Velocity model navigation files (ASCII format) for the Chicxulub Crater area (96L676, 1996)

This data set presents the navigation data for two-dimensional seismic P-wave velocity models are derived from inversion of ocean bottom and land seismic data collected in the Chicxulub Crater area during 1996 R/V Longhorn cruise 96L676. A second vessel, GECO Sigma, fired airguns to the OBS and land seismometer instruments. The velocity model navigation files are in ASCII format and relate the model distance to (latitude, longitude) coordinates. The files contain three columns: Model distance along the profile (km); Latitude (degrees); Longitude (degrees). The data set was generated as part of the project called Structure of the Chicxulub KT Impact Crater, Yucatan, Gulf of Mexico, with funding from NSF award OCE94-15716.
