| contents | Ocean current velocity profiles were collected from drifting ice floes in the marginal ice zone northwest of Svalbard during RV Polarstern expedition PS131 (ATWAICE) using a Teledyne RDI 300 kHz Workhorse Acoustic Doppler Current Profiler (ADCP, serial number 15085). The aim of this expedition was to investigate sea ice summer melt processes, with a focus on the contribution of the Atlantic water inflow into the region. The ADCP was installed in a standard in-line frame attached to a pole, and suspended below the sea ice base through a hole in ice. In total, ten datasets of several hours of ocean current velocity profiles were obtained during repeated visits of the experiment's main ice floes (three visits each to floes North, Middle, and South and a 24-h process station). The sampling was started and stopped on board pre-deployment and post-recovery. During the deployments, beam 3 of the instrument was marked and aligned this with ship's bow direction, to obtain cross-referencing with ship's navigation data during post-processing. These ocean current measurements were recorded to complement simultaneous ocean microstructure profiles by a microstructure profiler (MSS), see https://doi.org/10.1594/PANGAEA.956086 for the respective raw data. Except for the second deployment (Floe South, Visit 1), the instrument recorded in beam coordinates with 1-second pings in the broadband mode (high resolution), and recorded all profiles with 2-m vertical bins. During the Floe South, Visit 1 deployment, the measurements were processed on-board the instrument in Earth coordinates as 1-min averages. The provided files include the instrument raw binary files, as well as text files containing the beam matrix and setup files. The processed and quality-controlled data are available from https://doi.pangaea.de/10.1594/PANGAEA.978165 . |
