Abstract:

A coupled ocean mixed layer-acoustic model is evaluated in two dimensions at a line of stations in the northeast Pacific Ocean. The Oceanic Boundary Layer Model OBL is initialized using bathythermograph data acquired during the 1980 Storm Transfer and Response Experiment STREX. The OBL model was used to predict a new thermal profile after integrating in time for 20 days. This was then compared with actual bathythermograph data taken 20 days later. Three cases were examined initial, model, and final data as input to the RAYMODE acoustic model. The acoustic performance for the three cases was measured median detection range MDR and convergence zone range CRZ. In the absence of strong horizontal advection, over a 20 day period the OBL can predict surface temperature to within an average of 0.5 C. Therefore the coupled models can be used effectively to help predict MDR and CZR in a tactical situation. Keywords Oceanic mixed layer Coupled thermodynamic-acoustic model Theses.
