Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA ZS2015 is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in August 2015. The buoy was deployed at 69.37°S; 76.36°E, ~100 m from the coast of Station Zhongshan with initial thicknesses of snow and ice of 0.18 and 1.16 m, respectively, on 11 August 2015. 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 of depth and time between 11 August and 6 December 2015 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. ...
