Description
Summary:Development and some highlights from four years "Mercury Depletion Event (MDE) Campaigns" at Ny-Aesund, Svalbard (78o54'N, 11o53'E) where research groups from all together eight countries have participated are presented. The purpose of this effort was to provide further quantitative information on mercury in different environmental compartments including air, snow, ice cores and seawater during polar spring and extend the database of MDEs. To contribute to the knowledge, we have conducted time-resolved speciated determination of mercury in the atmosphere (GEM, RGM, PM) and snow (total mercury) at two altitudes (474 and 12 m a.s.l.). At the sea level gastransfer experiments over snow and sea surfaces have been conducted. The observations have been analysed using meteorological and remote-sensing data.
