INterContinental Atmospheric Transport of anthropogenic Pollutants to the Arctic (INCATPA)
Air monitoring of POPs and Hg has taken place at Alert, Nunavut, Canada and Ny Ålesund, Norway since the 1990s under the Northern Contaminants Program (NCP) of Canada and the Arctic Monitoring and Assessment Programme (AMAP), respectively. Through the International Polar Year (IPY) INCATPA project,...
