Photograph of Carmel River near the Sleepy Hollow reach. San Clemente Dam was built on Carmel River in 1921 to supply water locally. After being declared seismically unfit, plans to remove the dam began. It was completely removed in 2015.

Photo shows results of wave-driven flooding and overwash on Roi-Namur Atoll, Republic of the Marshall Islands.

Map showing the amount of sea-level rise that will double the chances of today’s “50-year floods,” which have a 2 percent chance of happening in any year. Warmer colors indicate areas at greater risk.

Orthomosaic images of Matanzas, Florida, from (a) before and (b) after Hurricane Matthew, and (c) a digital elevation model (DEM) showing the associated topographic change. Note, these results were produced by applying Structure-from-Motion (SfM) to NOAA oblique photographs, but similar results can be obtained using UAS aerial imagery.

Perspective views of multibeam bathymetry data acquired by the USGS aboard the R/V Medeia. Shallower depths in red. Arrows point to the distinct line in the seafloor associated with the Queen Charlotte-Fairweather fault.

A look into the USGS Pacific Coastal and Marine Science Center’s Marine Minerals Laboratory Suite.

Members of the PCMSC Marine Minerals Team, including physical science technician Kira Mizell (center), took turns describing the importance of seafloor minerals.

A series of images from various sources of shaded-relief topography show the progression of the Mud Creek landslide area, from 2010 through October 12, 2017.

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.
