Looking astern, the airgun sled is in its cradle in the center of the photo.  The crew are manually recovering the multichannel streamer and beginning the large figure-8 shape of coiling it on deck. Work at sea occurs 24 hours a day.  In late September, there is ~12 hours of night, resulting in gear recovery at night.

Science crew ran the multichannel seismic equipment, sonobuoy refraction equipment, navigation, marine mammal observations program, and incidental science studies.  Dr. Deborah Hutchinson (USGS liaison aboard the Canadian icebreaker) is 7^th from the right.  Dr. David Mosher, Chief Scientist aboard Louis is 10^th from the right.

Researchers have postulated that seafloor collapse or sediment failure could occur when certain drilling and extraction activities are conducted in deepwater marine environments where gas hydrates exist in the shallow sediments.  This schematic diagram, modified from Ruppel, Boswell, and Jones (2008), shows a compilation of other researchers

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 America and Alaska, which represent marine and permafrost-associated settings for gas hydrates, respectively.

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.

A pressurized, stable, hydrate-bearing sediment core can be fed through the IPTC body, shown here being used in Singapore to support the Indian National Gas Hydrates Program (NGHP1)
