The long-term goal is to understand and predict key properties of the signal intensity vector field as it propagates away from an active sound source with emphasis is on shallow water propagation. These properties are in turn determined by properties of the sea bed, the sea surface, and bathymetry. Advancement of current Navy capabilities will be in part realized through a better understanding of the environmental and acquisition geometry dependence source depth, range, etc. of the vector field in a shallow water environment. This year our objective has been to investigate properties of the acoustic vector field within a waveguide as they are influenced by the environment such as the time-varying sea surface and sloping bathymetry. The objective necessarily involves measurements from Targets and Reverberation Experiment TREX13 conducted in spring 2013.
