Low Frequency Acoustics

Abstract

LONG-TERM GOALS. The long-term goal is to improve understanding of very low frequency (VLF) acoustics in the deep ocean as applicable to naval warfare and coexistence with marine mammals. OBJECTIVES. The primary objectives of the project were to: (1) initiate implementation of an acoustic data recovery capability; (2) evaluate very low frequency noise characteristics in the deep ocean; (3) encourage a cooperative interagency working relationship to investigate acoustic impact on marine mammals; and (4) declassify ocean acoustic information produced under a Navy project during the Cold War. APPROACH. Objectives (1) and (2) were addressed cooperatively with the Applied Research Laboratories of the University of Texas (ARL:UT). Dr. David Knobles was the Principal Investigator for acoustic analysis and Jack Shooter was in charge of development of the data recovery process at ARL:UT. The interagency liaison and document declassification tasks were spearheaded by Dr. Roy Gaul.
