Seismic P-wave velocity model (netCDF format) from GUMBO line 4, Gulf of Mexico (2010, IC1010)

This data set was generated as part of the 2010 GUlf of Mexico Basin Opening (GUMBO) program that collected wide-angle seismic refraction profiles in the northern Gulf of Mexico to better constrain crustal structure in the region.This data set presents the seismic P-wave velocity model for the eastern profile, GUMBO line 4, which extends for a distance of 507 km from offshore northwestern Florida, across the continental shelf and Florida Escarpment, and into the central Gulf of Mexico. The velocity model is in GMT-compatible netCDF grid format. The x-coordinate is profile distance in km (grid interval 0.2 km), the y-coordinate is depth in km (grid interval 0.1 km), and the z-values are P-wave velocities in km/s. The GUMBO seismic refraction survey was conducted during late 2010 using M/V Iron Cat operated by Reservoir Geophysical. The project was funded through ExxonMobil.
