Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy 2017T45: 30 s after the start of the heating cycle

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 2017T45 (original name Akva_01) installed on landfast sea ice at Svalbard,Arctic during the expedition Svalbard FAABulous in 2017. Data is available between 2017-03-09 19:00:00 and 2017-05-03 14:09:00. 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 FAABulous.

本数据集依托搭载有数米长热敏电阻链的SIMBA型海冰质量平衡浮标，完成了大气、海冰及海洋中温度与加热诱导的温差剖面的测量工作。本次数据集由2017年北极斯瓦尔巴群岛FAABulous科考航次中，部署于斯瓦尔巴群岛固定海冰上的SIMBA 2017T45（原名称为Akva_01）采集获取。数据有效覆盖时段为2017年3月9日19:00:00至2017年5月3日14:09:00。该热敏电阻链为可变长度设计，总长可达5米，共包含240个间距为2厘米的传感器。所生成的时间序列涵盖了120秒加热周期内，30秒与120秒时刻的温度及温差随位置、深度与时间的演化规律。采样间隔通常介于每小时至每日区间内，其中温度数据的采样频次多设置为6小时一次，温差数据则多采用24小时的采样间隔。除温度参数外，数据集同步采集了地理位置信息。本次数据集已完成标准化预处理：已剔除明显异常值（含缺失值）及GPS位置不合理的数据。该设备作为FAABulous项目的组成部分完成部署。
