MARCUS - Southern Ocean Boundary Layer Aerosol in Focus

The Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) field campaign is acquiring comprehensive observations of aerosols including cloud condensation nuclei and ice nucleating particles in the Southern Ocean boundary layer.

The second ARM Mobile Facility is currently installed on the Australian Antarctic supply vessel Aurora Australis as it routinely travels between Hobart and the Antarctic. MARCUS has a strong link with the SOCRATES campaign targeting on clouds in the Southern Ocean and their connection to air-sea exchange processes.

IMK-AAF is participating in MARCUS by monitoring the biological aerosol with the WIBS4 instrument.
