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 goal of this research is to understand and exploit the effects of the ocean state on acoustic propagation and detection. This work will contribute to that goal through regional ocean modeling and data assimilation. The modeling will include forecast and predictability studies to see the growth of uncertainty in time and space and the predictability of the propagation conditions on the shelf north of Taiwan from the ocean state. 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 and to study acoustic propagation and scattering in the region. The technical approach centers on using the Frechet derivative (adjoint) of a regional ocean model to explore the sensitivity of critical environmental features of the shelf region to the ocean in the region, to forcing, and to boundary conditions.
