Map of the 200 nautical mile U.S. Exclusive Economic Zone

The 200-nautical mile U.S. Exclusive Economic Zone is shown in dark gray on the map. The CMHRP has collected sediment thickness data for defining the extended continental shelf—the shelf beyond 200 nautical miles—in the Arctic and Atlantic Oceans and the Bering Sea (yellow tracks).  

*In accordance with EO 14172, Restoring Names that Honor American Greatness, all USGS maps and figures moving forward will use the appropriate label Gulf of America. Per USGS practice, historical publications and media files will retain the name Gulf of Mexico as it was called at the time of initial publication.
