Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA ZS2013b is an autonomous instrument that was installed on the landfast sea ice in Prydz Bay, East Antarctica, in May 2013. The buoy was deployed at 69.33°S; 76.44°E, ~5 km from the coast of Chinese Station Zhongshan with initial thicknesses of snow and ice of 0.10 and 0.58 m, respectively, on 24 May 2013. The thermistor chain was 5 m long and included 240 sensors with a regular spacing of 2cm. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function depth and time between 24 May and 3 October 2013 in sample 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 and unrealistic values have been removed.
