Service Description: The NOS Seabed Map Service provides access to brief descriptions of the composition of the sea floor from over 200,000 locations, primarily in U.S. coastal areas. The descriptions were produced by the NOAA National Ocean Service (NOS), and its predecessor, the U.S. Coast and Geodetic Survey (USCGS), from small geologic samples that were collected during hydrographic surveys to determine bottom type for charting purposes.

Learn more about the NOS Seabed Descriptions database

The points are assigned random colors, based on the survey ID of the corresponding NOS hydrographic survey. Points from the same survey will have the same color.
