The U.S. Geological Survey, in cooperation with the National Park Service, developed the Coastal Change Likelihood assessment to determine the future likelihood of coastal change along the Northeast U.S. coastline in the next decade. Here is the CCL map for Chesapeake, Va.

The CCL is an updated version of the older Coastal Vulnerability Index, first published in 1999. While the original product was focused on change in the next 50-100 years based solely on sea level rise, the new CCL is more near-term, focusing on change over the next decade as a result of multiple coastal hazards.

The CCL data displayed here are for the mid-Atlantic Bight, and extend from the shoreline to 10m elevation inland.

The year of 2022 was big for the Sea-Floor Mapping Group at the Woods Hole Coastal and Marine Science Center! These data were collected as part of a collaborative research program and include data collected by USGS and our partners.

The 2022 annual report of the U.S. Geological Survey Woods Hole Coastal and Marine Science Center highlights accomplishments of 2022, includes a list of 2022 publications, and summarizes the work of the center, as well as the work of each of its science groups.

USGS scientists working on FLACC study coastal change, and develop techniques and metrics to measure past, present, and future shoreline change rates along the sandy coasts of the U.S.

USGS scientists collect core samples from marsh to explore the drives of wetland accretion in the face of rising seas and human impacts impact the evolution on salt marshes.

As sea levels rise, salt water extends further up tidal rivers. As sea-level rise accelerates, vegetation transitions are increasingly observed and USGS scientists are busy assessing those changes. USGS scientists take soil cores in the marsh.

In collaboration with Massachusetts Coastal Zone Management Agency (MCZM), SFMG completed a geophysical survey (multibeam echosounder and chirp seismic survey) within Nantucket Sound to characterize the seafloor surface and subsurface. The effort extended coverage in Nantucket Sound along the southern shore of Upper Cape Co

The San Andreas fault in California is shown in green, and the Cascadia Subduction Zone north of it is shown in yellow. The animation ends at the location of Queen Charlotte-Fairweather fault (in yellow), displaying the latest 30-meter terrain model.
