Map C.  Backscatter intensity and sun-illuminated topography.  Blue= "soft" seabed, Green, orange = "hard" seabed

Oblique aerial photographs of Hatteras Village, 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 cottage.

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.

Deployment period storm analysis. (A) significant wave height (red line) and wind speed and direction (arrows). Shading represents storm type (blue = cold front, red = warm front, yellow = low-pressure). (B) Vertical profiles of suspended-sediment concentration. (C) Cumulative along-shore and cross-shore sediment flux.

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.

Post Hurricane Irene: Beach state after Hurricane Irene showing the exposure of a groin from loss of beach elevation (foreground) and beach and dune scarping due to elevated water levels (background).

During Hurricane Irene, sand eroded from the beach and dunes was transported landward, burying a walkway near the Fire Island lighthouse.

U.S. Geological Survey geographer Nadine Golden (center, kneeling) works with USGS marine operations staffer Cordell Johnson (right) and a deckhand (left) to deploy a camera sled from the research vessel Coral Sea. The sled is towed close to the seafloor and collects real-time photographs and videos.
