Freely Drifting Swallow Float Array: Initial Estimates of Interelement Range.

Abstract

Self-contained, freely-drifting Swallow floats capable of recording very low frequency (VLF) ambient ocean noise are under development at the Marine Physical Laboratory, Scripps Institution of Oceanography, San Diego, California. The buoys are ballasted to neutral buoyancy at midwater depth where they record the components of particle velocity from which sound pressure levels may be derived. A high frequency acoustic mutual interrogation system is used to determine the buoys's relative position. Estimates of interelement range and buoy position have been made based upon acoustic positioning data taken during July 1983 west of San Diego.
