中文摘要: 目前全球节能减排任务艰巨,海冰消退后北冰洋碳汇能力增加被期待。楚科奇海及其临近海域拥有全球海洋较高的生物固碳率和深海埋存量,在整个北冰洋碳循环中举足轻重。厘清楚科奇海碳循环过程对环境快速变化的响应机制是北冰洋碳汇能力预测的基础。然而,楚科齐海碳吸收、封存对气候变化的响应尚存争议,碳循环过程的主控因子尚不明确。建立高分辨率的海洋海冰碳循环模型,可以探究海冰消退对楚科奇海海气界面CO_2吸收通量和垂直碳沉降通量的影响,认识入流与陆坡涌升增加对楚科奇海CO_2源/汇格局的作用,探讨碳的深海输运埋藏对环境变化的响应,评估楚科奇海陆架泵效率及其在全球碳汇中的作用。基于气候环境快速变化下楚科奇海域碳循环研究所面临的挑战,提出了构建北冰洋碳循环模型的基本思路及拟解决的关键科学问题。
英文摘要: Challenged by the enormous pressure to reduce the global carbon emission,it is expected that the Arctic Ocean could absorb additional atmospheric CO_2 with the retreating of sea-ice. The Chukchi Sea and adjacent waters,characterized by the highest carbon fixation in the global ocean and large carbon flux into the deep-ocean for sequestration,make substantial contributions to carbon cycling in the entire Arctic Ocean. Understanding the response mechanism of carbon cycling in this region to the rapidly changing environment is the foundation for the prediction of carbon sink in the Arctic Ocean. However,the response of carbon absorption and storage to climate change is still controversial,and the main controlling factors of the carbon cycle process remain unclear.Thus,to establish high-resolution coupled ocean-ice-carbon models can explore the influence of sea ice retreat on atmospheric CO_2 and the vertical sinking carbon fluxes in Chukchi Sea,estimate the effectiveness of growing inflow and slope upwelling on carbon sink /source patterns,discuss the response of deep-ocean carbon sequestration to the changing environment,and evaluate the effectiveness of continental shelf pump in the Chukchi Sea as well as its role in the global carbon sink. Based on the challenge for the research of the Chukchi Sea carbon cycle research with rapidly changing climate,the basic ideas of establishing Arctic Ocean carbon cycling model as well as its key scientific issues to be resolved were proposed.
