CHEMICAL COMPONENTS OF MARINE AEROSOL OVER THE ANTARCTIC SEA
Fifty-eight samples were collected over the Antarctic Sea between December 3 and 31 in 1987. The sampling was carried out on board the research vessel "SHIRASE" by a medium volume sampler, which can be automatically operated every 12h at the sampling rate of 150l/min. The samples were anal...

It is considered that Cl loss is due to the reaction of sea salt aerosol with sulfate aerosol even over the Antarctic Sea.
