Abstract:

LONG-TERM GOAL. We wish to improve our suite of instrumentation to measure upper ocean dynamics, turbulence, gas transfer and recording and computing equipment for data acquisition and real-time processing of data. SCIENTIFIC OBJECTIVES. To measure high frequency turbulence and wave velocities with velocimeter instruments such as acoustic doppler velocimeter ADV and velocity-density-vorticity VDV. To measure accurately the wavenumber-directional spectrum, and its spatial and temporal variation with laser ranging gauges. To measure the pressure above the waves, a key to understanding the wave generation problem on the ocean with sensitive MKS pressure transducers and Elliott pressure probes. To use hot wirefilm anemometry to resolve velocity components over the full range of scales -- from the large eddies to the Kolmogorov micro-scale. Modern constant temperature anemometer CTA systems are extensively used in gas transfer studies and investigations of turbulent kinetic energy properties in both phases air and water and in both environments laboratory and field. To measure also temperature fluctuations with a constant current anemometer CCA module. To measure the necessary corrections for the motion of the buoy with 6-degree of freedom inertial packages.
