San Francisco Bay Bathymetry

Bathymetry of a dynamic tidal estuary, such as San Francisco Bay, provides the observable linkage between anthropogenic modifications of the landscape—such as evolving land use practices, flood control, and water diversions—and natural forces of climate-driven river flow, sea level change, tides, and wind. By examining our record of hydrographic surveys, spanning over 150 years, we can gain...

Climate impacts on Monterey Bay area beaches

For beach towns around Monterey Bay, preserving the beaches by mitigating coastal erosion is vital. Surveys conducted now and regularly in the future will help scientists understand the short- and long-term impacts of climate change, El Niño years, and sea-level rise on a populated and vulnerable coastline.

Massachusetts Integrated Coastal Studies (MICS)

Coastal erosion, intense storm events and sea-level rise pose threats to coastal communities and infrastructure. Managers and scientists often lack the high-resolution data needed to improve estimates of sediment abundance and movement, shoreline change, and seabed characteristics that influence coastal vulnerability. To address these and other needs the U.S. Geological Survey, in partnership...

Using Video Imagery to Study Marconi Beach

Two video cameras are mounted on a bluff above Marconi Beach, Cape Cod National Seashore, Wellfleet, MA. One camera looks alongshore toward the northeast, and the second looks directly offshore (east). The cameras are part of a U.S. Geological Survey research project to study the beach and nearshore environment shared by beachgoers, shorebirds, seals, and sharks. The work is being conducted...

Stellwagen Bank National Marine Sanctuary Geologic Mapping

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.
