中国第11次北极科学考察(2020年)冰基海洋水文要素剖面数据

由于北极冬季严酷的自然环境限制，人们对于冰下海洋水文环境特征、物理过程、变化规律以及冰海相互作用过程知之甚少。冰基拖曳式海洋剖面浮标采用类ARGO浮标设计，以海冰作为载体，对冰下上层海洋环境要素进行实时连续观测，获取实时观测数据，尤其对于理解海冰冻结期间冰下上层海洋的变化过程具有重要的研究意义和价值。
本数据为中国第11次北极科学考察（2020年）期间布放的冰基浮标所采集的冰下上层海洋温盐压要素。

Due to the harsh natural environment of the Arctic winter, human knowledge of the hydrological characteristics, physical processes, variation patterns, and sea ice-ocean interaction processes beneath sea ice remains very limited. The ice-based towed ocean profiling buoy adopts an ARGO-like design, taking sea ice as a carrier to conduct real-time continuous observations of environmental variables in the upper ocean beneath the sea ice and acquire real-time observational data. This is of great research significance and value, particularly for understanding the variation processes of the upper ocean beneath sea ice during sea ice freezing periods.

This dataset contains temperature, salinity and pressure data of the upper ocean beneath the sea ice, collected by ice-based buoys deployed during China's 11th Arctic Scientific Expedition in 2020.

1. Measuring Instruments
- Instrument Name: Ice-based Towed Ocean Profiling Buoy
- Instrument Model: DTOP202101
- Calibration Method: Original factory calibration of the sensors

2. Observation Method and Acquired Data
Temperature, salinity and pressure data of the upper ocean beneath the sea ice were collected via unattended autonomous observation.

3. Observation Areas
Areas including the Canada Basin and Alpha Ridge of the Arctic Ocean.
