Views of Cowells Beach in Santa Cruz, California, from a 10-minute video shot on May 6, 2017. Snapshot (first frame in video) on left; time-averaged image on right.

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.

Graphic showing geophysical and sampling systems used to define the seafloor topography, surface sediments, and underlying geology.

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.
