Purpose
To obtain detailed geophysical data between Cape San Martin and Pt. Sal
that would aid in identifying lithologic units and interpreting offshore
geologic structure for the evaluation of potential hazards, if any, to large
coastal installations and attendant offshore pipelines. Potential hazards may
include such features as faults that cut the seafloor, areas of landsliding, and
submarine slumping.
Information to be Derived
Approximately 750 mi (1200 km) of deep penetration single channel
seismic records were obtained using a 120,000 joule sub-bottom acoustic
reflection profiling system with a 3-second sweep; hight resolution records were
run simultaneously using an electrical-mechanical system with a 1/4 second
sweep. Bathymetric data were obtained with a precision depth recorder, magnetic
data were gathered with a ship-towed magnetometer, and side-scan sonar records
wers taken locally. The track lines extended 6 to 10 mi from shore and were
spaced one nautical mile apart throughout most of the area. Because of
structural complications offshore from the Diablo Canyon site, another 80 mi
(130 km) of geophysical line was run in that area December 1973, by Geomarine
Services under contract to the Pacific Gas and Electric Company.
