Combining Acoustic, In-Situ, and Remotely-Sensed Data with Regional Ocean Models in the East China and Philippine Seas
Abstract
The long-term scientific objective of the Quantifying, Predicting, and Exploiting (QPE) Uncertainty Directed Research Initiative (DRI) is to improve the assessment of uncertainty in observations and predictions of sound propagation in littoral regions. The objectives of this research are to understand and exploit the effects of the ocean state on acoustic propagation and detection. This work will contribute to the goals through global and regional physical ocean modeling and data assimilation. The modeling includes both model comparisons with observations, evaluating model error, and forecast and predictability studies to see the growth of uncertainty in time and space and the influences of the past ocean state on the acoustic propagation conditions on the shelf north of Taiwan. The QPE DRI is a coordinated effort in which many types of measurements have been collected over the continental shelf to the north of Taiwan. The field results will be used to help characterize the rapidly varying physical environment in comparison to the models and to study acoustic propagation and scattering in the region. Two of the most important physical processes in the region of the experiment are the cold dome observed off the northwest corner of Taiwan and intrusions of the Kuroshio onto the shelf north of Taiwan.
