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 output 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 using median detection range (MDR) and convergence zone range (CZR). 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 4be used effectively to help predict MDR and CZR in a tactical situation.
