Shipboard Acoustic Current Profiling during the Coastal Ocean Dynamics Experiment,

Abstract

The shipboard Doppler Acoustic Log (DAL) discussed in this study is a new tool for the measurement of ocean currents. By providing vertical profiles of currents over the upper 150m of ocean at points along the ship's path, it allows the ocean to be sampled in a way which is fundamentally different from moored current meters or drifters, the instruments most commonly used for current measurement. This instrument is used to examine the circulation in a region of strong coastal upwelling off Northern California, where it reveals an unexpectedly energetic and spatially complex synoptic flow field.
