Short summary

This paper presents a multi-year record of atmospheric gaseous elemental mercury (Hg(0)) at Dumont d’Urville (DDU) on the East Antarctic coast. This record reveals particularities that are not seen at other coastal Antarctic sites, likely due to the more frequent arrival of inland air masses at DDU than at other coastal sites, and to the influence of oceanic air masses. This study confirms the influence of processes observed inland on the cycle of atmospheric mercury at a continental scale.
