Depth Contours for select locations across the U.S. Pacific Islands
These data are depth contours (isobaths) derived at 50 meters for most islands and reefs in the Mariana Archipelago, American Samoa, and the Pacific Remote Island Areas. Contours at 10- or 20-meter depths have also been derived for a subset of the same locations. These contours are derived from bathymetry sources including multibeam data collected by Coral Reef Ecosystem Program (CREP) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) since 2003, NOAA nautical charts, estimated depths derived from satellite images, and other sources of bathymetry collected by various agencies and entities.
