Abstract:

The results of studies of atmospheric aerosol in the 95th and 96th cruises of RV Akademik Mstislav Keldysh in the waters of the Barents and Kara Seas are presented. It is shown that the average values of aerosol characteristics over the Barents Sea are 1.1–1.9 times greater than over the Kara Sea. Taking into account the new data, the long-term average values of aerosol characteristics over these seas have been clarified: the volume concentrations of submicron aerosol were 0.47 and 0.44 mm³/cm³, respectively; concentrations of coarse aerosol were 2.17 and 1.65 mm³/cm³; mass concentrations of the absorbing substance (black carbon) were 67 and 36 ng/m³; aerosol optical depths of the atmosphere (0.5 microns) were 0.078 and 0.038.

Keywords:

arctic seas, aerosol, black carbon, ion composition, aerosol optical depth
