Description:
Horizontal ocean currents were measured from drifting sea ice, using an RD-Instruments 75 kHz ADCP (acoustic Doppler current profiler), Longranger, deployed pointing downward through an hydrohole on ice for all three drifts of the MOSAiC expedition between 30 November 2019 and 19 September 2020. Due to the unreliability of magnetic compasses at high latitudes, a GPS compass was used and the current profiles were recorded in beam coordinates. Geo-referenced, eastward and northward velocity components in the upper 500 m were obtained during post processing.
