Predictability of Short-Period Variability in the Philippine Sea and the Influence of Such Variability on Long-Range Acoustic Propagation

Abstract

This work aims to determine the extent to which models of ocean variability can be used for the study of long-range acoustics. Models of ocean variability in the Philippine Sea are to be developed from historical data and from the PhilSea'09 and PhilSea'10 experiments. These models will then be used to obtain the relevant acoustic properties (e.g., full-depth sections of sound speed) such that the effects of variability on long-range acoustic propagation can be calculated and compared to field data. Another objective is to examine data obtained on deep hydrophone arrays during the SPICEX experiment to establish general properties of receptions that occur in the shadow zone.
