directory listed in your path. Run gzip124.exe and use the file gzip.exe to uncompress WOD13 data as described below. UNIX Users: Copy gzip124.tar to your UNIX system and run the following commands: tar xvf gzip124.tar These commands will create a directory named gzip124 which include the gzip source code and documentation on copyrights, compression methods, and how to compile and install the gzip code. The readme file contains instruction on how to execute gzip. b. Decompressing Data from WOD13 To decompress the WOD13 files, it is easier to copy the files to the hard disk. Use gzip to decompress selected files or a directory and all subdirectories with one command. gzip has a limited help menu accessible with the -h option (i.e., gzip -h) To decompress a single file: gzip -nd To decompress the contents of a directory and all subdirectories: gzip -dr If an older version of gzip is used, the -n option is required in order to preserve the correct file names. 6. WOD13 Programs The directory WOD programs contains sample programs, written in FORTRAN and C, for reading the data (wodFOR.f, wodC.c). Another FORTRAN program (wodASC.f) has an option to output the sample data in either tabular column or comma separated columns (also known as comma separated values, csv) format which can be read by MatLab, GRAPHER, or other graphical packages. The following are sample converters from the WOD format to other formats. readFOR.txt readme file describing wodFOR program wodFOR.f sample FORTRAN program for reading the data sampFOR.txt sample output data from wodFOR.f readASC.txt describes the use of wodASC program wodASC.f outputs a user-selected variable in either tabular- (columns) or comma-separated-values columns wodASC.exe executable for wodASC.f program sampASC.txt sample output data from wodASC.f wodSUR.f write the Surface format out into comma-separated-values (CSV) file wodSUF.exe executable for wodSUR program sampSUR.txt sample of output from wodSUR program Instructions from WOD to csv instructions to convert WOD format to ArcMap readable 'csv' format csvfromwod.c (β - version) C program to convert data from WOD format to ArcMap readable 'csv' format csvfromwod.exe executable for C program ArcGIS tutorial tutorial to convert 'csv' files in to shapefiles and upload it in ArcMap readC.txt describes the use of wodC program wodC.c sample C program for reading the data wodC.exe executable for C program for Microsoft Windows environment 7.

SYSTEM REQUIREMENTS The minimum hardware requirements for accessing data and information are: • Using the Ocean Data View 4.5.7 software has additional requirements, which are addressed at the ODV web site. III. QUALITY CONTROL PROCEDURES Data received by the National Oceanographic Data Center’s Ocean Climate Laboratory (NODC/OCL), through the Global Ocean Data Archeology and Rescue (GODAR) project, the Global Ocean Database project, the Global Temperature and Salinity Pilot Project (GTSPP), the US-NODC data archives, or other sources, are put through a set of quality control procedures to ensure that 1) the data are converted to the WOD format correctly, 2) the data format provided with the data is correct and the data have not been corrupted in transmission, 3) only one copy of data at each cast is retained in the WOD format, and 4) the data, as initially collected and processed, are of good quality. The OCL continues to quality control the data and requests input from the users as to possible problems identified when using the data. As these problems are corrected, the updated casts will be placed online and the changes documented. Some data are included in WOD13 even though all the quality control steps were not applied. These are pCO₂, DIC (or TCO₂), geochemical tracers, plankton (we are in the process of building up the database and have insufficient data to date), oxygen from PFL; (data not used in the objective analysis), chlorophyll from CTDs, and UORs. In addition, nitrite was excluded from the database since the data were not examined to ensure their quality. Air pressure, Julian year-day, latitude, and longitude, included as variables for the sole purpose of identifying the surface-only, APB and UOR data, were not quality controlled beyond basic range checks. The WOD includes quality control flags that are set during automatic and subjective quality control steps in the calculation of WOA09 climatologies. There are quality control flags with each measurement and for each profile. A complete list of WOD quality control flags and their definitions is provided in Table 12. In addition to the WOD quality control flags, there are quality control flags provided by data submittors (i.e., originator’s flags). The only datasets with included originator’s flags are those associated with the GTSPP, WOCE, CalCOFI (all data since August 1996), PMEL TAO and PIRATA data, Argo, OMEX, and GESECS projects, as well as some smaller datasets (Appendix 2.26 lists the originators flags and their associated project or accession number). The originator’s flags were included with the observed level data only. A. QUALITY CONTROL OF OBSERVED LEVEL DATA 1. Format conversion When data are received at the NODC/OCL, the first step, after assigning a NODC accession number, is to convert the data into the OCL internal format. Some of the checks during format conversion include calculation of the number of significant digits, identification of time zone used (GMT or local), and checking the consistency of the originator’s data format. Additionally, where originator’s data units differ from the standard WOD units, data are converted to the standard WOD units (Table 3). After conversion to WOD format, data are checked and compared with the original data for accuracy in the data conversion. If/when problems with data are noted, the data originator is contacted when possible 2. Check cast position/date/time Converted data are checked for metadata integrity - incorrect/missing latitudes, longitudes, time, and dates. Questionable values are compared with the original data to make sure that problems are not introduced during the conversion process. If the incorrect datum is found in the original data, the data submittor is notified of the error and a correction is requested when possible. 3. Assignment of cruise and cast numbers Once cast positions and dates are checked, unique cruise numbers are assigned. In some cases, data cannot be clearly identified as having been collected on a single cruise (e.g. data collected by a single ship over a prolonged period of time). In these cases, cruises are defined by OCL data scientists (if/when not provided on request by the data originator). A general definition is that a cruise is comprised of casts for which the time difference between any two casts is <20 days. This definition is a guideline, as some datasets necessitate a smaller break period, and others a longer period. Some data which have nonspecific platforms (e.g. airplane or ice-camp) are not amenable to this treatment. If no platform or primary investigator information is provided, a cruise number of zero (0) is assigned to denote the absence of cruise information. All submitted casts are assigned a sequential number which is unique to that cast. This unique cast number allows the OCL to identify and record any changes made to the cast, as well as cast deletion. Note, this internal unique cast number is not the originator’s cast number. The originator’s cast number is kept in its original form. 4. Speed check Following assignment of cruise numbers, the entire cruise is mapped out and the speed between casts is calculated. If the speed between adjoining casts is unrealistic, the date/time may be in error, the position may be wrong, or the cast may not belong to this cruise/platform. These problems, when encountered, are noted and the submittor contacted to decide on a course of action. Due to lack of time and resources, not every single cruise was checked and therefore some groupings of casts may not represent a cruise as defined here. 5. Duplicate cast checks Upon completion of these preliminary quality control checks, extensive duplicate checks are performed – first internal to the new dataset, and then the data is checked against the existing WOD databases. Duplicates are a continuous problem with any historical database. While exact duplicate profiles are easy to identify and remove, “near” duplicates are more difficult to detect. Such duplicates can result from receiving the same data from different sources, where key metadata variables such as latitude, longitude, or date/time were treated differently. As the procedures for identifying duplicate casts improve, more of these “near” duplicate casts continue to be identified and eliminated. Duplicate checks involve identifying casts with: • same position/date/time • position/date/time within some small offset • same originator’s cast numbers within a cruise • same profile data • same taxonomic data Below are the general types of duplicates which were found to occur: Identical or nearly identical profiles – two or more profiles which contain the same variable with identical values at each depth. Frequently, positions or times of such profiles may be slightly different (depending on the accuracy to which latitude/longitude/time were provided in the original data submissions). Sometimes larger differences in time (up to a one day offset) may also take place when time is provided in GMT in one dataset and in local time for the other. Identical casts – two or more casts from the same location, date and time, but with different variables or different values. When values are different, the casts may contain identical profiles that were handled differently by an intermediate data center or investigator (e.g. using different storage criteria with XBT’s or CTD’s, or interpolating the observed data to standard levels). When variables are different between two casts which are otherwise identical, this may be due to cases in which data were submitted separately. Therefore variables from these casts are combined (see Special Case: merging profiles below). Overlapping Cruises – two or more cruises with the same platform code that overlaps in their starting and ending dates. In most cases, the overlapping cruises are duplicated and have already been detected by the previous two checks. In others cases, the difference in positions is so great that the standard position check does not detect the duplicated casts (e.g. a missing “+/-” for latitude would give two casts (or set of casts), collected from the same platform with the same times and data values, in both the northern/southern or eastern/western hemispheres). When duplicates are found, the “better” cast is retained within the database, and the other cast is marked for removal. In general, the retaining (i.e. “better”) cast has more depth levels, additional variables, or data at a higher precision. Preference is given to the original observed level data over interpolated. As a rule, data obtained directly from the originator have preference over data that have passed through many users/processors, and possibly lost/changed precision or other information along the way. Special Case: merging profiles within the same cast In some cases, different variables from the same oceanographic cast have been submitted to the NODC/OCL at different times or from different sources. The most common example of this is when biological data (e.g., pigments, plankton measurements) are submitted for previously processed ocean cast data, which already loaded into WOD databases. Through the efforts of the GODAR project and the OCL Global Ocean Database project, many casts containing chlorophyll, nutrient, and plankton data have been acquired from the source Institutions and/or digitized, and combined with existing data in WOD. Information such as date, position, time, platform, and originator's cast number and/or cruise identifier is used to match up incoming casts with existing casts. Frequently, the match-up is obvious (e.g. the same ship is in the exact position on the same day, and the depth levels of the existing data correspond exactly to the incoming data). When the match-up is less obvious, efforts are made to determine whether this match is appropriate or not by reviewing the documentation, comparing cruise tracks, or contacting the data originator, if possible. When an appropriate match is made, the data are merged into one single cast which has all of the data and metadata of the previous two casts. When a match is uncertain, but platform, position and dates are very close, the casts are left separate and assigned the same WOD cruise number so the data will at least remain grouped by cruise number. 6. Depth inversion and depth duplication checks Depth inversions and duplication of depths were found in some profiles. A depth inversion occurs when an observation has a shallower depth than the observation directly preceding it. A depth duplicate is a reading which has the same depth as the reading immediately before it. In either case the second observation was always flagged, rather than trying to evaluate the data. Table 12 lists the flags assigned to the data. If, after an inversion or duplication, the next two depth observations were still shallower than the first reading, this observation and all subsequent observations were flagged. This usually occurred when two or more profiles have been sequentially entered together into a digital file with no separating header information between them. After this check, casts submitted with depths in reverse order (deeper depth first) were sorted so shallowest depth will appear first. Depth error flags are assigned if: a) The second of two successive depths is shallower than the first (a depth inversion), the second depth will be marked with a flag value = 1. b) Three successive depths are shallower than the first depth, every depth reading in the profile following the first will be marked with a flag value = 1. c) Two successive depth readings are equal, the second reading will be marked with a flag value = 1. All correct depths are marked with a flag value = 0. 7. High-resolution pairs check The high-resolution pairs check is implemented to ensure whether or not any incoming data have matches in the existing bottle (OSD) and/or high-resolution (CTD) datasets. This check is performed to link the data acquired during the oceanographic cast when bottle samples and CTD data taken at the exact same time and location. The check is done on incoming OSD or CTD data with temperature, salinity, and/or oxygen. The measured parameters itself are not checked. If there are high-resolution pairs found, the necessary secondary header code for “High-Res Pair” (see Table 4, code 13) is placed in both OSD and CTD datasets for paired casts. 8. Range checks on observed level data Range checks are used to screen the data for extreme values. Broad ranges have been established as a function of depth and oceanic basins (shown in Figure 1) for each variable. The range for a variable, in each region, is set large enough to encompass variations for all seasons and years. Ranges were determined using frequency distributions, statistical analysis, literature values, and atlases (e.g. GESECS (Bainbridge, 1980; Craig et al., 1981, Spencer et al., 1982), Southern Ocean Atlas (Gordon et al., 1982, Wyrtki, 1971)). Observed level data were compared with these ranges, and outliers were flagged with a range outlier flag. Table 11 lists the variables contained in the WOD13, the standard WOD units, and the Appendices containing the ranges set for these variables. The ranges in these appendices do not represent the minimum and maximum values in the basins, but rather indicates extent of values beyond which the data are believed to be erroneous. Figure 1.

Excessive gradient checks For each variable in Table 11, a check was made for “excessive decreases and increases in a value over a depth range”, or excessive gradients. A gradient was defined as: \[ gradient = \frac{v_2 - v_1}{z_2 - z_1} \] where \( v_1 \) = the value of the variable at the current depth level \( v_2 \) = the value of the variable at the next depth level \( z_1 \) = the depth (meters) of the current depth level \( z_2 \) = the depth (meters) of the next depth level

Table 11. Data Ranges for Quality Control Individual Variables in WOD13 Two types of gradients were checked, and marked as follows: • Excessive Gradients - a negative gradient, i.e. an excessive decrease in the value over depth. The criteria used to define “excessive” for each variable are listed in Table 13. Any value which exceeded this “maximum gradient value” (MGV) was marked with a gradient flag. • Excessive Inversions - a positive gradient, i.e. an excessive increase in value over depth. These criteria are presented in Table 13. Data which exceeded the “maximum inversion value” (MIV), were marked with an inversion flag. MGV/MIVs were determined from literature and/or by objectively reviewing the trends of the variable within the data. To better accommodate the differences in gradient ranges between surface and deep water (e.g. due to physical or biochemical influence), a different set of MIV/MGVs were used for depths above and below 400 meters. When dealing with high-resolution instruments (e.g. HCTD, XBT), a minimum depth difference of 3.0 meters was used when calculating the gradients (Equation 1). Table 12.

1For all variables, the MGV/MIV ranges (Z<400m), where Z denotes depth, were set high enough to exclude only values which are grossly incorrect. For salinity, these ranges are so large as to be nearly irrelevant for these checks. In addition, data were checked to distinguish zero as a value versus zero as a missing-value- indicator, particularly in the historical nutrient data. The zero sensitivity check will flag a zero value if a gradient decreases to zero at a rate greater than the MGV * ZSI (zero sensitivity indicator). For example, if ZSI is 2.00, the gradient must be twice as large as the MGV for that depth range. These values were assigned a flag = 4, equivalent to an observed level flag. 10. Observed level density checks Density checks were run on the observed level data to locate density inversions. This check was not used to flag temperature and salinity data from subsequent quality control, but was used to get an estimate of data quality prior to interpolation to standard levels. The check is the same as described in Section B.12, Standard level density check, except the values are divided by the depth difference between adjacent levels unless the difference is less than 3 meters, in which case a difference of 3 meters is used. 11. Vertical interpolation method Prior to the next step in the quality control procedure, the data are interpolated from observed levels to standard depth levels (listed in Table 14). Any data flagged as range outliers, excessive gradients, inversions, or depth errors were not used during interpolation to standard levels. This was applied when possibly during interpolation to standard levels. Table 14. Standard levels and depths (meters)

The interpolation scheme used is a modification from that described by Reiniger and Ross (1968) and noted by UNESCO (1991) as being in common usage. This scheme uses four observed values surrounding the standard level in question – the two closest shallower values and the two closest deeper values. The closest shallower and deep values ("inside" values) and the two farthest shallow and deep values ("outside" values) must be within the depth difference criteria shown in Table 15. The first set of depths in this table is the maximum distance between the depths of the "inside values". The second set of depths applies to the maximum distance between the depths of the “outside values”. This interpolation scheme has the advantage over three point Lagrangian interpolation of being less susceptible to extremes when a large gradient is encountered since two separate three-point Lagrangian interpolations are averaged and then fit to a reference curve. If all the above criteria are met, the variable value at the standard depth level is set by the Reiniger and Ross (1968) interpolation method. If there are not enough surrounding values within acceptable distances, three point Lagrangian interpolation is performed on the value above and two values below the level in question, or on the two values above and one value below depending on the number of observations above or below the selected depth. Modifications to the Reiniger and Ross (1968) method are the following: a) If the Reiniger and Ross interpolated value does not fall between the observed values directly above and below it, linear interpolation is substituted; b) If any observed value is recorded within 5 meters of the sea surface, this value is used as the surface value; Direct substitution (observed level depth equals the standard level depth) and the Reiniger and Ross (1968) interpolation account for most of the standard level values.

Note: Since many XBT data were reported only at “inflection points” (depth at which temperature changed by a specified amount from previous recorded value) interpolation limits were not used for XBTs. B. QUALITY CONTROL OF STANDARD LEVEL DATA 12. Standard level density check A standard level density check was used to eliminate spurious inversions due to interpolation (Levitus et al., 1994). Each profile was checked for static stability using Hesselberg and Sverdrup’s (1914) definition. The computation is a local one in the sense that adiabatic displacements between adjacent temperature-salinity measurements in the vertical are considered rather than displacements to the sea surface. The procedure for stability (\( E \)) computation follows that used by Lynn and Reid (1968): \[ E = \lim_{\delta z \to 0} \frac{1}{\rho_0} \frac{\delta \rho}{\delta z}, \] where \( \rho_0 = 1.02 \) g·cm\(^{-3}\) and \( z \) is depth in meters. As noted by Lynn and Reid (1968) the term is “the individual density gradient defined by vertical displacement of a water parcel”. For discrete samples, the density difference (\( \delta \rho \)) between two samples is taken after the deeper sample is adiabatically displaced to the standard level of the shallower depth. \( \delta \rho \) is then simply the displaced sample’s density minus the shallower sample’s density. Densities were calculated using the IGOSS standard density equation (Fofonoff et al., 1983) on interpolated temperature and salinity data. An inversion was defined as anywhere the \( \delta \rho \) was less than zero. For observations with a deeper sampling depth of 30 meters or less, an inversion of 3\( \times 10^{-5} \) g·cm\(^{-3}\) was considered an indication of a problem with the data. The temperature and salinity at both of these depths were flagged. For observations with a deeper sampling depth between 50 and 400 meters an inversion of 2\( \times 10^{-5} \) g·cm\(^{-3}\) was considered excessive. For depths greater than 400 meters any inversion greater than \( 10^{-6} \) g·cm\(^{-3}\) was considered excessive. If two or more such density inversion were found in one profile, all temperature and salinity values were flagged as unusable for this profile. 13. Statistical analysis of data at standard depth levels Observed level data were interpolated to standard levels, averaged by five-degree-squares, and simple statistics (mean, standard deviation, and number of observations) were computed for each depth level. Each five-degree square box was designated coastal, near coastal, or open ocean, depending on the number of one-degree by one-degree latitude-longitude grid boxes in the five-degree box which were land areas. The five-degree standard deviation multiplier file (sd_multiplier.msk) is available on the WOD masks page of the NODC website. Standard level data were flagged as follows: a) Coastal: The standard level data value exceeds 5 standard deviations computed within the 5x5 grid in the upper 50 m; b) Near-coastal: The standard level data value exceeds 4 standard deviations computed for 5x5 the grid in the upper 50 m; c) Open ocean: The standard level data value exceeds three standard deviations computed for the 5x5 grid, except when a profile was at or below the average depth level for the one-degree box in which it was contained, or any of the adjacent one degree boxes, then 4 standard deviations were used; d) If a cast contains four or more standard deviation failures, the whole cast is flagged. The reason for varying the standard deviation criterion is the expected high variability in shallow coastal areas due to river runoff and other factors. Also, high variability within a five-degree box near the ocean bottom can occur if the five-degree square box contains portions of two basins, e.g., the mid-Atlantic ridge separating east and west Atlantic waters. This check was only performed if there were five or more observations at this depth in the grid box. The standard deviation check was applied twice to the data and then new five-degree square statistics were computed to produce a new "clean" dataset. 14. Objective analysis Following the statistical check, standard level data were averaged by one-degree squares for input to the objective analysis (Boyer et al., 1998). The initial objective analyses for each variable at standard depth levels usually contained some large-scale gradients over a small area, or so-called “bullseyes”. These unrealistic features generally occurred because of the difficulty in identifying non-representative values in data sparse areas. “Bullseyes” and other questionable features are investigated and are flagged by identifying the profile or individual data points that created each unrealistic feature. In some extreme cases, entire cruises were flagged. These flags were applied to both the observed and standard level data. “Bullseyes” were investigated using property-property plots (e.g. temperature against dissolved oxygen), or variable as a function of depth and season within regional basins. IV. XBT DEPTH-TIME EQUATION Since the XBT system does not measure depth directly, the accuracy of the depth associated with each temperature measurement is dependent on the equation that converts to depth the time elapsed since the probe enters the water. Unfortunately, problems have been found in various depth-time equations used since the introduction of the XBT system. The original depth-time equation developed by Sippican for their T-4, T-6, T-7, and Deep Blue models underestimates the probe’s fall rate. At a given elapsed time, the falling probe is actually deeper than indicated by the original equation. Thus, the water temperatures are associated by the original equation with depths that are shallower than the actual depths at which they are measured. The error, first documented by Flierl and Robinson (1977), increases with increasing elapsed time reaching 21 meters, or about a 2.5% error, for depths around 800 meters. Sippican’s original equation was used by TSK for their T-4, T-6, T-7, and Deep Blue models, and by Spartan for their XBT-4, XBT-6, XBT-7, XBT-7DB, XBT-20, and XBT-20DB models. Although 2.5% in depth seems a small error, it can lead to overestimates of as much as 6% when calculating ocean heat content (Willis, 2004). In 1994, Hanawa et al. published an International Oceanographic Commission (IOC, 1994) report detailing a large study of XBT fall rates using different probes manufactured by Sippican and TSK and dropped in different geographic locations. A new depth-time equation, the Hanawa et al. equation, was given, as well as an algorithm for correcting depths for existing data collected using the original equation. The report emphasized the need to continue to archive existing data with the original depth equation only, applying the correction when necessary for scientific research. Sparton XBT-7 probes were studied by Rual et al., (1995, 1996). It was determined that the Hanawa et al. equation was suitable for use with these probes. Thadathil et al. (2002), however, suggest that the Hanawa et al. equation is not valid for measurements in high-latitude low temperature waters. Following the IOC 1994 report of Hanawa et al. (1994), TSK altered their software between January and March 1996 to make the Hanawa et al. equation the default equation (Greg Ferguson, personal communication). Sippican did the same around August 1996, (James Hannon, personal communication). However, a universal switch to the new software has not been made. As of mid-2005, data from XBT drops are recorded using both the original and Hanawa et al. depth-time equations. Kizu et al. (2005) published a new depth-time equation for the TSK T-5 probes, but no software has been released with their equation. Corrections to the depth-time equations for air dropped XBT probes (AXBT) manufactured by Sippican and Spartan were calculated by Boyd (1987) and Boyd and Linzell (1993b) respectively. More recently, Gouretski and Koltermann (2007) found that using the Hanawa equation still left a time and depth dependent bias, largest in the 1970s, smallest in the late 1980s-early 1990s, when most of the tests used by Hanawa were performed. Levitus et al. (2009) refined Gouretski and Koltermann (2007) statistics for the XBT bias and extended them through 2012 CORRECTIONS TO XBT DEPTH-TIME EQUATION ERRORS Before the various depth-time equations errors were widely known, a significant amount of data were recorded and archived without notation of what type of expendable probe was used. Approximately 55% of XBT temperature profiles in WOD13 have an instrument code of “XBT, type unknown”. Of these, most are positively identified as coming from shipboard drops. The remaining casts were dropped from unknown platforms. These missing ancillary metadata make it very hard to know whether the reported depths for a particular XBT profile were obtained with an incorrect depth-time equation. In the present, many XBT data are still recorded and archived with no indication of the depth-time equation used. This is particularly critical now, since there is more than one depth-time equation in use for many XBT types. The XBT data in the WOD13 at observed levels retain the depths received from the data submitter. For pre-1996 data, if second header code 33 has a value of “1”, the submitter corrected the depths based on a recalculated depth-time equation, otherwise second header 33 is absent. For XBT profiles taken on or after Jan. 1, 1996, second header 33 will be set to “0” if the depths were calculated using the original manufacturers depth-time equation, a “1” if the Hanawa et al. (1994) depth-time equation was used to calculate the depths. Second header code 33 is not present if the depth-time equation used is unknown for all data taken on or after Jan. 1, 1996. The XBT data in the WOD13 interpolated to standard levels uses the appropriate corrected depth equation when possible and the appropriate bias correction from Levitus et al. (2009). Since more than half of all XBT profiles are of type unknown, a test was applied to these data to see if a depth correction was necessary. If the greatest reported depth is less than 840 meters, the largest realistic depth for the probes with underestimated fall rates, the depths were corrected using the Hanawa et al. equation. It was assumed that, following the IOC recommendation, data available in the WOD13 was received at NODC with depths calculated using the original equations unless otherwise noted. The above assumption is not always valid for data collected since new depth-time equations became available on recording software released by each XBT manufacturer. For data collected since January 1996, if the depth-time equation used was not noted, the data were not corrected when interpolating to standard levels and were marked so as not to be used for depth sensitive calculations. Of a total of 300,434 XBT drops during the relevant time periods, there are 78,494 drops without depth-time equation information. An attempt to ascertain the depth-time equation information was made by contacting the data originators. Most of the data originators are large data centers and the information could not be recovered. The actual values of the reported depths can be used to recognize the depth-time equation used, when the full depth trace is reported (Donald Scott, personal communication). Although most data received at NODC comes with only selected depth levels, when possible, this technique was used. Secondary header 54 contains information on our decision as to whether the depths need correction for each XBT given the criteria listed above. This secondary header also carries information on exactly which corrected depth-time equation should be used to recalculate the reported depth values. Second header 54 is set to “-1” if there is not enough information to know whether a correction is necessary, “0” if no correction is necessary, and a positive value denotes which depth correction needs to be applied to the given observed depths. (See Appendix 2.20 (this document) or file s_54_needs_depth_fix.pdf for information on code table and how to correct depths.) IMPORTANT: THE OBSERVED LEVEL XBT DATA IN WOD13 ARE THE SAME DATA AS SUBMITTED BY THE ORIGINATORS. IF YOU ARE USING OBSERVED LEVEL XBT DATA FROM WOD13, PLEASE USE SECONDARY HEADER 54 TO SEE WHETHER A DEPTH CORRECTION IS NECESSARY. THE STANDARD LEVEL XBT DATA IN WOD13 WERE PREPARED, WHEN NEEDED AND POSSIBLE, USING A CORRECTED DEPTH-TIME EQUATION. IF YOU ARE USING STANDARD LEVEL XBT DATA FROM WOD13, PLEASE USE SECONDARY HEADER 54 TO SEE WHETHER A CORRECTED DEPTH-TIME EQUATION WAS USED, A CORRECTION WAS NOT NEEDED, OR A CORRECTION COULD BE NEEDED BUT THERE WAS NOT ENOUGH INFORMATION. THE XBT AND MBT DATA AT STANDARD LEVELS WERE ALSO CORRECTED FOR TEMPERATURE BIAS, AFTER LEVITUS ET AL. (2009). THE CORRECTIONS ARE YEAR AND DEPTH DEPENDENT AND ARE SHOWN ON THE XBT BIAS DEPTH AND TEMPERATURE CORRECTIONS PAGE AND THE MBT BIAS DEPTH AND TEMPERATURE CORRECTIONS PAGE OF THE NODC WOD/OCL PRODUCTS WEB PAGES. THERE ARE A NUMBER OF DIFFERENT XBT CORRECTIONS IN THE PUBLISHED CORRECTIONS ASIDE FROM THE LEVITUS CORRECTIONS. WODselect ALLOWS DOWNLOAD OF DATA USING EACH OF THE CORRECTIONS DETAILED IN THE ABOVE PAGE FOR OBSERVED LEVEL DATA. NO BIAS CORRECTIONS WERE MADE TO OBSERVED LEVEL DAT IN THE YEARLY OR GEOGRAPHICALLY SORTED DATA. V. TUTORIAL: Importing WOD13 data into Ocean Data View Ocean Data View (ODV) is used for visualization and analysis of oceanographic data by allowing the user to generate property-property plots, maps, and sections (transects). The software can be downloaded from ODV website. What follows is a tutorial on how to use WOD13 data in Ocean Data View (ODV). The example shown will use a downloaded file from the geographical location (WMO square) option (file APBO7515.gz; where APB denotes Autonomous Pinniped Bathymetermograph, O denotes observed level data; 7515 denotes the WMO code; and the extension gz denotes that the file is a gzip compressed file). To use this tutorial the user must have successfully installed ODV version 4.5.7 or higher. It is also important to add that this tutorial has been written for the Microsoft Windows XP and 2007 environment on personal computers. This document is not a substitute for the ODV User’s Guide. Please refer to the ODV User’s Guide for more information. Reading the data using Ocean Data View: ODV will read (import) selected WOD13 data files in gzip compressed or decompressed format as well as offer options for displaying the data. Examples 1 and 2 below illustrate how to open a new collection and import single and multiple data files into ODV. Example 1: Open a new data collection and import a single WOD13 data file (APBO7515.gz) into ODV. Select and extract the Autonomous Pinniped Bathymetermograph (APB) at observed depths with geographic coordinates between 50° and 60°N and between 150° and 160°W. Note the radio-buttons for selection among observed or standard depths are located above the WMO map. The region of interest is located in WMO square number 7515 (North Pacific) as shown in Appendix 7. Click WMO square 7515 to get to the data page specific to this geographical region. Selecting data by dataset type: On the data page for each ten-degree WMO square the data are organized by dataset. The file with the desired data is APBO7515.gz. Select and save APBO7515.gz to your work directory. Opening a new data collection: In the upper menu bar of ODV click the File tab to open the file menu. Then click New to create a New_ODV_Collection in your working directory (otherwise, any existing collection can be used if available). ODV will then request a name for the new collection. In Example 1, enter demo1s (as for “demo 1 single file”, or any other meaningful file name) in the File name window. Click Save. This will create the collection named demo1s.odv. Figure 2 shows ODV when a new collection is created and prior to importing data. Since no data have been imported, the ODV internal number of stations is zero, shown in the bottom of the window as 0/0: DefaultView* circled in red. ![ODV screen after creating a new collection and prior to importing data.](page_349_678_1017_355.png) Figure 2. ODV screen after creating a new collection and prior to importing data. Importing a single data file into the collection: The next step is to import data (APBO7515.gz). In the ODV File Menu select Import > NODC Formats > World Ocean Database. In the browser window point to the folder where you have placed the APBO7515.gz file. Using the Import Options dialog box (Figure 3) you can associate the variables of the imported data with the variables already defined in the collection. Now look at the bottom portion of the box that hows window called Variable Association. All of the variables defined as the WOD13 data are preceded by asterisks. To keep this exercise simple, we will not make any changes to the Source File or Target Collection. Please refer to the ODV manual for detailed information about advanced ODV features. Highlight APBO7515.gz so that it shows in the File name window and select Open to continue. Figure 3. ODV Import Options. A small dialog box (Figure 4) displays the total number of stations (9943 stations) imported from APBO7515 into the ODV Global Map. Click OK to continue. ![ODV Import Completion Dialog Box.](page_246_180_1057_312.png) Figure 4. ODV Import Completion Dialog Box. When the user selects World Ocean Database format, distribution of the imported data will appear in the Global Map. The ODV screen also displays all depth-dependent variables in WOD13 (see Table 3) and their values. A zoom of the information displayed to the right of the Global Map is shown in Figure 5. The station information changes accordingly, as you click a station in the distribution map. All the information corresponds to the WOD13 format unless specified otherwise. Some cast information such as profile bottom depth might not exist in all casts. Note that once a collection has been created, it is possible to import additional data files into the same collection. Figure 5. WOD13 cast information and profile data as displayed by Ocean Data View (ODV). Example 2: Open a new collection and import several OSD data files into ODV. Opening a new data collection: In the ODV menu bar click the File tab to open the File Menu. Click New to create a New_ODV_Collection in your working directory (or you can open any existing collection if one is available). ODV will then request a name for the new collection under File Name. Enter demo2m (i.e. demo 2 multiple files; or any other file name) in the File Name box and click Save. This will create the collection file named demo2m.odv. Importing multiple data files into the collection: In the ODV File Menu bar, select Import > NODC Formats > World Ocean Database. In the browser window, select the folder where you have placed the files to import. Hold down the shift key to select all files in the folder, or hold down the control key to select certain files. Click Open to continue. When importing is completed, data distribution will appear in the Global Map. The Importing ... dialog box will show the number of imported stations. For this exercise, 13,675 stations where imported from files: OSDO7201.gz, OSDO7202.gz, and OSDO7203.gz, see dialog box shown in Figure 6. ![ODV Importing stations from multiple files.](page_495_682_627_180.png) Figure 6. ODV Importing stations from multiple files. Mapping of WOD variable quality flags: When a user creates a WOD collection using the WOD variables, ODV imports the original WOD quality flags and automatically maps these flags in the imported files to the ODV collection. The WOD variable quality flags are shown in Table 12. The WOD variables that received full quality control are: temperature, salinity, oxygen, phosphate, silicate, and nitrate. Other WOD13 variables received limited quality control such as basin data ranges for: pH, Chlorophyll, Alkalinity, Partial pressure of carbon dioxide, Dissolved Inorganic carbon, Tritium, Helium, Delta Helium-3, Delta Carbon-14, Delta Carbon-13, Argon, Neon, Chlorofluorocarbon 11, Chlorofluorocarbon 12, Chlorofluorocarbon 113, and Delta Oxygen-18. Reporting data problems, suggestions, comments about WOD13: If any errors are found in the WOD13, please contact the Ocean Climate Laboratory at OCL.help@noaa.gov and the problems will be corrected. Comments or suggestions for improving WOD13 would be appreciated. Updates to the programs and changes to WOD13 will be posted in the NODC WOD Updates page. VI. FREQUENTLY ASKED QUESTIONS What follows are answers to basic users’ questions about WOD13. They are included here to answer any questions that may arise as you read this document as well as work with the data. Where do I get WOD13 data? The data are available online or on DVD. DVD: If the user requires all the data, or a large subset, ordering the DVD is the best option. The DVD can be ordered by sending E-mail to NODC.Services@noaa.gov or through the NODC online store at http://www.nodc.noaa.gov/General/getdata.html. Data on the DVD are sorted by year (time) only. The year-sorted data are provided in the DATA folder on the DVD. Online: Geographically-sorted option: http://www.nodc.noaa.gov/OC5/WOD13/data13geo.html - Data are sorted into 10° World Meteorological Organization (WMO) squares (Appendix 7). Within each 10° square, the data are sorted chronologically. There are separate files for each dataset for each 10° square for both observed and standard level data. Surface-only data are all contained in one file, regardless of geographic position. Online: Chronologically-sorted option: http://www.nodc.noaa.gov/cgi-bin/OC5/WOD/getyearlydata.pl?Go=TimeSorted - Data are sorted by year. Each year for each dataset has a separate file for both observed and standard level data. Surface-only data (SUR) are all contained in one file, regardless of year. Online: User subset option: http://www.nodc.noaa.gov/OC5/SELECT/dbsearch/dbsearch.html - This tool, called WODselect, allows the user to generate their own subset of data, based on a number of criteria, including geographic location, date, platform, project, institute, primary investigator (PI), measured variables, dataset, and quality-control flags. The data are available both in native format and in a comma-delimited (csv) format. The data can be separated by dataset or combined in one set of files. The number of files is based on the size of the subset requested and the maximum file size supported by the ftp site. The data are compressed, how do I uncompress the data? The compression routine used on the files is gzip, denoted by the .gz file name extention. Many commercial software packages are able to decompress files compressed using gzip. If you are in a point and click environment, double click on the WOD file, and if your default decompression software recognizes the .gz extension, the decompression should proceed automatically, possibly with some user prompting, depending on software used. If you do not have commercial software, gzip decompression utility is freeware and it is available at http://www.gzip.org. The gzip utility is available in the UTILS folder on the DVD. How do I work with the WOD data? The WOD native format is an ASCII format (Tables 10.1, 10.2, and 10.3) developed for compactness. As such, it appears in a text editor as a “B” followed by a string of numbers (see Appendix 8 for sample output). Despite increases in computer memory and bandwidth, compactness is a desirable attribute when downloading data. We have provided a number of choices for working with the data: Constructing your own reading utility: A detailed format description for WOD is provided in Section II (this document) followed by the ASCII format listing. From this description you can create your own reading software in your preferred language. Using the FORTRAN and C utilities provided by the Ocean Climate Laboratory: http://www.nodc.noaa.gov/OC5/WOD/wod_programs.html contains sample FORTRAN and C programs for reading the WOD native format. The basic programs are wodFOR.f and wodC.c. The user can add output routines to these programs to display the data in their preferred format. Executables compatible with Microsoft operating systems are also included. wodASC.f and wodSUR.f will read the WOD native format data and output the data in a comma or space delimited format. This format can be used in software such as MatLab and other. The utilities are also provided in the PROGRAMS folder on the DVD. Importing into Ocean Data View: Ocean Data View (ODV) is freeware developed by Dr. Renier Schlitzer at the Alfred Wegener Institute. It is used for viewing oceanographic profile data with features such as property-property plots and ocean sections. ODV can be freely used and distributed for non-commercial research and teaching purposes. The software is made available in the ODV folder on the WOD13 DVD. The software can be downloaded from http://odv.awi.de/. If you use ODV for your scientific work, you must reference it in your publication as follows: Schlitzer, R., Ocean Data View, http://odv.awi.de, 2013. Commercial use of ODV: If you plan to use Ocean Data View or any of its components for commercial applications and products, you need to obtain a software license. Please contact the address below for further information: © 1990 – 2013 Reiner Schlitzer, Alfred Wegener Institute Columbusstrasse 27568 Bremerhaven, Germany E-mail: Reiner.Schlitzer@awi.de A brief tutorial on importing WOD data into ODV is available in Section V and on line at: http://www.nodc.noaa.gov/OC5/WOD13/docwod13.html. How do I use the WOD quality-control flags? WOD quality control flags are the flags set during automatic and subjective quality control steps in the calculation of WOA13 climatologies. There are separate flags for each profile in a cast (temperature, salinity, phosphate, etc.). There are three types of flags. Whole profile flags denote failed checks for an entire profile; these flags are the same for observed and standard level data. Observed level flags are flags for individual measurements in a profile. Standard level flags are flags for individual interpolated values on standard levels. A complete list of flags can be found in Table 12. A more detailed description of the quality-control procedures can be found in Section III. The flags are not broken down into good/questionable/bad. Each automatic or subjective check has its own flag value. The user can decide whether to use all flags, no flags, or only flags set by selected quality-control checks. Note that all data is included in WOD13 even if it appears to be of questionable quality. It is therefore advised that the included quality-control flags are used. How do I use the originators quality-control flags? Quality-control flags are included in the data as received by NODC are often included with individual measurements. There are no ‘whole profile’ or ‘standard level’ originator’s flags. Often, the data originator may have more knowledge of submitted data than NODC. The originator’s flags are used to help identify possible unrepresentative data, but they are not always used to set WOD quality control flags. The user of the data may prefer to use the originator’s quality control flags instead of the WOD quality control flags. If a cast has originators flags, second header 96 contains a code that will indicate which set of originator’s flags was used. Appendix 2.26 gives a list of values for each set of originator’s flags. How do I report data problems in WOD13? Despite the large amount of time and efforts invested in quality control of WOD13, problems still exist. We encourage anyone who encounters a problem, or has a question, to contact us at OCL.help@noaa.gov. How is the XBT fall-rate problem handled? As per the international agreement detailed in Hanawa (1994), all observed level XBT data are stored as we received them, without any type of depth correction. However, all necessary information needed to make depth corrections when necessary is available in the second header information of each XBT cast. For details on the XBT fall-rate problem and how to perform depth correction, see Section IV. How do I access the plankton data in WOD13? The plankton data are included with the physical data in the same WOD native format. The description of the portion of the format devoted to plankton data is provided in Tables 10.2 and 10.3. Descriptions of all the codes used to describe the plankton data are on Appendices 4 through 6. A detailed description of the plankton database is described in Chapter 14 of the WOD13 (Boyer et al., 2009). Another alternative is to download the plankton data or a subset of plankton data using WODselect. The output can be requested in WOD native format, or in csv format. The later writes out all the code values found in the WOD native format as well as the codes themselves. VII.

ACCEPTABLE RANGES OF OBSERVED VARIABLES AS A FUNCTION OF DEPTH, BY BASIN The range values provided has range values for temperature, salinity, oxygen, phosphate, silicate, nitrate, pH, chlorophyll, and alkalinity. The range values in the tables are used to help identify the most obvious questionable values for these variables. Please note that ranges are given on 33 standard levels (+ one for depths deeper than 5500 m). All standard depths in between given standard depths have the same values as the nearest standard depth shown (for example, 90m standard depth uses 100m range values. If a standard depth is equidistance between two shown standard depths, the ranges values will be the same as the shallower shown standard depth (i.e. 5 m range values will be the same as 0 m shown values, not 10 m shown values). 9.1.

Glossary Accession Number – A group of stations received and archived at the U.S. NODC. Each dataset submitted to NODC is given a unique accession number. Using this number, a user can get the original data from NODC as well as information about the data itself. Cruises are not always subsets of accession numbers, as data from the same cruise may come from multiple accession numbers. Each station has an accession number (with a few exceptions). If a station is replaced by higher quality data, the accession number will reflect the new source of the data while the unique station number will remain unchanged. If a profile for a variable not previously stored with a station becomes available, the profile will be added to the existing station, and a profile specific accession number will be added to the station to record the source of the new profile. Accuracy – ability of a measuring instrument to give responses close to a true value ASCII data format – Native format used in the World Ocean Data series APB – Autonomous pinniped bathythermograph is the name given to temperature data recorded by time-temperature-depth recorders (TTDR) and ARGOS position transmitters attached to pinnipeds (e.g. northern elephant seals). See http://www.imma.org/pinnipeds/ for information on the different pinniped species. Bathythermograph (BT) data – Temperature profile data from mechanical bathythermographs (MBT), and expendable bathythermographs (XBT) Biological header – The biological header section contains information on the sampling methods used for collecting taxonomic and biomass measurements. Bullseyes – Bullseyes are unrealistic features found during the intial objective analyses for each variable at standard depth levels and usually contain some large-scale gradients over a small area. The data causing these features are investigated and flagged. Calibration – A set of operations that establish, under specified conditions, the relationship between the values of quantities indicated by a measuring instrument or measuring system and the corresponding values realized by standards. Cast – A set of profiles (or a single profile) taken concurrently. Meteorological and ocean condition information are also included for a cast if measurements were taken concurrently with the profile(s). Observations and measurements of plankton from net-tows are included if taken concurrently or in close time proximity to profiles. If there are no profiles in close proximity, a net-tow by itself will constitute a cast. Each cast in the WOD13 is assigned a unique cast number. If the cast is subsequently replaced by higher quality data, the unique cast number remains the same. If any alteration is made to a cast, this information is noted online, referenced by the unique cast number. For surface-only data in dataset SUR, a cast is defined as a collection of concurrent profiles of surface measurements at discrete latitudes and longitudes over an entire cruise (see definition of cruise below). Profiles of latitude, longitude and Julian year-day are included with profiles of measured oceanographic variables. Cast/Tow Number – Sequential number representing each over-the-side operation or discrete sampling at a station or section or a cast of a tow. Character Data – Includes originator’s cruise codes, originator’s cast codes, and principal investigator integer code. Comma Separated Value – Also known as “common-delimited” is a text file or flat file format allowing portability of files into any database. Country code – A two-character code assigned to each country. Each code is unique to a country and is assigned by NODC. See Appendix 1 for the complete list of country codes. Cruise – A set of casts is grouped together if they fit the cruise definition. A cruise is defined as a specific deployment of a unique platform for the purposes of a coherent oceanographic investigation. For an oceanographic research vessel, this deployment is usually well defined with a unique set of scientific investigators collecting data for a specific project or set of projects. In some cases different legs of a deployment with the same equipment and investigators are assigned different cruise numbers, as per the investigators designation. In the case of merchant ships of opportunity, a cruise is usually defined as the time between major port calls. Profiling floats, moored buoys, and drifting buoys are assigned the same cruise number for the life of the platform. For surface-only data in dataset SUR, a cast and cruise are the same, except for 27 cruises which were split into 2 casts each due to the large number of sets of measurement (> 24,000). In WOD13, a cruise identifier consists of two parts, the ISO 3166-1 country code and the unique cruise number. The unique cruise number is only unique with respect to the country code. The country code is usually assigned based on the flag under which the ship from which the data were measured operates. If the platform from which data were measured was not a ship, (e.g. profiling float, moored buoy), the country of the primary investigator or institute which operates or releases the platform is used. For data for which no information on country is present, a country code of 99 is used. For data for which there is no way to identify a specific cruise, a cruise number of zero (0) is used. The present cruise identifier definition is slightly changed from previous releases of the World Ocean Database. Previously, bathythermograph (BT) data were assigned unique cruise numbers without regard to country in keeping with prior convention at the US NODC. This made assigning the same cruise number to BT data and other data collected on the same cruise impossible. Now BT cruises are assigned in the same manner as other datasets. To facilitate this change, approximately 5,300 Mechanical Bathymeterograph (MBT) cruise numbers were reassigned, along with 22 Expendable bathythermographs (XBT) cruise numbers. Now, all data for a cruise should be listed under one unique country code/unique cruise number combination. It should be possible to get all bottle, high-resolution CTD, BT, and towed-CTD data for a cruise using one unique cruise identifier. However, this is not yet the case for all BT data. It is an ongoing project to match the BT data with the correct bottle and high-resolution CTD data. Cruise Code – A unique code assigned to all casts completed in the same cruise. It is formed by a country code and a number. CTD – Conductivity-Temperature-Depth. Data contains physical-chemical oceanographic data at discrete pressure levels. Dataset – All casts from similar instruments with similar resolution. For instance, all bathythermographs (BTs) which are dropped over the side of a ship on a winch and recovered are in dataset MBT, all CTD data stored at high-resolution (small depth increments or large number of measurements) are stored in CTD. A list of all datasets for WOD13 is found in Table 2. For convenience, data from each dataset are stored in separate files in WOD13. DRB – Drifting Buoy Data. g77 compiler – g77 is a GNU Fortran compiler that was initially designed to replace the UNIX f77 command, a UNIX compiler. See http://gcc.gnu.org/onlinedocs/gcc-3.4.1/g77/ as well as http://www-rocq.inria.fr/~kern/G77/g77.html for more information. GLD – Glider Data. Institute code – A unique numerical code assigned to each institute which sampled the data. ISO – International Organization for Standardization. It is a widely used coding system and is the largest developer and publisher of International Standards in the world. We see it used everyday: 1) used to ID the Internet country code Top-Level Domains like “.fr”, “.jp”, “.ru”, 2) representation for currencies & funds (US dollar, Japanese Yen, Euro, Russian Rubble, etc. See http://www.iso.org/iso/home.htm for more information. MBT – Mechanical Bathythermograph. The data contains temperature-depth profile obtained at discrete depths to a maximum depth less than 300 meters. Measured Variables – Temperature, salinity, oxygen, phosphate, silicate, nitrate, pH, chlorophyll, alkalinity, PCO₂, DIC, Nitrate+Nitrite, and pressure data versus depth. meq Milli-equivalents MRB – Moored Buoy Data μM Micromolar Observed level/depth – The depth or pressure at which an in-situ measurement was collected as reported by the originator of the data. Ocean Archive System – The Ocean Archive System contains metadata of all of the data received and accessed at the National Oceanographic Data Center (NODC). It assigns unique accession numbers, maintains internal data management information and it maintains a control vocabulary (Principal Investigators, Projects, Institutions, Platforms, etc.). Originator’s Cast Number – Numeric cast number assigned by the data submittor or data originator. Originator’s unit(s) – These are the units under which the data were reported to NODC. OSD – Ocean Station Data (also known as Bottle Data). The data contain physical-chemical-biological oceanographic data recorded at discrete depth (or pressure) levels. PFL – Profiling Float Data Platform Code – See Ship code. Principal Investigator – Principal Investigator is … Probe type – OSD, MBT, XBT including XCTD, CTD including STD, SUR, UOR, APB, PFL, DRB, MRB GLD. They correspond to the databases within the WOD main database. Some of the probes are named after the instruments that collected the data. Profile – A set of measurements for a single variable (temperature, salinity, etc.) at discrete depths taken as an instrument drops or rises vertically in the water column. For surface-only data, the profile consists of measurements taken along a horizontal path. For moored buoys and drifting buoys, the instrument does not move vertically in the water column, so a profile is a discrete set of concurrent measurements from the instruments at different depths attached to the buoy. Precision – number of digits to the right of the decimal point. Primary headers – The primary header contains information about the number of bytes in the cast, a unique WOD number which identifies each cast, the ISO country code, a cruise number, date, time, position, and the number and type of variables in the cast. Quality Control – Data received by NODC/OCL are put through a set of quality control procedures to ensure that: 1) the data are converted to the WOD format correctly, 2) the data format provided with the data is correct and the data itself have not been corrupted in transmission, 3) only one copy of data at each cast is retained in the WOD format, 4) the data are of good quality. Secondary Header – Contains information such as meteorological data, water column characteristics (i.e. depth to bottom), information about the instrument used, ship, institute, and project. Ship Code – A unique code which identifies the ships associated with the data. Also called platform code. Significant digits – The total number of digits stored in a WOD parameter value. Standard level/depth – A depth below the sea surface at which water properties should be measured and reported, either directly or by interpolation, according to the proposal by the International Association of Physical Oceanography in 1936. Station – Data from one or more casts at one geographic location. SUR – surface data are surface-only variables which are treated differently from profile data in the database. For surface-only data, each cruise is treated as though it were a single cast with depth, latitude, longitude, and Julian year-day associated with each measurement value. Taxa-specific and biomass data – Contains plankton weights, volume, and/or concentrations, for an entire sample (biomass) or for individual groups of organisms (taxa-specific). Unique Cast Number – A number assigned by the WOD database to a cast. This number remains unique to that cast. UOR – undulating oceanographic recorder is the generic name given to towed vehicles carrying measuring devices (usually CTDs) which ascend and descend through the water column in a more or less regular pattern, giving a two-dimensional view of the water column along the path in which the vehicle is towed. Variable – physical-chemical-biological measurements (e.g. temperature, salinity, oxygen, phosphate, nitrate, etc.) as well as latitude, longitude, julian-day, etc. See Table 3 for a complete list of variables. Variable specific secondary header – Contains information specific to each individual variable such as original units and methods for a given cast. WOD – World Ocean Database WMO – World Meteorological Organization of the Untied Nations, Geneva, Switzerland. The WMO Code is an international nomenclature adopted by the World Meteorological Organization based on 10-degree squares. XBT – Expendable Bathythermograph. It is the successor of the MBT instrument. The data contains temperature-depth profiles taken at discrete depths. Standard XBTs normally obtain profiles to depths of 450 and 760 meters. Other expendable bathythermographs reach a depth of 1830 meters.
