Ocean data of the Drift Towing Ocean Profiler (DTOP) from buoy 2018, deployed during Chinese Arctic Research Expedition 2018@en

Vertical profiles of water temperature, salinity, dissolved oxygen and chlorophyll were measured by the Drift Towing Ocean Profiler (DTOP) buoy 2018, an autonomous platform, installed on drifting sea ice (ice thickness: 155cm; snow depth: 5cm; freeboard: 10cm) in the Arctic Ocean during Chinese Arctic Research Expedition 2018. The resulting time series describes the vertical profile of the ocean below the sea ice as a function of place and time between 22 August 2018 and 24 December 2018 in sample intervals of 12 hours. In addition, the DTOP measured air temperature, relative humidity and barometric pressure and GPS position at hourly intervals.2018年中国北极科考期间，拖曳式海洋剖面浮标（Drift Towing Ocean Profiler，DTOP）作为自主观测平台，被部署于北冰洋的漂流浮冰（drifting sea ice）之上，该浮冰冰厚155cm、积雪深度5cm、干舷高度10cm。此平台完成了海水温度、盐度、溶解氧及叶绿素浓度的垂直剖面测量工作。所获时间序列数据集以12小时为采样间隔，完整描述了2018年8月22日至12月24日期间，浮冰下方海洋的垂直剖面随空间位置与时间的变化规律。除此之外，该DTOP浮标还以每小时1次的采样间隔，采集了气温、相对湿度、大气压强以及GPS定位位置数据。
