Description

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 (1) achieving improved imaging and characterization at two
established gas hydrate study sites, and (2) refining geophysical methods for gas hydrate
characterization in other locations. We conducted this acquisition aboard the R/V Pelican, and used a
pair of 105/105-cubic-inch generator/injector air guns to provide seismic energy that we recorded using
a 450-meter 72-channel digital hydrophone streamer and 25 multicomponent ocean-bottom
seismometers.
