Ocean Acoustic Tomography with Moving Sources and Receivers
Abstract
The fundamental goal of the research performed under this contract has been to determine the precision with which the ocean mesoscale sound speed field can be measured using acoustic techniques. The basic idea is straightforward: to use acoustic sources and/or receivers suspended from ships to provide dense sets of acoustic ray paths in order to construct sound speed maps with mesoscale resolution over large areas. We named the technique Moving Ship Tomography. Determining the fraction of ocean sound speed variance that can be measured using acoustic techniques is of critical importance in potential applications to passive and active ASW systems. The ocean sound speed field is required as input for matched field (and other) processing of long range acoustic transmissions. The ability to measure the ocean sound speed (temperature) field with mesoscale resolution is also important to the study of eddy kinematics and dynamics, to verify numerical models, and to study data assimilation techniques.
