Local and Regional Scale Impacts of Arctic Shipping Emissions Off the Coast of Northern Norway
International audience Decreased sea ice extent due to warming has already resulted in the use of new shipping routes through the Arctic. Marine traffic is a source of air pollutants, including NOx, SO2, and aerosols, and is predicted to be an increasingly significant source of Arctic pollution in t...

International audience Decreased sea ice extent due to warming has already resulted in the use of new shipping routes through the Arctic. Marine traffic is a source of air pollutants, including NOx, SO2, and aerosols, and is predicted to be an increasingly significant source of Arctic pollution in the future. Currently there are large uncertainties in both global and Arctic shipping emissions, leading to uncertainties in diagnosing current and future impacts of marine traffic on Arctic air quality and climate.This study focuses on the local scale, examining chemical/aerosol transformations occurring in individual ship plumes. Measurements of ship pollution in the Arctic taken during the EU ACCESS aircraft campaign (Arctic Climate Change, Economy and Society) in July 2012 are used to quantify the amount of pollution emitted from different ship types.
