Temperature difference after the heating cycle from the sea ice mass balance buoy DTC08 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC08 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 2.56 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 5 February 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.

研究人员沿热敏电阻链测量了环境温度与加热诱导温度。数字热敏电阻链DTC08（Digital Thermistor Chain DTC08）为自主式观测仪器，于2020年1月28日随MOSAiC科考航次部署于北冰洋漂流海冰之上。该热敏电阻链全长2.56米，传感器以2厘米的固定间距排布。所得时间序列以地理位置（GPS）、深度及时间为自变量，记录了2020年2月5日至2020年7月1日期间，单次20秒加热周期内及后续40秒内的温度演化过程，采样间隔为6小时。数据集同时包含人工估算的气-雪、雪-冰及冰-水界面位置。该热敏电阻链部署于福特里奇（Fort Ridge）附近的平坦一年冰区。冰质量平衡仪SIMBA 2020T60部署于福特里奇，DOI：10.1594/PANGAEA.924269。辐射观测站2020R10部署于福特里奇附近的平坦一年冰区，DOI：10.1594/PANGAEA.949124。
