Oranic matter in water and suspended matter of Russian Arctic rivers and seas

Primary production of the Arctic Seas based on satellite and in situ observations, carbon fluxes from the photic zone and from the land are assessed. New maps of primary production, particulate matter, total organic and inorganic carbon and their accumulation rates in bottom sediments are presented.

Biogeochemical balance of carbon and characteristic features of carbon cycle in the "atmosphere-Arctic seas-land" system are discussed.
