The U.S. Geological Survey led a seismic acquisition cruise in the Gulf of Mexico from April 18 to May 3, 2013, with the objectives of achieving improved imaging and characterization of Terrebonne and refining geophysical methods for gas hydrate characterization in other locations. They conducted this acquisition aboard the RV Pelican, and used a pair of 105-cubic-inch generator and injector air guns to provide seismic energy that we recorded using a 450-meter 72-channel digital hydrophone streamer.
