SW06 Data Analysis, Slope-Canyon Experiment Planning, and Long-Range Sound Propagation with Applications to the Arctic

The long term goals of our shallow water acoustics work are to: 1) understand the nature of low frequency (10-1500 Hz) acoustic propagation and scattering in shallow water when strong oceanic variability is present in the form of fronts, eddies, boundary layers, and internal waves and 2) begin plann...

Description
Summary:The long term goals of our shallow water acoustics work are to: 1) understand the nature of low frequency (10-1500 Hz) acoustic propagation and scattering in shallow water when strong oceanic variability is present in the form of fronts, eddies, boundary layers, and internal waves and 2) begin planning a 2016 field experiment to look at the complicated boundary between deep and shallow water, i.e. the slope/canyon region. Our primary objectives this year were: 1) to continue the analysis of the vast data set collected by the SW06 experiment, model it with theory and numerical models, and publish the results in a JASA Special Issue. 3-D acoustics and oceanographic effects were of particular interest. 2) Begin 2016 experimental planning, both on an individual basis, and in conjunction with the whole ocean acoustics community.
