Summary: | Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2019T47 (a.k.a. FMI_04_06, IRIDIUM number 300234064817930) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the 1st leg of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) in October 2019. The buoy was deployed at a P site with initial thicknesses of snow and ice of 0.10 and 0.34 m, respectively, on 13 October 2019. The thermistor chain was 5 m long and included 240 sensors with a regular spacing of 2 cm. The depths for the sensors are 78 to -400 cm, referring to the initial interface between snow and ice. 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 depth and time between 13 October 2019 and 8 February 2020 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. In addition to temperature, geographic position were measured. |
