Input files for a seismic velocity model of the Australian-Antarctic Discordance (AAD) region of the Southeast Indian Ridge (investigator Chad Holmes)

This data set contains seismic velocity model input and parameter files that were used in the seismic velocity models published in Holmes et al. (2010). The files are of ASCII format in a TAR bundle and include information on source-receiver geometry, weighting factor, analysis limit, Moho reflector depth, and ray paths. An included README document describes the contents of each file. The 2-D seismic velocity models were derived from OBS/OBH refraction data collected along four lines using airgun shots fired during cruise WEST08MV and were parameterized by a dense nodal mesh draped on the bathymetry combined with independent depth nodes for the Moho. These data files were generated as part of the project called "A Seismic Refraction Investigation of Crustal Thickness Variations between the Australian-Antarctic Discordance and the Neighboring Southeast Indian Ridge: Data Analysis" with funding provided by NSF grant 97-96101.
