Hoppmann, Mario; Nicolaus, Marcel: Temperature and heating-induced temperature difference measurements from SIMBA-type sea ice mass balance buoy 2015T25 [dataset bundled publication]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.967880 (dataset in review)
Abstract:
Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2015T25 (a.k.a. Awi_74) is an autonomous instrument that was installed on drifting sea ice in the Central Arctic Ocean during the expedition Polarstern PS94 (ARK29/3, TransArcII) in 2015. 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 2015-09-12 and 2016-11-03. 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 Sea Ice Physics @ AWI (AWI_SeaIce).
