Shipboard LADCP/chipod Profiling of Internal Wave Structure and Dissipation in the Luzon Strait

Abstract

We seek a more complete and fundamental understanding of the hierarchy of processes that transfer energy and momentum from large scales, feed the internal wave field, and ultimately dissipate through turbulence. This cascade impacts the acoustic, optical, and biogeochemical properties of the water column, and feeds back to alter the larger scale circulation. Studies within the Ocean Mixing Group at OSU emphasize observations, innovative sensor / instrumentation development and integration, and process-oriented internal wave and turbulence modeling for interpretation. Luzon Strait represents a major source of internal tides and NLIWs in the SCS. However, unlike other regions of strong internal wave generation (i.e., Hawaii), Luzon Strait is believed to be highly dissipative. We seek to understand the character of this enhanced nonlinearity and turbulence, and how it affects internal wave generation and transmission.
