Temperature after the cooling cycle from the sea ice mass balance buoy DTC23 during MOSAiC 2019/2020

DOI

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC23 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 10 December 2019. The thermistor chain was 4.16 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 10 December 2019 and 25 March 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 the deformed second-year ice next to RV Polarstern, remote sensing site RS2 and X-band scatterometer.

Temperature after the cooling cycle and temperature before the heating cycle both represent in situ temperature. The temperature before the heating cycle may contain errors in measurements and is provided for reference. It is recommended to use temperature after the cooling cycle and temperature difference after the heating cycle for further analysis.
