Nearly two-thirds of our planet is covered by water with more than 120 million Americans living near an ocean or Great Lake. Growing worldwide demand for natural resources will increase our dependence on coastal and marine environments while people, infrastructure, and ecosystems face increasing risks from hazards. USGS Coastal and Marine Hazards and Resources scientists and staff study coastal and ocean resources and processes from shorelines and estuaries to the continental shelf and deep sea so that we can fulfill our vision for a nation prepared for coastal and ocean changes.

“The USGS is proud to be an interagency partner in the efforts to increase American exploration of our planet’s ocean..." - Dr. Jim Reilly, USGS Director. Read the White House News Release from June 11, 2020.
