The structure and carbon flow of community in the pack ice, the contribution of ice community to the vertical carbon flux in the pack ice zone, and the adaptation of ice community to the micro-environments of sea ice were studied in the Canadian Basin and Greenland Sea through five Arctic cruises (the First and Second Chinese Arctic Expeditions, the 15th and 18th Germany "Polarstern" Arctic Cruises, and US-Canadian Joint "Louis St. Laurent" Canadian Basin Cruise).

本研究通过我国首次和第二次北极科学考察、参与德国第15和18北极航次和美-加2002北极航次等5个航次的调查，对北极夏、秋季浮冰的环境特性、生物群落结构和生物量、生物群落碳流、浮冰生物群落对浮冰区真光层垂向碳通量的贡献以及浮冰细菌的环境适应性进行了研究。
