Shipboard LADCP/(chi)pod Profiling of Internal Wave Structure and Dissipation in the Luzon Strait

Abstract

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. In 2010 & 2011 we deployed 5 moorings (locations indicated at right in red) and executed detailed shipboard campaigns to: identify hotspots of generation and dissipation, quantify the structure and variability of wave energy, its flux and dissipation at the generation site. link the broader spatial structure, temporal content, and energetics of the internal wave field to the topography, forcing, and mesoscale influences (i.e., Kuroshio). DISTRIBUTION STATEMENT A. Approved for public release; distribution is unlimited.
