Map of subsea permafrost distributions on the U.S. and Canadian Arctic Ocean margin. The inset map shows the location of the larger map. Subsea permafrost on the Canadian margin was delineated in the 1980s (blue curve). The red curve on the U.S.

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.

 USGS scientists built a model that reproduces the waves, currents (shown in meters per second [m/s]), and sand movement at Fire Island during Hurricane Sandy’s passage (Warner and others, 2017).

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.
