Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy 2012T29: 120 s after the heating cycle

DOI

Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2012T29 (a.k.a. ronnie_04) is an autonomous instrument that was installed on drifting sea ice in the Central Arctic Ocean during the expedition Polarstern PS80 (ARK27/3, IceArc) in 2012. The thermistor chain was 5 m long and included 240 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 2012-09-04 and 2013-10-04. 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. The data set has been processed as follows: obvious inconsistencies (missing values) and unrealistic values in position have been removed. This instrument was deployed as part of the project MPI-HB.
