(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.

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.
