Maps of five study sites spread across the conterminous United States, Alaska, and the Island of Puerto Rico and descriptions of each site’s coastal setting. From the study Comparisons of Shoreline Positions from Satellite-Derived and Traditional Field- and Remote-Sensing Techniques.

In Fall 2025 the Hawaiʻi Abyssal Nodules and Associated Ecosystems Expedition, led by USGS scientists, will investigate the geology, minerals, and environmental setting of the deep seabed offshore Moku o Keawe (Hawaiʻi Island) in the U.S. Exclusive Economic Zone. This work is part of ongoing collaborative efforts with BOEM and NOAA.

To assess our #sedimenttransport prediction techniques, #USGS scientists deployed a high-tech instrument off #SandyNeckBeach in Barnstable, Massachusetts from March-April 2021 to measure water velocity, temperature, and salinity, wave pressure, tidal force, seabed changes, and sediment characteristics. 

The USGS uses a nationwide network of coastal observing cameras (CoastCams) to monitor coastal conditions in near real-time and support research on a variety of coastal processes and hazards.

A new study introduces a cutting-edge biogeomorphic model (UBMorph) to help predict how #ChesapeakeBay #saltmarshes will change over time. Using UBMorph, researchers found that 404 square kilometers (37%) of vegetated #marsh area in Chesapeake Bay could be lost by 2110.

A new #datarelease contains a GIS compilation of vector shorelines and associated #shorelinechange data from the 1800s to the 2010s for the coast of Long Island Sound, #NewYork and #Connecticut. 

The Autonomous MAPping CATaraft, or “Autonomous MAPCAT”, is a remotely controlled, 14 foot long by 7 foot wide boat, built from an inflatable pontoon, aluminum frame, whitewater cataraft.

Brita Jessen at the 2025 Woods Hole Science Stroll on August 9, 2025. During this free event, a variety of booths line the streets, docks, and Waterfront Park to deliver hands-on science activities, games, demonstrations, and more to visitors of all ages. 

Checking out one of our drones! The Aerial Imaging and Mapping Group showcased uncrewed aircraft system technology (drones) of all sizes and talked about how they’re used to map short- and long-term changes in coastal landscapes. The group also flew one of the drones to demonstrate how they’re piloted.

Meagan Eagle used a gas analyzer and respiration chamber to demonstrate the role of salt marshes in carbon sequestration.
