Acoustic Seaglider: Philippine Sea Experiment

Abstract

Abstract : Within the Ocean Acoustics Deep Water program, the long-term goals are to understand the physics of long-range, broadband propagation in deep water and the effect of oceanic variability on acoustic propagation. The project will seek to develop new techniques and technologies to improve the ability to measure and characterize the highly dynamic ocean environment and understand the effect of ocean variability due to mesoscale eddies, tides, currents, and internal waves on the acoustics. An accurate characterization of the ocean improves the predictability of acoustic propagation through it and, in turn, enables inversions for oceanic properties from acoustic receptions. The long-term goal is to use multiple platforms and techniques, old and new, acoustic and oceanographic, moored and mobile, to sense the ocean environment, and to understand the effect of oceanic fluctuations on deep-water acoustic propagation.
