Temperature after the cooling cycle from the sea ice mass balance buoy DTC33 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC33 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 22 November 2020. The thermistor chain was 5.12 m long and inc...

Description
Summary:Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC33 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 22 November 2020. The thermistor chain was 5.12 m long and included sensors with a regular spacing of 2 cm. The resulting time series describes the evolution of temperature during the heating cycle of 20 s and after the heating cycle during the following 40 s as a function of geographic position (GPS), depth, and time between 22 November 2019 and 15 July 2020 in sample intervals of 6 hours. It also contains manually estimated positions of air-snow, snow-ice, and ice-water interfaces. The DTC was installed in undeformed second-year ice at Transect North: https://doi.org/10.1525/elementa.2022.00048. Radiation station 2020R14 was installed next to the DTC33: doi:10.1594/PANGAEA.948572.
