Worldwide distribution of observed and inferred gas hydrates in marine and permafrost-associated settings that have been the subject of drilling programs. The color coding refers to the primary sediment type in each location and therefore designates the likely type of gas hydrate reservoir at each site.

Bird's-eye view map of a section of the seafloor off southern California, made with depth data. The map shows a channel wall that has been cut by the San Diego Trough fault and moved about 20 meters. This feature is about 1,000 meters below sea level.

Oblique aerial photographs of Ocracoke Island, NC, from May 6, 2008 (top, pre-storm) and August 30, 2011 (bottom, post-storm, acquired three days after landfall of Hurricane Irene). The yellow arrow in each image points to the same feature. Overwash deposits of sand extend over the road after the storm.

USGS Pacific Coastal and Marine Science Center's research vessel R/V Parke Sanvely motors through Alviso Slough in the southern end of San Francisco Bay. Scientists were collecting depth data to make a detailed bathymetric map of the Bay.

Steaming to the deployment site south of Martha's Vineyard, MA in 2011. The platform shown was specially adapted so the arm cycles up and down through the Benthic Boubdary Layer while deployed on the seafloor.  For more information see https://soundwaves.usgs.gov/2011/11/fieldwork2.html.

USGS scientists test the moving arm bottom platform at the Woods Hole Oceanographic Institution (WHOI) dock.  While it was deployed, the system moved sensors through the bottom boundary layer and transmitted data in real time to shore via WHOI's Martha's Vineyard coastal observatory.

USGS scientists assembling a novel profiling arm to measure suspended sediment in the benthic boundary layer. This large seafloor platform was later deployed for several months off Martha's Vineyard, MA as part of the Optics Acoustics and Stress In Situ (OASIS) Project in 2011.
