AIR-SEA EXCHANGE IN ANTARCTIC ENVIRONMENT AND SNOW MICROCOMPONENTS

The process of the air-sea exchange of matter was studied by means of laboratory experiments on Terra Nova Bay seawater with the aim of characterizing the Antarctic marine environment. Data collected in the campaigns 1988-1989, 1989-1990 are reported. The presence of surfactant and fluorescent materials is evidenced in the snow. On the basis of laboratory experiments a photochemical effect on these components is suggested for high-altitude snow depositions. Laboratory investigations on the formation of sea-water aerosol appear useful for a better understanding of natural aerosol transport.
