Purpose
|
To provide a better understanding of the geologic history of the
Continental Borderland off the coast of southern California.
|
|
|
Information to be Derived
|
750- to 3,000-joule high resolution detailed seismic reflection
profiles seaward of two favorable areas, Eel and Lost Points, on the western
side of San Clemente Island. Sampling of sediments at depths greater than 45 m.
|
|
|
Summary
|
Detailed survey off Eel and Lost Points. 59 survey lines plus 8 north
of Eel Point. Most data good. Eel Point profiles too highly exaggerated.68
samples collected.
|
|
|
Notes
|
CURV vehicle of Naval Undersea Research and Development Center, was
also used for seafloor sampling.
