Temperature after the cooling cycle from the sea ice mass balance buoy DTC10 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC10 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 28 January 2020. 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 28 January 2020 and 1 July 2020 in sample intervals of 6 hours. It also contains manually estimated position of air-snow, snow-ice, and ice-water interfaces. The DTCs was installed in level first-year ice next to the Fort Ridge. Ice mass balance SIMBA 2020T60 was installed at the Fort Ridge: doi:10.1594/PANGAEA.924269. Radiation station 2020R10 was installed in level first-year ice next to the Fort Ridge: doi:10.1594/PANGAEA.949124.

本数据集沿热敏电阻链（thermistor chain）采集了环境温度与加热诱导温度数据。数字热敏电阻链DTC10（Digital Thermistor Chain DTC10）为一款自主式观测仪器，于2020年1月28日随MOSAiC科考队（MOSAiC expedition）部署于北冰洋的漂流海冰之上。该热敏电阻链总长4.16米，传感器布设间距固定为2厘米。所得时间序列以2020年1月28日至2020年7月1日为观测时段，采样间隔为6小时，记录了20秒加热周期内及加热结束后后续40秒内的温度演变过程，数据维度涵盖地理位置（GPS）、传感器深度与观测时间。数据集同时包含人工估算得到的气-雪、雪-冰及冰-水界面位置。该数字热敏电阻链部署于福特岭（Fort Ridge）旁的平坦一年冰（first-year ice）区域。冰质量平衡观测仪SIMBA 2020T60（Ice mass balance SIMBA 2020T60）部署于福特岭，对应数据集DOI为：10.1594/PANGAEA.924269。辐射观测站2020R10（Radiation station 2020R10）部署于福特岭旁的平坦一年冰区域，对应数据集DOI为：10.1594/PANGAEA.949124。
