2017年12月10日，中国科考船R/N雪龙号在中国第五个南极科考站建设地点南极洲不可表达岛(南极洲)附近遭遇大片陆冰。利用多源卫星云图和气象资料，分析了该事件季的冰情，重建了陆冰的发育过程。9月底和10月初的两个阶段被确定为造成最终冰层范围的因素。这两次事件与局地和大范围的天气条件高度相关。2003年至2017年的卫星图像显示，15年中有4年经历了严重的陆上结冰条件，这表明这并不是一个罕见的现象。
On 10 December 2017, a Chinese research vessel R/N Xuelong encountered an extensive area of landfast ice offshore Inexpressible Island (Antarctica) near the location where the fifth Chinese Antarctic research station is to be built. Using multi-source satellite images and weather data, we analyzed the ice conditions during the event season and reconstructed the development of landfast ice. Two stages in late September and early October were identified as contributing to the final ice extent. These two events are highly related to local- and large-scale weather conditions. Satellite images from 2003 to 2017 showed that four in fifteen years experienced severe landfast ice conditions, suggesting that it is not a rare phenomenon.
