Namibia is characterised by some of the most extreme climate regimes ranging from the cold Benguela Current to the hyper-arid coastal deserts of the Namib region. Fog and low-clouds are typical features, affecting the coast and inland up to about 60-100 km, where they have a higher contribution to the total water volume than rainfall, […]

A l’été 2022, PEGASUS a participé à la campagne de mesure du projet ACROSS (Atmospheric Chemistry of the Suburban Forest) pour étudier les interactions entre les composés chimiques relâchés par les activités urbaines de Paris et les forêts environnantes. PEGASUS était basé sur le super-site dans la forêt de Rambouillet, contribué par le LISA et […]

PEGASUS et ses personnels se préparent à participer à la campagne d’observation du projet TONGA. Il s’agit d’une croisière de 37-jour dans le Pacifique sud-ouest tropical qui aura lieu à bord du R/V L’Atalante en décembre 2019. Le projet TONGA étudie le rôle des micronutriments d’origine hydrothermale sur la productivité océanique et l’export de carbone.
