The oceanographic databases described by this atlas series greatly expands on the *World Ocean Database 1998* (WOD98) product. We have expanded these earlier databases to include data from new instrument types such as profiling floats and new variables such as pCO$_2$ and TCO$_2$. Previous oceanographic databases including the NODC/WDC profile archives, and products derived from these databases, have proven to be of great utility to the international oceanographic, climate research, and operational environmental forecasting communities. In particular, the objectively analyzed fields of temperature and salinity derived from these databases have been used in a variety of ways. These include use as boundary and/or initial conditions in numerical ocean circulation models, for verification of numerical simulations of the ocean, as a form of "sea truth" for satellite measurements such as altimetric observations of sea surface height, and for planning oceanographic expeditions. Increasingly nutrient fields are being used to initialize and/or verify biogeochemical models of the world ocean. The databases, and products based on these databases, are critical for support of international assessment programs such as the Intergovernmental Program on Climate Change (IPCC) of the United Nations.

It is well known that the amount of carbon dioxide in the earth's atmosphere will most likely double during the next century compared to CO$_2$ levels that occurred at the beginning of the Industrial Revolution. Regardless of one's scientific and/or political view of a possible "enhanced greenhouse warming" due to the increase of carbon dioxide, it is necessary that the international scientific community have access to the most complete historical oceanographic databases possible in order to study this problem, as well as other scientific and environmental problems.

The production of oceanographic databases is a major undertaking. Such work benefits from the input of many individuals and organizations. We have tried to structure the data sets in such a way as to encourage feedback from experts around the world who have knowledge that can improve the data and metadata contents of the database. It is only with such feedback that high quality global ocean databases can be prepared. Just as with scientific theories and numerical models of the ocean and atmosphere, the development of global ocean databases is not carried out in one giant step, but proceeds in an incremental fashion.

In the acknowledgment section of this publication we have expressed our view that creation of global ocean databases is only possible through the cooperation of scientists, data managers, and scientific administrators throughout the international community. I thank my colleagues at the Ocean Climate Laboratory of NODC for their dedication to the project leading to publication of this atlas series. Their commitment has made this database possible. It is my belief that the development and management of national and international oceanographic data archives is best performed by scientists who are actively working with the data.

This work was made possible by a grant from the NOAA Climate and Global Change Program which enabled the establishment of a research group, the Ocean Climate Laboratory (OCL), at the National Oceanographic Data Center. The purpose of the OCL is to prepare research quality oceanographic databases, as well as to compute objective analyses of, and diagnostic studies based on, these databases.

The data made available as part of this atlas include a part of the oceanographic data archives maintained by NODC/WDC as well as data acquired as a result of the IODE/IOC “Global Oceanographic Data Archaeology and Rescue” (GODAR) project. At NODC/WDC, “data archaeology and rescue” projects are supported with funding from the NOAA Environmental Science Data and Information Management (ESDIM) Program and NOAA Climate and Global Change Program. The majority of funding for these efforts is now provided by the ESDIM program. Support for this work from joint NASA/NOAA and DOE/NOAA Global Change data management programs is appreciated. Support for some of the regional IOC/GODAR meetings was provided by the MAST program of the European Union.

We acknowledge the scientists, technicians, and programmers who have submitted data to national and regional data centers as well as the managers and staff at the various data centers. Our database allows for the storage of metadata including information about Principal Investigators to recognize their efforts.

The OCL expresses thanks to those who provided comments and helped develop an improved *World Ocean Database 2001* (WOD01) product. In particular, Steve Worley of NCAR and Steve Hankin of PMEL for testing the CD-ROMs prior to distribution; Roy Lowry (BODC) for help with the BODC project data; and Tom Whitworth (TAMU) for information on database problems. Any errors in WOD01 are the responsibility of the Ocean Climate Laboratory.

Ervin Godfrey Trammell and Charlotte Sazama of the NODC International Data Exchange Team helped locate data in the WDC archives for digitization. We thank Mike Chepurin, Igor Minin, Dan Smolyar, Alexandra Grodsky, and Carla Forgy of the OCL for their work in data digitization and their assistance in quality control of the data and metadata in WOD01. Renee Tatusko identified many missing metadata. The OCL acknowledges the help received over the last several years from colleagues in other NODC divisions. Francis Mitchell helped with all the code lists and accessions, Melanie Hamilton supplied GTSPP data.

Declassification of naval oceanographic data by various navies is acknowledged. The Intergovernmental Oceanographic Commission has requested such declassification efforts in recent years.

ABSTRACT

This atlas describes a collection of scientifically quality controlled Ocean Station Data (OSD) temperature, salinity and oxygen profiles. Yearly distributions for individual years of all OSD temperature, salinity and oxygen profiles in the database are presented to provide information on the state of ocean OSD profile observations.

1. INTRODUCTION

Ocean Station Data (OSD) has historically 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 two most commonly used bottles are the Nansen and Niskin bottles. Data that are in the OSD files are frequently referred to as “bottle data” and the entire collection of data from these files may be alternatively referred to as the “Bottle Data File”. WOD01 includes measurements of temperature, salinity, oxygen, nitrate, nitrate+nitrite, phosphate, silicate, pCO$_2$, tCO$_2$, pH, alkalinity, chlorophyll and plankton.

2. OCEAN STATION DATA (OSD) TEMPERATURE, SALINITY AND OXYGEN PROFILE DISTRIBUTIONS

Figure 1 shows the number of OSD temperature profiles contained in WOD01 for the world ocean as a function of year. Figures 2 and 3 show the time series for the southern and northern hemispheres respectively. Figure 4 shows the distribution of OSD temperature profiles contained in WOD01 for the world ocean. There are a total of 1,951,157 OSD temperature profiles for the entire World Ocean with 201,642 profiles (10.3 %) measured in the southern hemisphere and 1,749,515 profiles (89.7 %) measured in the northern hemisphere. Table 1 provides the number of OSD temperature profiles included in WOD01 as a function of year. Tables 2 and 3 show the numbers for the southern and
northern hemispheres respectively. The geographic distribution of OSD temperature profiles for individual years for 1900-2001 are shown in Appendix A, Figures A1-A102. Most profiles have been made in the northern hemisphere, but the southern hemisphere coverage has been increased due to international data archaeology and rescue efforts and the World Ocean Database project (Levitus et al. 1994, 2002).

Figure 5 shows the number of OSD salinity profiles contained in WOD01 for the world ocean as a function of year. Figures 6 and 7 show the time series for the southern and northern hemispheres respectively. Figure 8 shows the distribution of OSD salinity profiles contained in WOD01 for the world ocean. There are a total of 1,767,288 OSD salinity profiles for the entire World Ocean with 192,827 profiles (10.9 %) measured in the southern hemisphere and 1,574,461 profiles (89.1 %) measured in the northern hemisphere. Table 4 provides the number of OSD salinity profiles included in WOD01 as a function of year. Tables 5 and 6 show the numbers for the southern and northern hemispheres respectively. The geographic distribution of OSD salinity profiles for individual years for 1900-2000 are shown in Appendix B, Figures B1-B101. Most profiles have been made in the northern hemisphere, but the southern hemisphere coverage has been increased due to international data archaeology and rescue efforts and the World Ocean Database project (Levitus et al. 1994, 2002).

Figure 9 shows the number of OSD oxygen profiles contained in WOD01 for the world ocean as a function of year. Figures 10 and 11 show the time series for the southern and northern hemispheres respectively. Figure 12 shows the distribution of OSD oxygen profiles contained in WOD01 for the world ocean. There are a total of 586,443 OSD oxygen profiles for the entire World Ocean with 122,035 profiles (20.8 %) measured in the southern hemisphere and 464,408 profiles (79.2 %) measured in the northern hemisphere. Table 7 provides the number of OSD oxygen profiles included in WOD01 as a function of year. Tables 8 and 9 show the numbers for the southern and northern hemispheres respectively. The geographic distribution of OSD oxygen profiles for individual years for 1900-2000 are shown in Appendix C, Figures C1-C99. Most profiles have been made in the northern hemisphere, but the southern hemisphere coverage has been increased due to international data archaeology and rescue efforts and the World Ocean Database project (Levitus et al. 1994, 2002).

4. APPENDIX A: DISTRIBUTIONS FOR INDIVIDUAL YEARS OF ALL OCEAN STATION DATA (OSD) TEMPERATURE PROFILES IN WOD01

This appendix contains yearly distributions of all OSD temperature profiles contained in WOD01. These maps provide some history of the observational progress of the field of oceanography. They also serve as indicators of whether or not a particular data set from a scientist or institution is part of the NODC/WDC-A archive. The exchange of information provided by the publication of such maps has provided us with valuable information about deficiencies in the database. The locations of all WOD01 OSD temperature profiles are plotted including stations that may be erroneously located over land. However, WOD01 contains some stations from various lakes so care should be exercised in the use of these stations and the determination as to whether they represent errors in locations.

For all figures in Appendix A, a small dot indicates a one-degree square containing from one to four stations and a large dot indicates five or more stations.

5. APPENDIX B: DISTRIBUTIONS FOR INDIVIDUAL YEARS OF ALL OCEAN STATION DATA (OSD) SALINITY PROFILES IN WOD01

This appendix contains yearly distributions of all OSD salinity profiles contained in WOD01. These maps provide some history of the observational progress of the field of oceanography. They also serve as indicators of whether or not a particular data set from a scientist or institution is part of the NODC/WDC-A archive. The exchange of information provided by the publication of such maps has provided us with valuable information about deficiencies in the database. The locations of all WOD01 OSD salinity profiles are plotted including stations that may be erroneously located over land. However, WOD01 contains some stations from various lakes so care should be exercised in the use of these stations and the determination as to whether they represent errors in locations.

For all figures in Appendix B, a small dot indicates a one-degree square containing from one to four stations and a large dot indicates five or more stations.

5. APPENDIX C: DISTRIBUTIONS FOR INDIVIDUAL YEARS OF ALL OCEAN STATION DATA (OSD)OXYGEN PROFILES IN WOD01

This appendix contains yearly distributions of all OSD oxygen profiles contained in WOD01. These maps provide some history of the observational progress of the field of oceanography. They also serve as indicators of whether or not a particular data set from a scientist or institution is part of the NODC/WDC-A archive. The exchange of information provided by the publication of such maps has provided us with valuable information about deficiencies in the database. The locations of all WOD01 OSD oxygen profiles are plotted including stations that may be erroneously located over land. However, WOD01 contains some stations from various lakes so care should be exercised in the use of these stations and the determination as to whether they represent errors in locations.

For all figures in Appendix C, a small dot indicates a one-degree square containing from one to four stations and a large dot indicates five or more stations.
