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.

Ice-like gas hydrates under capping rock encrusted with mussels on the sea floor of the northern Gulf of America.

USGS pilot Sandy Brosnahan and Senate Pro Tempore Marc Pacheco discuss the use of Umanned Aerial Systems (UASs, also known as drones) to collect data in coastal environments.

(Top) Methane plumes at the Norfolk Canyon seeps (~1600 meters or 5250 feet) were detected using the EK60 sonar. The water column plumes are shown above the sub-seafloor structure as imaged by high-resolution multichannel seismic data acquired by the USGS and processed by J. Kluesner.

Methane bubbles emerging from the seafloor at a seep site colonized by chemosynthetic mussels at ~1000 m water depth on the Virginia margin. Photograph taken by the Global Explorer operated by Oceaneering Inc.

USGS ocean engineers Peter Dal Ferro and Gerry Hatcher, from the Pacific Coastal and Marine Science Center in Santa Cruz, California, deploying a multicorer to sample the seafloor near an Atlantic margin methane seep site.

It's a bird? It's a plane? It's a drone! USGS drone pilot Emily Sturdivant (seated) demonstrates flying an Unmanned Aircraft System (UAS), much to the delight of the onlookers.

Hill-shaded bathymetric, backscatter, and photographic data collected by NOAA and the USGS. Backscatter data give indications of seafloor character. In general, low-backscatter intensity (blue) corresponds to finer-grained material, whereas high-backscatter intensity (orange) corresponds to coarser substrate.

The USGS conducted surveys on the inner continental shelf of the Delmarva Peninsula (shown in green) to complement related datasets previously collected in the area by partners NOAA and BOEM. The inset map shows location of the study area.
