Abstract
During the 49-th cruise of R/V Dmitry Mendeleev in August-October 1993 and PFS Polarstern cruise ARK XI/1 in July-September 1995, 22 samples of aerosols were collected in the Laptev, Kara and Barents Seas. Aerosols were studied for particle size, morphology, and composition. New results of this work are presented in this paper. The average size of particles in samples collected by meshes in different areas differ insignificantly (4.18 to 5.54 μm). In most samples mineral particles and organic matter (fibers of vegetation, pollens, diatoms) were the main components, organic carbon content was 17.6% in average. The individual anthropogenic combustion spheres with diameter from 1 to 10 μm mostly consist of: (1) Si, Al, K, and Fe in the South-Western Laptev Sea; (2) Si, Al, Fe, and K in the Central Kara Sea; (3) Fe, Ni, and Si in the Southern Kara Sea, and (4) Si, Al, Fe, and Ni in the Southern Barents Sea.
