Abstract : The long term goals of our shallow water acoustics work were to: 1) understand the nature of low frequency (10-1500 Hz) acoustic propagation, scattering and noise in shallow water when strong oceanic variability is present in the form of fronts, eddies, boundary layers, and internal waves (using the SW06 and QPE data, primarily) and 2) initiate planning a 2016 bottom acoustics experiment in the MidAtlantic Bight and a 2017 field experiment to look at the complicated boundary between deep and shallow water, i.e. the slope/canyon region. Our primary objectives in the last year were to: 1) finish manuscripts on the QPE shallow water acoustics/Uncertainty work, and publish them in IEEE JOE, 2) begin 2016 (bottom acoustics) and 2017 (Arctic slope and canyon) experimental planning, both on an individual basis, and in conjunction with the whole ocean acoustics community, 3) continue work on modeling scattering by coastal internal waves and other features and 4) look at climate change effects in shallow water.
