Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy DS2018a: 30 s after the heating cycle

Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA DS2018a is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2018. The buoy was deployed at 68.57°S; 77.95°E, ~1 km northwest off Australian Station Davis Coast with initial thicknesses of snow and ice of 0.06 and 0.80 m, respectively, on 28 May 2018. 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 28 May and 10 November 2018 in sample intervals of 6 hours for temperature and 24 hours for temperature differences.

本数据集记录了沿热敏电阻链（thermistor chain）测得的温度与加热诱导温差。SIMBA DS2018a是一套自主观测仪器，于2018年5月部署在南极东部普里兹湾（Prydz Bay）的固定冰（landfast ice）上。该浮标于2018年5月28日部署在南纬68.57°、东经77.95°处，距离澳大利亚戴维斯海岸（Davis Coast）西北约1公里，当时积雪与冰层的初始厚度分别为0.06米与0.80米。此次使用的热敏电阻链总长5米，包含240个传感器，传感器间距固定为2厘米。所得时间序列记录了2018年5月28日至11月10日期间，两次时长分别为30秒和120秒的加热循环完成后，温度与温差随深度和时间的演化情况；其中温度采样间隔为6小时，温差采样间隔为24小时。
