Purpose
|
PURPOSE:
A. Collect geological information on types and sources of sediment deposited
on the inshore continental shelf off Oregon in connection with the exploration
for heavy metals.
B. Obtain sparker and airgun sub-bottom profiles in selected areas.
C. Obtain grab samples from selected stations.
D. Collect bathymetric data in areas of interest.
|
|
|
Information to be Derived
|
Seismic reflection profiles, bathymetry.

Summary

Summary
Sparker tracks were run using two electrode cages, arcing in unison,
and separated by a distance of 30 feet. Small depressers attached to the
cages were, in the course of the cruise, added to keep the electrodes in
the water (approximately 15 feet) at higher speeds (up to 10k). The
sparker tracks were conducted at varying speeds throughout the cruise
depending on the nature of the bottom and the performance of equipment.
A total of 92 samples were obtained with a shipek grab sampler in the
course of this cruise.
Bathymetric records were made concurrent with all sparker tracks.
The magnetometer proved unreliable on all tests and its use was subsequently
discontinued.
Position fixes were obtained primarily with the Decca, Model TM629, radar.
About 1800 nautical miles were covered in the course of the cruise.
