Instrumentation for Upper Ocean Dynamics, Turbulence and Gas Transfer Research
Abstract
The long-term goal of this research is to understand the physics of upper ocean dynamics, turbulence, and gas transfer. The scientific objectives of this project are to use new technological advances in instrumentation to measure accurately the wavenumber-directional spectrum and its spatial and temporal variations; the velocity components over the full range of scales from large eddies on down to Kolmogorov micro-scale motions for turbulent kinetic energy properties in air and water; the eddy-correlation mass transfer velocities for gas transfer studies; and the radiative fluxes and turbulent flux-gradient relationships in air-sea interactions. The project also aims to gain further insight into the backscatter measurement of HF Doppler radars. We have acquired new instrumentation for use in air-sea interactions, ocean turbulence, gas transfer, and radar backscatter studies. Specifically, the new instrumentation will be used on the ONR-funded air-sea interaction spar (ASIS) buoys, on the Canadian SWATH ship "Frederick Creed," and in the DoD-funded air-sea interaction saltwater wind-wave tank (ASIST), which is currently being built at the Rosenstiel School of Marine and Atmospheric Science.
