The 2004-2007 scientific research program CHIMERPOL II consists in improving the results obtained during the CHIMERPOL I programme around three main ideas: 1-Understand physico-chemical processes of oxidation of elemental gaseous mercury in the atmosphere during Mercury Depletion Events (MDE) in Corbel, Svalbard from 2004 to 2007 with a continuous monitoring station for gaseous mercury and its speciation, 2-Evaluate deposition and emission fluxes of mercury above the Arctic snow pack by a continuous monitoring of these fluxes in Corbel, Svalbard and in Station Nord, Greenland, from 2005 to 2007. 3-Determine the Air-Snow-Firn-Ice transfer function for mercury and its speciation with a complete balance of mercury in the different compartments in Summit, Greenland from 2006 to 2007.
Snow samples and filters are stored in the Laboratoire de Glaciologie et Géophysique de l'Environnement at -25°C.
