Information to be Derived: Seismic reflection profiles, bathymetry.
Summary of Activity and Data Gathered: physical data holdings 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.
