- The project
This project aims to study ocean-atmosphere interactions with a focus on studying the connections between ocean primary production and gas-phase and particulate compounds in the atmosphere having climate activity due to their interaction with solar radiation. To achieve the objectives of the project, for the first time, measurements and sampling carried out simultaneously in the atmosphere (dimethyl sulfide, methanesulfonic acid, sugars, amino acids and methoxyphenols) at Italian base "Mario Zucchelli" (MZS), measurements in the sea (nutrients, chlorophyll and physiological state of phytoplankton) and satellite data were carried out and correlated.
Species concentrations in the atmosphere correlated with phytoplankton activity were correlated with oceanic parameters (chlorophyll and primary productivity), this correlation was interpreted as a function of algal and phytoplankton population (taxonomic composition and physiological status), variations in total and photosynthetic radiation intensity, and to the extent and dynamics of sea ice in the Ross Sea. This area is particularly important for biogenic aerosol production due to the presence of a large area of Polynia that promotes phytoplankton development prior to the melting of the entire sea ice belt around Antarctica.
Understanding and quantifying the correlation between compounds in the atmosphere and oceanic primary productivity (with the consequent effects on 'CO2 uptake from the atmosphere) is of relevant importance in Global Change studies because this interaction is affected, but in turn influences, climate variations.
