Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA ZS2013a is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2013. The buoy was deployed at 69.37°S; 76.36°E, ~100 m from the coast of Chinese Station Zhongshan with initial thicknesses of snow and ice of 0.02 and 0.69 m, respectively, on 15 May 2013. The thermistor chain was 4.5 m long and included 108 sensors with a regular spacing of 4cm. 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 depth and time between 15 May and 27 November 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.
