In-Situ Oceanic Turbulence Measurements Using a Mobile AUV Platform

摘要

A turbulence measurement mission in up to 150m deep waters, using Florida Atlantic University's small autonomous underwater vehicle (AUV), the Ocean Explorer, is described. The gathered data includes measurements of current profiles using an on-board ADCP, CTD measurements and in-situ small-scale turbulence measurements using shear probes. During our first mission in winter 1996 in 18m deep waters in an inlet near Boca Raton, we were able to make superior quality turbulence measurements (reported elsewhere) corresponding to energy dissipation rates in the range ε= O(10~(-8) - 10~(-9))W/kg. Here we describe similar quality measurements in a Gulf Stream mission at depths of 126m during summer 1997.
