Temperature and heating induced temperature difference measurements from the sea ice mass balance SIMBA 2019T59

Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2019T59 (a.k.a. FMI05-10) is an autonomous instrument that was installed on drifting sea ice in the Central Arctic Ocean during the expedition Polarstern PS122 (MOSAiC) in 2019/20. The thermistor chain was 5 m long and included 241 sensors with a regular spacing of 2 cm. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of location, depth and time between 2019-10-07 07:30:00 and 2020-08-13 19:00:00. Sample intervals are commonly between 1 and 24 hours, but most frequently hit intervals of 6 hours for temperature and 24 hours for temperature differences. In addition to temperature and geographic position, barometric pressure, air temperature measured approximately 1m over the ice level, tilt and compass were measured. […]

沿一串热敏电阻链，对温度及其由加热引起的温差进行了测量。SIMBA 2019T59（亦称FMI05-10）是一台自主仪器，于2019/20年极地探险“极地之星”PS122（MOSAiC）期间安装在中央北极海域的漂移海冰上。该热敏电阻链全长5米，包含241个传感器，间距均匀，每2厘米一个。所得的时间序列描述了温度及其温差在两个加热周期（30秒和120秒）之后随位置、深度和时间的变化，时间范围为2019年10月7日07:30:00至2020年8月13日19:00:00。样本间隔通常在1至24小时之间，但最频繁的间隔为温度测量6小时，温差测量24小时。除了温度和地理位置外，还测量了气压、约在冰面1米处的空气温度、倾斜度和指南针方向。
