Abstract:

The results of mass soot concentration measurements in the near-water layer of the atmosphere during 2 cruises of the "Academic Fedorov" research vessel (from September 25 to October 23, 1998 on the route Saint-Petersburg - Franz-Joseph Land and from November 8, 1999 to April 30, 2000 on route Saint-Petersburg - Antarctica - South Ocean), the 27-th cruise of the "Academician Ioffe" research vessel (from April 6 to May 19, 2009 from Ushuaia (Tierra del Fuego) to Gdansk (Poland)) and at the Russian Antarctic station Bellingshausen (from December 20, 2001 to March 11, 2002). It is shown that the soot content in the atmosphere over Arctic Ocean in October 1998 is comparable to that, obtained at stationary stations in 1989-1992. The latitudinal dependence (soot content decrease with latitude increase) is observed in the Southern Hemisphere. The average concentration of soot at Belling-shausen station and, in South Ocean comes to 19-28 ng/m3 and is comparable with the level of pollution at foreign stations McMurdo and Ferraz.
