Temperature after the cooling cycle from the sea ice mass balance buoy DTC32 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC32 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 deformed second-year ice at Transect North. Radiation station 2020R14 was installed next to the DTC32: doi:10.1594/PANGAEA.948572.

沿热敏电阻链开展了环境温度与加热诱导温度的测量。数字热敏电阻链（Digital Thermistor Chain，DTC32）为自主式观测仪器，于2020年11月22日随北极气候多学科漂流观测站（MOSAiC）科考航次部署于北冰洋漂流海冰之上。该热敏电阻链总长5.12 m，传感器按2 cm的固定间距均匀布设。所生成的时间序列以地理位置（GPS）、水深及时间为自变量，采样间隔为6小时，记录了2019年11月22日至2020年7月15日期间，20秒加热周期内及加热结束后后续40秒内的温度演化过程。该数据集同时包含人工估算得到的气-雪、雪-冰及冰-水界面的位置信息。该DTC部署于北向断面（Transect North）的变形二年生海冰区域。紧邻DTC32还部署了辐射观测站2020R14，其DOI标识为10.1594/PANGAEA.948572。
