Abstract
We discuss the physicochemical characteristics of aerosol over seas of the North Atlantic and Arctic Ocean measured in the 80th and two preceding (the 67th and 71st) cruises of RV “Akademik Mstislav Keldysh”. Most aerosol characteristics (concentrations of aerosol, black carbon, elemental and organic carbon, elemental composition) are shown to be larger in the atmosphere of the Baltic and North Seas as compared to the Norwegian and Barents Seas. The isotopic composition of carbon in aerosol samples was in the range of light values, indicating the predominance of carbon formed during combustion of oil products and natural gas.
