| Summary: | Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2020T78 (a.k.a. PRIC_10_06, IRIDIUM number 300234068529570) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the 5th leg of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) in August 2020. The buoy was deployed at the CO3 of MOSAiC. The thermistor chain was 5 m long and included 241 sensors with a regular spacing of 2cm. The 40th sensor from the top was set at 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 24 August 2020 and 26 February 2021 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. The near-surface air temperature was measured at 1 m over the ice surface. In addition to temperature, geographic position, barometric pressure, tilt and compass were measured. |
