Modeling and Measuring Variability in 3-D Acoustic Normal Mode Propagation in Shallow Water Near Ocean Fronts Using Fixed and Moving Sources and Receivers

Abstract

The long term goals of our research are to: 1. Understand and model the 3-D propagation effects in shallow water and thereby explain some of the variations in acoustic field produced by the presence of shelf-break fronts and internal waves. 2. Apply our long range tomography inversion technique different locations and using different sources and improve the mode arrival estimation to improve it. 3. Explore the possibility of using underwater gliders as acoustic receive platforms and develop processing techniques for data collected using them. 4. Revisit an earlier study to look into sea surface wave effects on modal travel times.
