Title: A model based study of ice and freshwater transport variability along both sides of Greenland
Presenter: Camille Lique, Laboratoire de Physique des Oceans, IFREMER, Brest, France

Abstract:
A realistic simulation from 1958 to 2001 run with a global ocean/sea-ice model is used to investigate some aspects of the variability of the Arctic freshwater content, trying to understand which component of the balance is responsible for this variability. We also examine the freshwater exports to the North Atlantic and we find that their variability is controlled differently on both sides of Greenland: whilst freshwater transport variations across Davis Strait are completely determined by the variations of the total volume flux, the salinity variations due to the ice ocean flux north of Greenland are responsible for a significant part of the freshwater export variability through Fram Strait. We then focus on the very recent period, using a simulation run with a fully assimilated model to explore the possible consequences of the 2007 sea ice extent minimum on the Arctic Ocean freshwater content.
