The USGS partnered with North Carolina State University, Louisiana State University, and University Corporation for Atmospheric Research to investigate hurricane-induced compound flooding and sediment dispersal using coupled hydrology and ocean models.

Where are coastal landscapes likely to change?

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

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 assessment integrates data describing coastal characteristics, landscape composition, and the level of resistance to change to produce the initial fabric layer. 

Data defining the drivers of change that impact the coast, such as waves and flooding are synthesized in hazards layers.

The CCL assessment integrates data describing coastal characteristics, landscape composition, and the level of resistance to change, with data defining the drivers of change that impact the coast, such as waves and flooding. These data types are known as fabric and hazards, respectively.

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 2023 annual report of the U.S. Geological Survey Woods Hole Coastal and Marine Science Center highlights accomplishments of 2023, includes a list of 2023 publications, and summarizes the work of the center, as well as the work of each of its science groups.

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. 

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.
