Acquisition of high resolution 5-beam ADCPS for the Inner shelf DRI

Abstract

Abstract The inner shelf is a region of variable stratification and wind stress, with flows dependent on a variety of physical mechanisms occurring both in regions deeper and shallower than the inner shelf. Here surface and bottom boundary layers at times overlap, complicating simple physical models appropriate for the outer shelf that distinguish between distinct turbulent boundary layers and a more quiescent interior. Turbulence, both in boundary layers and in the stratified water in between, is crucial for 1) transmitting momentum vertically through turbulent stresses (e.g. determining how much and when wind-driven flows ``feel" the bottom), and 2) producing turbulent fluxes of heat, freshwater, pollutants and biologically essential nutrients. Here we propose to purchase five innovative new 5-beam ADCPs, along with requisite bottom tripods and mounting hardware, ideally for use as part of the “Inner Shelf” DRI. With the purchase of the proposed instrumentation, the goals of the proposed work are to: * Understand the processes driving turbulent vertical/diapycnal mixing throughout the inner shelf, with an emphasis on the stratified water that exists between surface and bottom boundary layers; * Consider the implications of that turbulence for regional heat and momentum budgets, and *Develop physically accurate parameterizations of turbulent mixing and transports appropriate for the unique inner shelf environment
