Sedimentary organic carbon accumulation rate in continental margin seas is more than one order higher than that of the oceans. Ocean margins play a very important role in global carbon budget since about 80% of terrestrial and marine organic carbon buried in the continental shelves. Of the Arctic Ocean total area over 30% is shelf, and it is accounted for one-fourth of global shelf area. Because of its ice cover biological pump in the Arctic Ocean was thought to be very limited, thus it has not been considered...

Sedimentary organic carbon accumulation rate in continental margin seas is more than one order higher than that of the oceans. Ocean margins play a very important role in global carbon budget since about 80% of terrestrial and marine organic carbon buried in the continental shelves. Of the Arctic Ocean total area over 30% is shelf, and it is accounted for one-fourth of global shelf area. Because of its ice cover biological pump in the Arctic Ocean was thought to be very limited, thus it has not been considered as a sink of carbon dioxide. With the recent observation of global warming, decreasing of ice cover in shelf area would lead to potential simulate primary production, thus increase sedimentary organic carbon accumulation rate in the shelves. In this review paper, organic carbon sources, riverine discharge of sediment and nutrients, sea ice cover variation, and biological pump were discussed in order to evaluation potential increasing of sedimentary organic carbon accumulation in the arctic shelves under global warming.

陆架边缘海有机碳的堆积速率比大洋高一个数量级 ,全球大约有 80 %以上的沉积有机碳埋藏于陆架地区。北极陆架是世界上最大的陆架 ,占全球陆架面积的 1 / 4 ,然而由于相关的工作较少 ,目前对北极沉积有机碳埋藏情况及其对全球的贡献还知之甚少。北极地区沉积有机碳埋藏主要取决于生物泵 ,而生物泵过程一个主要的限制因子是海冰的覆盖。近几十年来随着全球变暖 ,北极海冰覆盖面积正在快速减小。本文从北极沉积有机碳的来源、河流携带的沉积物输入、海冰覆盖率、营养盐来源等方面初步讨论了陆源输入和生物泵过程对沉积碳来源和埋藏时空变化的影响。结合两次北极考察的初步结果指出 ,全球变暖很可能使北极陆架边缘海成为沉积有机碳的高效汇区。
