Auxiliary data from SIMBA-type sea ice mass balance buoy 2014T9

Temperature and heating-induced temperature difference profiles were measured through the atmosphere, sea ice, and ocean using a SIMBA-type sea ice mass balance buoy equipped with a several meter long thermistor chain. The present dataset was recorded by SIMBA 2014T9 (original name Awi_42) installed on drifting sea ice in the Southern Ocean during the expedition Polarstern PS82 (ANT29/9,FOS) in 2013/14. Data is available between 2014-01-17 20:00:00 and 2014-11-07 21:28:00. The thermistor chain was Variable 5 m long and included 240 sensors with a regular spacing of 2 cm. The resulting time series includes the evolution of temperature and temperature differences at 30 s and 120 s during a heating cycle of 120 s as a function of location, depth and time. The sampling intervals were usually between hourly and daily, but were most frequently configured to 6 hours for temperature, and 24 hours for temperature differences. In addition to temperatures and geographic location were measured. The present dataset was processed as follows: obvious inconsistencies (missing values) and unrealistic values of GPS position have been removed. This instrument was deployed as part of the project project Sea Ice Physics @ AWI (AWI_SeaIce).

本数据集通过搭载有数米长热敏电阻链的SIMBA型海冰质量平衡浮标（SIMBA-type sea ice mass balance buoy），在大气、海冰与海洋中测量得到温度及加热诱导温差廓线。本数据集由安装于南大洋漂流海冰上的SIMBA 2014T9（原名称Awi_42）采集所得，其部署于2013/2014年的Polarstern PS82（ANT29/9,FOS）科考航次中。数据集的有效时间范围为2014年1月17日20:00:00至2014年11月7日21:28:00。该热敏电阻链长度可变，最长可达5米，共包含240个传感器，传感器间固定间距为2厘米。所生成的时间序列包含120秒加热周期内，30秒与120秒时刻的温度及温差随位置、深度与时间的演化过程。采样间隔通常介于每小时至每日之间，其中温度数据的采样频次多设置为每6小时一次，温差数据的采样频次多设置为每24小时一次。除温度数据外，本数据集还包含地理位置观测值。本数据集已完成预处理流程：已剔除明显异常（含缺失值）以及不符合物理实际的GPS位置数据。该仪器作为AWI海冰物理研究项目（AWI_SeaIce）的一部分进行部署。
