Wide-angle seismic refraction navigation data (ASCII format) from the GUlf of Mexico Basin Opening (GUMBO) project (cruise IC1010, 2010)

This seismic navigation data set was acquired during an OBS refraction study of the deep crustal structure along the northern margin of the Gulf of Mexico. The fieldwork was conducted from October to December 2010 with M/V Iron Cat operated by Reservoir Geophysical under cruise ID IC1010, and chief scientists were Harm Van Avendonk and Gail Christeson. Four long-offset seismic refraction lines on the northern (U.S.) margin were collected. Airguns fired from the vessel were recorded on the seafloor by four-component ocean-bottom seismometers that had been supplied by the University of Texas Institute for Geophysics in Austin (UTIG) and by Geopro GmbH, Hamburg. The four seismic refraction lines all cross the margin from the shallow water near the coast to the deep water near the U.S.A.-Mexico maritime border. The data files are in ASCII format and were generated as part of the GUlf of Mexico Basin Opening (GUMBO) project.
