Short summary
While the Arctic has been extensively monitored, there is still much to be learned from the Antarctic continent regarding the processes that govern the budget of atmospheric mercury species. We report here the first year-round measurements of gaseous elemental mercury (Hg(0)) in the atmosphere and in snowpack interstitial air on the East Antarctic ice sheet. The striking reactivity observed on the Antarctic plateau most likely influences the cycle of atmospheric mercury on a continental scale.
