Current and echo backscatter measurements on the Laptev Sea shelf in 2013-2014 at mooring site Kotelny-T1-13

The mooring Kotelny-T1-13 was deployed in September 2013 at a water depth of ~67 m on the seasonally ice-covered shelf of the northeastern Laptev Sea (Siberian Arctic) and recovered in September 2014. The location of the mooring is characterized by the transport of water masses from the shallow shel...

Description
Summary:The mooring Kotelny-T1-13 was deployed in September 2013 at a water depth of ~67 m on the seasonally ice-covered shelf of the northeastern Laptev Sea (Siberian Arctic) and recovered in September 2014. The location of the mooring is characterized by the transport of water masses from the shallow shelf of the Laptev Sea to the Amundsen Basin. The 47 m long mooring was equipped with RDI-Workhorse ADCPs for current measurements and Seabird SBE37 CTDs for temperature and salinity measurements (doi.org/10.1594/PANGAEA.924055). 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.). A total of four moorings (1893, Taymyr, Kotelny, Vilkitsky) were deployed on the shelf of the Laptev Sea in September 2013 during the Transdrift 21 expedition and recovered in September 2014 during Transdrift 22 on board the research vessel Viktor Buinitsky (doi.org/10.1594/PANGAEA.908837). The expeditions were carried out as part of the German-Russian partnership Laptev Sea Systems and the BMBF-funded Transdrift project.
