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).

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.

Authigenic carbonate supplies the foundation for deep-sea corals, including colonies of bubblegum corals (Paragorgia) seen here. 
 

(A) Maximum Likelihood Classification (MLC) with two inputs, slope, and ISO-classified backscatter for the whole survey area. (B) MLC with five inputs, slope, ISO-classified backscatter, bathymetry, hillshaded-relief, and curvature.

Time series of the coral reef at Grecian Rocks (Key Largo, FL) illustrating an example of the dramatic decline in live coral on Florida Keys reefs in recent decades. From Shinn and Kuffner (2017).

Paul’s Slide. Left: Air photo taken May 27, 2017, one of many that Beth Haddon will analyze with structure-from-motion software to measure changes in ground elevation. Right: Caltrans employees and contractors use an excavator and bulldozer to remove Paul’s Slide debris from California State Highway 1.

Tracklines along which R/V Ocean Starr (2017, red lines) and R/V Norseman (2016, black lines) conducted seismic-reflection surveys, overlaid on high-resolution bathymetry (color background). Yellow stars represent earthquakes of magnitude (M) 7 and greater since 1900.

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.
