The results are presented of new cycle of investigations of the aerosol optical depth (AOD) of the atmosphere, carried out aboard of the research vessel Akademik Fedorov at the first stage of the 53d Russian Antarctic Expedition (November, 2007 – March, 2008). Statistical characteristics of spectral AOD, Angstrцm exponent and columnar water vapor of the atmosphere in some regions of Southern Hemisphere are discussed. Generalized data on latitudinal dependence of aerosol turbidity over ocean, obtained in several expeditions, are presented. The data show a linear decrease of AOD by approximately 5 times during moving from equator to Antarctica. It is noted than AOD of the atmosphere near Antarctica in the post-volcanic period (1995–2008) is characterized by stably low values (about 0.025) in the center of the visible range at a value of spatial-temporal variability (rmsd) of 0.01–0.02.
