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.

Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.

USGS Wetland and Aquatic Research Center's Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) outreach office staff were on hand at the World Wetlands Day celebration hosted by the Bayou Terrebonne Waterlife Museum and South Louisiana Wetlands Discovery Center as local students learned about the different types of wetlands in Louisiana.

Left: Key features in and around the Gulf of Alaska. A black rectangle outlines our 2016 study area along the Queen Charlotte-Fairweather fault. Red arrows indicate relative tectonic plate motions. Right: A shaded relief map of the 2016 study area. Rainbow colors show seafloor depths acquired by the USGS in 2015 and 2016. Red indicates shallower depths.

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.

Elizabeth Pendleton describes USGS work to map the Massachusetts seafloor to State Senator Viriato “Vinny” deMacedo.

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).
