About 10 % of atmospheric carbon dioxide is sequestered in the ocean above 60°N, half of which is in coastal seas where 10 % of the global riverine freshwater volume flows in. Five of the world’s largest rivers convey in the Arctic Ocean (AO) huge quantities of dissolved carbon in the organic (DOC)...
