Beschreibung:
Time series of currents were obtained in the period October 2013 and May 2014 by use of an ice-tethered mooring in Young Sound, Greenland. At YS02 (74.267o N, 20.248o W) the mooring consisted of a 300 kHz downward-looking Teledyne RDI Workhorse Sentinel acoustic Doppler current profiler (ADCP) measuring horizontal and vertical current velocities. Velocity precision and resolution were ±1% and ±5 cm s-1, respectively, while compass accuracy and resolution were ±2 and 0.1 degrees. The ADCP was set to sample 39 bins (bin size of 2m), where each 10 min sample consists of averages of 20 pings. The first and last bins were set at 6 and 84 m depth. Velocities were corrected for magnetic deviation (18.5 degrees) and samples with insufficient acoustic backscatter in the water column were eliminated with the RDI ADCP software.

Shelf Sci., 15, 194-205. https://doi.org/10.1016/j.ecss.2017.06.021).
