英文摘要	文石饱和度(Ω文石)是评估海洋酸化及对海洋钙质生物影响的重要指标之一。海洋吸收CO2引起海洋酸化,导致Ω文石显著下降。模式研究预测表明北冰洋表层海水将成为最先出现Ω文石<1的世界大洋。通过对北冰洋Ω文石有关研究进行归纳总结,重点阐述了北冰洋Ω文石的分布特征,讨论海—气CO2交换过程、融冰过程以及生物过程等因素对北冰洋Ω文石分布的影响,展望未来的变化趋势并提出一些关键的科学问题。; Aragonite saturation state( Ωarg) is a key parameter to assess the calcifying marine organisms' impacts of ocean acidification.Oceans are becoming more acidic and lend to the decrease of the aragonite saturation state.The Arctic Ocean is an important part of the global ocean system with a unique larger continental shelve and rupit sea ice declineing.Model simulations have presented the Arctic Ocean is expected to become the first undersaturated( Ωarg< 1) in deep oceans.However,there are still no enough adequate data to be gained due to geological politics and harsh environments.This paper attempts to summarize some conclusion and implications of the research,focused the spatial and temporal distributions of Ωargand to discuss their driving factors,including sea-air CO2exchange,sea ice melt,biological processes etc.The tendency of Ωargin the context of Arctic Ocean acidification and sea-ice retreat are also touched upon.; 南北极环境综合考察与评估专项项目(编号:CHINARE2012-2015:01-04-02;01-02-01;03-04-02;04-04;04-03-05); 国家自然科学基金重点项目“南大洋N2O源汇格局:驱动机制及其对海洋N2O收支的影响”(编号:41230529)资助
