中国第13次南极科学考察(1996-1997)纳拉湾冰水界面温度数据

冰水界面温度数据于1996年3月至11月采自中山站近岸海冰区内拉湾中心点，水深147.5米。使用15组热敏电阻传感器，每组间隔15厘米，自冰表到冰水界面长期布设而获得。目的是获得精确的冰柱和冰水界面的温度分布和变化。结果显示：冰水界面—冰柱底部—冰下水柱上层存在明显的温度季节变化，其中冰下水柱上层与海冰底部的最大温差可达0.3℃，表明冰水界面局部存在一定的对流混合过程。

Water-ice interface temperature data were collected between March and November 1996 at the central point of the inner La Bay within the nearshore sea ice region adjacent to Zhongshan Station, at a water depth of 147.5 meters. The data were acquired through long-term deployment of 15 thermistor sensor sets, with each set spaced 15 cm apart, spanning from the ice surface down to the water-ice interface. The primary objective of this monitoring campaign was to obtain accurate temperature distributions and temporal variations within the ice column and at the water-ice interface. Findings indicate that significant seasonal temperature variations occur at the water-ice interface, the base of the ice column, and the upper layer of the sub-ice water column. The maximum temperature difference between the upper sub-ice water column and the sea ice base reaches up to 0.3°C, indicating that localized convective mixing processes take place at the water-ice interface.
