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.
