Temperature measurements from sea ice mass balance buoy ZS2010

CRREL-type IMB ZS2010 is an autonomous instrument that was installed on the landfast sea ice in Prydz Bay, east Antarctica in July 2010. The buoy was deployed at 69.35°S; 76.42°E, ~3 km from the coast of Station Zhongshan with initial thicknesses of snow and ice of 0.08 and 1.10 m, respectively, on 26 July 2010. Snow/Ice temperature and mass balance were measured along a chain of thermistors and via acoustic rangefinder sounders. The thermistor chain was 4.5 m long and included 45 sensors with a regular spacing of 10cm. The acoustic sensors were located above and below the ice surface, monitoring the position of the top and bottom surfaces of the ice. The resulting time series describes the evolution of temperature and snow/ice mass balance as a function of time between 26 July 2010 and 31 January 2011 in sample intervals of 2 hours. Data from several thermistors were unavailable because of a sensor failure.

CRREL型IMB ZS2010是一款自主观测浮标，于2010年7月安装在南极东部普里兹湾的固定海冰之上。该浮标布放点位为南纬69.35°、东经76.42°，距离中山站海岸约3公里；2010年7月26日布放时，初始积雪厚度与海冰厚度分别为0.08米与1.10米。本数据集通过热敏电阻阵列与声学测距仪开展雪/冰温度及质量平衡观测：热敏电阻阵列全长4.5米，包含45个传感器，采样间距固定为10厘米；声学传感器分别布设于冰面上下两侧，用于监测海冰上下表面的位置变化。所得时间序列记录了2010年7月26日至2011年1月31日期间，温度与雪冰质量平衡随时间的演化过程，采样间隔为2小时。因部分传感器发生故障，对应热敏电阻的观测数据存在缺失。
