Negative Potential Vorticity Generation in the Bottom Boundary Layer and Submesoscale Instabilities of the Boundary Current Along the Vietnamese Coast

Abstract

The Vietnamese East Sea is a complex body of water that is impacted by a variety of forcing on multiple temporal scales. During theNE monsoon, a 2000-km long boundary current links the inflow of Kuroshio water at Luzon Straits to the shelf and slope off Vietnam,also impacting the stratification and circulation on a basin-wide scale. The southward flowing boundary current is potentially unstable to a variety of submesoscale instabilities generated within the bottom boundary layer. We propose to examine the generation of negative potential vorticity, submesoscale instabilities, and enhanced turbulent mixing in the bottom boundary layer across the Vietnamese shelf, using a combination of glider-based endurance observations and coordinated ship- and glider-based process studies.
