The Autumn Distribution of the CO_2 Partial Pressure in Bottom Waters of the East Siberian Sea

摘要

Climate changes in the Arctic region result in transformation of atmospheric circulation, degradation of the ice cover, and a reduced "ice free" season, which stimulates processes in the land-sea and lithosphere-hydrosphere-atmosphere systems. It is thought that these processes influence substantially the carbon cycle in the Arctic seas. Serving as a connecting link between terrestrial, oceanic, and atmospheric carbon reservoirs, the coastal zone of shelf seas plays an important role in the carbon cycle. The main agents supplying allochtho-nous carbon to the Arctic shelf are rivers as well as a degrading coastal (and subaqueous) ice complex that contains fossil labile organic matter.
