Nouvelles données sur le contenu en metaux traces des neiges de l'Antarctique, du Groenland et de l'Ile de Devon
In this paper, we present new detailed data on the trace metal content of more than 200 shallow polar snow samples collected at various depths in numerous locations mainly in Antarctica and Greenland. The samples were collected in ultraclean plexiglass or teflon tubes from the walls of hand dug pits...
