A Comparison of Velocity Profiles Obtained from an Expendable Temperature and Velocity Profiler (XTVP) and a Acoustically Tracked Profiler at the Atlantic Underwater Test and Evaluation Center (AUTEC),

Abstract

A series of nearly simultaneous drops of two velocity profilers was made at the Atlantic Underwater Test and Evaluation Center (AUTEC). One profiling method was based on the measurement of motionally induced electric currents by an expendable device. This profiler, the Expendable Temperature and Velocity Profiler (XTVP), was compared with an acoustically tracked free-fall device operated by personnel of the Johns Hopkins University's Applied Physics Laboratory. Based on drops separated by less than 100m horizontally and about 50 minutes in time, the two sets of profiles were found to agree within about 1 cm/s rms for east and north horizontal velocity components.
