HLF-3 1981 Summer Tow Operations Report.
Abstract
Preparation and deployment of the HLF-3 acoustic source for 1981 summer tow operations is described. Preparation included preparation of a long (3000-foot) cable for towing the source, addition of a pneumatic compensation system and construction of a revised instrumentation system for deep towing. The source was towed in the Pacific for over 300 hours and generally performed well. The source was towed and operated briefly at 1380 feet submergence to test the modification, and operated well with a slight upward shift in frequency of peak output. (Author)
