Paper Abstract

Data of measurements in Russian Antarctic expeditions (51st-62nd RAE) are used to analyze the specific features of the spatial distribution of the atmospheric aerosol optical depth, concentrations of aerosol and absorbing substance (black carbon) in the southern part of the World Ocean. We found no statistically significant differences in the average aerosol characteristics between three sectors of the Southern Ocean. Near Antarctic islands, we revealed the specific features in the spatial variations of aerosol characteristics: when the separation distance from islands increases to 250 km, the particle concentrations become two times larger, and black carbon concentrations become 26% smaller, primarily because of the redistribution between contributions of island (local) and maritime sources of aerosol, differing by the concentrations of aerosol and content of absorbing substance in it.
