Plankton-derived emissions of trace gases and aerosols in the Southern Ocean - Highlights of the PEGASO 2015 cruise to Antarctica
2 pages, figures The oceans are strong and pervasive sources of tiny airborne particles (called aerosols) with important implications for the regulation of atmospheric chemistry, optics, cloudiness and, therefore, climate. The PEGASO project aims to investigate the plankton-derived production of aer...
