Map of study area: China Camp State Park and the adjacent shallows of San Pablo Bay. Black and gray bathymetry lines indicate the location of mean higher high water (MHHW) and mean lower low water (MLLW), respectively. Elevations in meters of those tidal datums are referenced to the North American Vertical Datum of 1988

Map of the North American West Coast, the monitored coastline is shown in light yellow. Dashed boxes delineate the different subregions of the study area. Pie charts show the regional distribution of advancing/retreating waterline trends during 2000–2022 derived from the dataset presented in this study.

Non-profit organizations Transom Story Lab and Atlantic Public Media hosted a weekend-long science storytelling workshop called "Making Waves." It was attended by 11 scientists from scientific institutions throughout Woods Hole, Massachusetts, including USGS scientists Jin-Si Over, Ellen Lalk, and Sara Zeigler.

An introductory course for small uncrewed aircraft system (sUAS) pilots was held at the New York State Emergency Preparedness Training Facility in Oriskany, New York. Instructors from across the country, including Sandy Brosnahan (lead instructor) and Seth Ackerman of the USGS WHCMSC, collaborated to deliver the training.

A seafloor mapping survey in Long Island Sound took place in May with collaborators from the University of Connecticut and the University of New Haven. They are mapping the area’s geology and biota to identify seasonal changes from their previous survey in November 2024.

USGS Coastal Change Likelihood (CCL) outcomes are displayed for Wallops Joint Expeditionary Base in Virginia. Warm colors indicate areas of high expected coastal change and cool colors indicate areas with lower expected change.

The Coastal Landscape Response assessment creates multidecadal predictions of where and when the coast is likely to adapt or inundate. Results are produced for four decades—the 2020s, 2030s, 2050s, and 2080s.
