Abstract:
A total of four moorings ("1893", "Taymyr", "Kotelny", "Vilkitsky") was deployed in September 2013 during the Transdrift XXI - expedition and recovered in September 2014 during Transdrift XXII aboard the Viktor Buinitsky. The expeditions were carried out in the framework of the German-Russian "Laptev Sea Systems" partnership, and within the BMBF-funded "Transdrift"-project. The moorings were designed to collect information on the general shelf circulation, to study ice-ocean-atmosphere processes, and to understand the role of the Lena River on the oceanography of the Laptev Sea.

Comment:
The moorings were equipped with RDI-Workhorse ADCPs for current velocity and Seabird SBE37 for temperature and salinity measurements. Sampling intervals were 1 hour for ADCP, and 30 minutes for SBE37. Currents were corrected for misalignment based on angles extracted from: https://geomag.nrcan.gc.ca/calc/mdcal-en.php. Some but not all SBE37 models included a pressure sensor. If pressure was recorded, the data files provide pressure and the converted water depth. For models without a pressure sensor, the data file lists only a constant value indicating the targeted instrument depth. Current velocities were checked and quality-controlled, depth bins that were corrupted by mooring components were removed. Temperature and salinity data were despiked, and outliers exceeding three times the standard deviation were removed and interpolated.
