Arctic Ships

PI: Claire Granier
Institution: CIRES and NOAA/CSD
Abstract:
Study of pollution from future ship traffic in the Arctic Northern Passages. A first study was published in GRL (vol 33, L13807, doi:10.1029/2006GL026180, 2006) looking at the impact of ships emissions on the levels of ozone and ozone precursors due to the opening of new shipping routes in the Arctic passages in the decades ahead. In the planned study, we would like to compare the sea ice area and the sea ice thickness provided by different IPCC models in order to evaluate the likeliness of shipping in the Arctic area. From these comparisons, we will design shipping routes in the Arctic and develop emissions distributions from ships in the Arctic area. Using these data, we will be able to asses the pollution expected from a fleet of ships in the Arctic. We will use the distribution of ice provided by the different IPCC models to evaluate the uncertainty of our calculations.
