Linked Physical Oceanography and Acoustics Studies at Atlantis II Seamounts

Abstract

A project linking underwater acoustic behavior analysis, ocean modeling and prediction, and field studies of underwater sound is pro,posed as part of the ONR Task Force Ocean DRI program centered at the New England Seamounts. The ocean flow and water mass features,have high variability in this area due to high energies and accelerations of the Gulf Stream, energetic eddies, adjacent water masse,s of differing density (responsible for high available potential energy), strong and cold winter forcing, tropical cyclones, and sea,sonal strong storms. Furthermore, the variable slopes and seabed types at the seamounts may cause wide variations of the bottom-inte,racting sound. The present-time ability to know patterns of sound-field variation in the area, with or without direct measurements b,y acoustics systems in the area, will be evaluated, as well as a prediction horizon time estimate. A nested suite of ocean models of, the area will be used for the study, with the models integrated with acoustic field computational modeling. Finally, a towed-source, in situ sound field study comparing predicted to observed acoustic fields will be made as part of a multi-PI field study. Both the,modeling and the field work will be performed with collaborating partners.
