中国第35次南极科学考察（2018-2019年）中山站海冰厚度观测数据

海冰观测是中山站业务化观测的重要组成部分，通过对中山站附近海域海冰相关参数的多年持续观测，一方面可以实时监测海冰变化，为科学考察船冰区航行和海冰卸货等提供保障；另一方面可以揭示南极海冰的物理特征，改进海冰模式物理参数化方案，推动南极海冰以及全球气候变化研究。本数据为中国第35次南极科学考察中山站海冰厚度数据，采用人工定点钻孔观测与EM31走航断面观测相结合的方式观测。数据内容包含时间、经度、纬度、冰厚、雪厚、盐度、表层海水温度等。

Sea ice observation is a critical component of the operational monitoring program at China's Zhongshan Station. Through years of continuous observations of sea ice-related parameters in the sea areas adjacent to Zhongshan Station, on one hand, real-time monitoring of sea ice changes can be achieved, providing support for ice-region navigation of scientific research vessels and sea ice unloading operations; on the other hand, it can help reveal the physical characteristics of Antarctic sea ice, improve the physical parameterization schemes of sea ice models, and advance research on Antarctic sea ice and global climate change. This dataset comprises sea ice thickness data collected at Zhongshan Station during China's 35th Antarctic Scientific Expedition, which was acquired via a combined approach of manual fixed-point drilling observations and EM31 underway transect observations. The dataset includes time, longitude, latitude, ice thickness, snow thickness, salinity, surface seawater temperature, and other relevant parameters.
