Temperature after the cooling cycle from the sea ice mass balance buoy DTC56 during MOSAiC 2019/2020

Temperature and heating-induced temperature were measured along a chain of thermistors. Digital Thermistor Chain DTC56 is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the MOSAiC expedition on 05 September 2020. The thermistor chain was 2.36 m long and included sensors with a regular spacing of 2 cm. The initial ice thickness was 1.09 m, the snow thickness was 0.00 m, and the pond depth was 0.43 m. 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 05 September 2020 and 08 September 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 ponded second/multiyear ice next to the Albedo Toblerone Line and autonomous surface flux station ASFS30: doi:10.18739/A2K649V1F.沿热敏电阻链（thermistor chain）开展了温度及加热诱导温度的测量工作。数字热敏电阻链DTC56是一款自主观测仪器，于2020年9月5日随MOSAiC科考队部署在北冰洋的漂流海冰之上。该热敏电阻链全长2.36米，传感器规则间距为2厘米。初始冰厚1.09米，雪厚0.00米，融池深度0.43米。本数据集所生成的时间序列，刻画了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，该演化过程为地理位置（GPS）、深度与时间的函数，观测时段为2020年9月5日至2020年9月8日，采样间隔为6小时。数据集还包含人工估算的气-雪界面、雪-冰界面及冰-水界面的位置信息。该DTC部署于带有融池的二年/多年冰区，毗邻反照率托布勒罗内测线（Albedo Toblerone Line）与地表通量自动观测站ASFS30：doi:10.18739/A2K649V1F。
