Acoustic Tomography with Navy Sonars

Abstract

Utilize Navy sonars to map and understand temperature variability in ocean basins using acoustical tomography and hydrographic data. The data can be used to check and update ocean models for nowcasts and forecasts, and to check complimentary information from satellites. Most of the data come from U.S. submarines which tow arrays and measure temperature at 1-s intervals. Additional data come from the U.S. Navy's Sound Surveillance System (SOSUS). A principal objective of this grant is to show it is possible to use U.S. submarines to collect temperature and acoustical tomography data over basin-scales. A secondary objective is to show it possible to read existing Navy data tapes at SOSUS stations to process tomography signals from ATOC sources and sources deployed by Naval Air.
