NH1320 Seismic Reflection/Refraction

Seismic:Navigation

Seismic Navigation Data from the Newport Inglewood/Rose Canyon and Oceanside Blind Thrust fault systems, offshore California, acquired during the R/V New Horizon expedition NH1320 (2013)

This data set was acquired with a portable Multi-Channel Seismic system during R/V New Horizon expedition NH1320 conducted in 2013 (Chief Scientist: Dr. Graham Kent; Investigators: Dr. Neal Driscoll and Dr. Graham Kent). These data files are of U.K.O.O.A. P1/90 format and include Seismic Navigation data that were processed after data collection. Data were acquired as part of the project: San Onofre Nuclear Generating Station (SONGS) 2D Shallow Seismic Survey.
