The mooring Taymyr-T1-13 was anchored at a water depth of 59 meters on the seasonally ice-covered shelf of the north-western Laptev Sea. The site is dominated by the on-shelf transport of water from the shelf break. The mooring was equipped with RDI-Workhorse ADCPs for current measurements. The current was recorded at intervals of 1 m (300 kHz ADCP) and 0.5 m depth (1200 kHz ADCP). The measurement interval was 1 hour. The ADCP current measurements were corrected for declination. The declination was calculated using the Enhanced Magnetic Model (EMM2017 on NOAA.gov.). The mooring was deployed in September 2013 during the Transdrift 21 expedition and retrieved in September 2014 during the Transdrift 22 expedition on board the Viktor Buinitsky. The expeditions were carried out as part of the German-Russian partnership Laptev Sea System and the BMBF-funded Transdrift project.
