NH1323 Seismic Reflection/Refraction

Seismic:Reflection:MCS

Raw Multi-Channel Seismic Shot Data from offshore southern California, between San Clemente and Oceanside, acquired during the R/V New Horizon expedition NH1323 (2013)

This data set was acquired with a Multi-Channel Seismic system during R/V New Horizon expedition NH1323 conducted in 2013 (Chief Scientist: Dr. Neal Driscoll; Investigators: Dr. Neal Driscoll and Dr. Graham Kent). These data files are of SEGY format and include Multi-Channel Seismic Reflection shot data that have not been processed. Data were acquired as part of the project: San Onofre Nuclear Generating Station (SONGS) 3D Shallow Seismic Survey.
