Tripod deployment along the outer perimeter of Diamond Shoals, NC

Marinna Martini, Woods Hole, Coastal and Marine Science Center,  prepares to deploy tripods at three sites along the outer perimeter of Diamond Shoals, North Carolina. Mounted on the tripods were instruments to measure surface waves, pressure, current velocity, bottom turbulence, suspended-sediment profiles, and sea-floor sand-ripple bedforms; one tripod also held a visual

Static stress change models

Static stress change models for known or hypothesized faults in the Hispaniola and Puerto Rico subduction segments due to (a) slip on a patch of the Puerto Rico subduction zone, and (b) slip on a patch of the Hispaniola subduction zone. An open arrow denotes slip direction and the patches are marked by dashed rectangles. Heavy black lines are simplified fault traces.

Gas Hydrates Project personnel location map.

The USGS Gas Hydrates Project integrates across USGS mission areas, programs, and regions. The stars indicate the locations of personnel involved in the Gas Hydrates Project. Within the US, much of the research focuses on the Gulf of Mexico and Alaska, which represent marine and permafrost-associated settings for gas hydrates, respectively.
