HLF-3 Tow Services.

Abstract

The HLF-3 acoustic source was built by Hydroacoustics Inc. to use in acoustic propagation measurements. In 1977 the source was used in an extended sea test (PANOIC) in the Pacific. The source performed well, logging over 466 hours of operation in that test. However, there were a few failures that caused some loss of operating time. The present contract deals with design improvements to eliminate those faults plus support for two more installations and tows and the purchase of 3000-feet tow cable for the source.
