The present dataset was recorded by SIMBA 2018T49 (original name FMI_0408) installed on drifting sea ice in the Southern Ocean during the expedition Polarstern PS111 (ANT33/2,FROST) in 2018. Data is available between 2018-02-16 15:20:00 and 2018-04-24 02:04:00. The thermistor chain was Variable 5 m long and included 241 sensors with a regular spacing of 2 cm. The resulting time series includes the evolution of temperature and temperature differences at 30 s and 120 s during a heating cycle of 120 s as a function of location, depth and time. The sampling intervals were usually between hourly and daily, but were most frequently configured to 6 hours for temperature, and 24 hours for temperature differences. In addition to temperatures and geographic location were measured. The present dataset was processed as follows: obvious inconsistencies (missing values) and unrealistic values of GPS position have been removed. This instrument was deployed as part of the project project FMI.
