A Moored System to Obtain High-Resolution Time Series of Velocity and Density in High Current Environments

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, because of the extreme currents and internal wave activity in the Strait, there has been little success in deploying a full-water column mooring in this region. The goal of this project is to obtain a 2-month time series of full water column velocity, density and turbulence in the heart of the Strait where internal tide generation is the most intense.
