Ocean Resources

The USGS Law of the Sea project helps to determine the outer limits of the extended continental shelf (ECS) of the United States. The ECS is that portion of the continental shelf beyond 200 nautical miles. It is an important maritime zone that holds many resources and vital habitats for marine life. Its size may exceed one million square kilometers, encompassing areas in the Arctic, Atlantic...

Researching seafloor mineral resources that occur within the U.S. Exclusive Economic Zone and areas beyond national jurisdictions.

Seafloor resource managers and modelers need seafloor maps that can be combined in GIS, modeling, and statistical analysis environments and related successfully to biologic and oceanographic data. The Marine Geomorphology, Evolution, and Habitats Project encompasses mapping activities and the development of new mapping systems and methodologies. The emphasis is on the role of geologic processes in...

The California Seafloor Mapping Program (CSMP) is a cooperative program to create a comprehensive coastal and marine geologic and habitat base map series for all of California's State waters.

Objectives: Produce a step-change in understanding of submarine turbidity currents by measuring their two key features (synchronous velocity and concentration profiles) in detail (every 2-to-30 seconds) for the first time, and documenting spatial changes in their flow velocity from source-to-sink for the first time.

EXPRESS is a multi-year, multi-institution cooperative research campaign in deep sea areas of California, Oregon, and Washington, including the continental shelf and slope. EXPRESS data and information are intended to guide wise use of living marine resources and habitats, inform ocean energy and mineral resource decisions, and improve offshore hazard assessments.

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, is one of three centers serving the mission of the USGS Coastal/Marine Hazards and Resources Program (CMHRP). Since its authorization by Congress in 1962, the CMHRP has served as the primary Federal program for marine geology and physical science research.

For our project, the R/V Marcus G. Langseth is towing a 12-kilometer-long hydrophone streamer that records sound reflected from deep below the seafloor , which is helping scientists image the structure of the Cascadia Subduction Zone and megathrust fault. The streamer records data as a function of the time it takes for sound to travel from the ship’s source down to “reflectors”

The USGS is working in partnership with the Bureau of Ocean Energy Management (BOEM) and the State of California Ocean Protection Council (OPC) to evaluate sand and gravel resources in Federal and State waters for potential use in future beach nourishment projects. Prior to the leasing and development of outer continental shelf (OCS) sand resources for use in beach restoration or coastal...

These field activity data releases, publications, and maps are part of the combined effort by the U.S. Geological Survey and NOAA’s Stellwagen Bank National Marine Sanctuary to map the geologic substrates of Stellwagen Bank and to study the ecology of fish and invertebrate species that inhabit the bank’s sandy substrates off Boston, Massachusetts.

From June 12 to July 3, 2019, the USGS sailed onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate fate in...

In the Field; Land, Sea, and Air Woods Hole Coastal and Marine Science Center scientists and staff study coastal and ocean resources and processes from the land, sea, and air, to shorelines and estuaries to the continental shelf, deep sea, lake floor, river bottoms and shallow subsurfaces environments. We have implemented new safety and fieldwork processes to maintain social distancing to ensure...
