Polar northern and southern regions are at forefront of changes in climate forcing and climate-biogeochemical-ecological interactions. It is critical that we understand the rate and magnitude of the changes in ocean-atmosphere-cloud-climate interactions likely to occur, and their impact on local and global ecosystems. POLAR-CHANGE (Aerosol emissions from POLAR CHANGing Environments) aims to study the sources, composition and dynamics of aerosols in Arctic and Antarctic environments. After briefly presenting the background of the project, this talk will focus on the POLAR CHANGE cruise. An international team of researchers travelled around Antarctica in February-March 2023 in order to study in depth the role of marine aerosols in the regulation of the Earth's climate. 23 researchers of 14 different nationalities from 5 continents took part in the expedition on board of the oceanographic vessel Hespérides. I will focus on the interdisciplinary ocean-atmosphere aspects of the cruise, including some hints about dealing with Antarctiness Peer reviewed
