Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA DS2014 is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2014. The buoy was deployed at 68.57°S; 77.93°E, ~1.5 km northwest of Australian Station Davis with initial thicknesses of snow and ice of 0.06 and 0.58 m, respectively, on 29 May 2014. 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 29 May and 4 November 2014 in sample intervals of 2~6 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. ...
