Description:The Integrated Ocean and Coastal Mapping (IOCM) Program at NOAA seeks to “map once, use many times.” In order to fulfill this goal across many mapping sectors, IOCM advocates that everyone share their mapping data with officially recognized, central repositories such as NOAA’s National Centers for Environmental Information (NCEI), the national archive for geophysical ocean and coastal data. Bathymetry is one type of data that has broad application and is logistically difficult to collect, so every survey mile collected is valuable and potentially useful for multiple purposes. From July to August 2020, NOAA’s IOCM program sponsored a geophysical data mining effort of U.S. Geological Survey (USGS) websites. The USGS Coastal and Marine Hazards and Resources Program (CMHRP) has high quality ocean mapping data of different types that are not fully mirrored at NCEI, including bathymetry. Archiving copies of the USGS CMHRP’s raw and processed bathymetric data at NCEI would increase public accessibility and allow the data to be incorporated into products like the U.S. Bathymetry Gap Analysis, which tracks how much of U.S. waters remain unmapped, and other data assemblies, e.g., Global Multi-Resolution Topography and the General Bathymetric Chart of the Oceans. This memorandum documents the methods used to mine data from USGS CMHRP websites and provides recommendations to others who may seek to extract future bathymetry data from these websites.
