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.

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.

The airgun sled is painted orange and suspended from the A-frame. The three airguns are suspended beneath the sled. The multichannel digital streamer (yellow cable going into the water from the sled) is towed from the the weighted sled to keep it under the ice. This photo shows the number of crew required to safely deploy the airgun sled.

A breach in the coastline of Rodanthe, North Carolina, caused by Hurricane Irene in 2011. Repeated storm impacts, combined with sea level rise, make the development and improvement of models that help forecast coastal change very important to planners working to build more resilient communities

Personal watercraft fitted with sonar and GPS were among the tools used by USGS scientists to map the bottom of shallow coastal waters near the mouth of the Elwha River. This shot was taken August 25, 2011, during a survey conducted just a few weeks before dam removal began.
