Scripps Institution of Oceanography

Seismic refraction observations have been made by the staff of the Scripps Institution of Oceanography Marine Physical Laboratory in numerous locations in and near the Southern California Continental Borderland; many of these stations have not been reported previously. Travel-time plots, cruise notes, position data, and layer solutions for fifteen operations in the area (30 deg to 35 deg north latitude, from the coast west to l23 deg west longitude) provide the basic information for studies of crustal structure, and are presented here.
