| Summary: | Temperatures were measured along a chain of thermistors. SIMBA 2020T85 (a.k.a. PRIC_09_06, IRIDIUM number 300234068704730) 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 September 2020. The buoy was deployed over a ridge at the CO3 of MOSAiC. The thermistor chain was 5 m long and included 241 sensors with a regular spacing of 2cm. The 14th sensor from the top was set at the ice surface. The resulting time series describes the evolution of temperature as a function of depth and time between 19 September 2020 and 27 June 2021 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. The temperature differences after two heating cycles of 30 and 120 s are unavailable. 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. |
