Effects of Global Warming on Carbon Cycling in Arctic Soils

北极土壤广袤，富含有机物质，是陆地生物圈的碳汇。总的项目目标是评估北极土壤中有机成分的数量和质量，预测其释放速率的增加，并评估由于全球变暖加速而导致的永久冻土融化时其分解和移动的潜力。

Arctic soils are extensive and have an abundance of organic matter acting as a carbon sink in the terrestrial biosphere. The overall project objectives are to assess the quantity and quality of the organic constituents in arctic soils, to predict their increased rates of release, and to evaluate their potential for decomposition and movement upon thawing of permafrost due to accelerated global warming.
