Deep submergence research conducted during the period 1 January through 31 December 1965

Abstract

The Deep Submergence Research Program at Woods Hole Oceanographic Institution (WHOI) made progress during this period by demonstrating an operational deep diving (6000 feet) research submarine after an extensive testing period. The 96' long catamaran tender was completed and successfully used to support the diving operations and provided repair facilities for the submarine overseas. A major submarine modification program was carried out last winter at Otis AFB and completed at Cape Kennedy prior to shallow water testing. The catamaran was towed to Port Canaveral and there was outfitted for sea. Submarine launching and recovery procedures were worked out with a dummy ALVIN. The catamaran with ALVIN on board was towed to Coral Harbour, Bahamas, where 7500 foot unmanned and 6000 foot manned test dives were conducted following shallower testing. Operations were then moved to Bermuda after a short stay in Port Canaveral for repairs. In Bermuda several deep dives were made prior to termination by worsening weather. Two shallow scientific dives in the Woods Hole area were made before weather cancelled plans to make a geologic dive into Hydrographers Canyon. The submarine was then moved again to Otis AFB for annual inspection and minor repairs and modifications. The catamaran was placed in a Boston Shipyard for major modifications prior to deployment to the Bahamas in early 1966 for a scientific diving program. A summary of the dives is included and additional technical reports are referenced.
