Abstract/Summary

We present acoustic correlation current profiler (ACCP) data collected during Discovery cruise 223 and analyse its performance, in terms of %good, depth penetration, standard deviation of velocity per time / depth bin, as a function of various other parameters: wind speed, significant wave height, relative wind direction and ship speed. We compare ACCP currents with currents measured at the same time by acoustic Doppler current profilers (ADCPs), both vessel-mounted (VM-ADCP) and lowered (L-ADCP). Mainly the results are disappointing: the ACCP routinely profiles down only to about 600 m; there is near-zero data return in poor weather (moderate to high winds and waves); even deep profiles, down to ca. 1500 m on station in calm weather show much scatter and some divergence from L-ADCP profiles.
