DESCRIPTION:Title\n\nStudying the importance of Arctic gateways by using a 
 fully coupled ice-ocean model\n\n\nAbstract\n\nStudying the Arctic Ocean\,
  as an important component of the climate system\, is a challenge because 
 of the presence of sea-ice\, multiple gateways\, and interaction with the 
 Atlantic Ocean\, Pacific Ocean and ice-sheets. The fluxes of heat and fres
 hwater through the Arctic gateways have been suggested to change in the fu
 ture which can in turn affect the distribution of the Arctic sea-ice\, and
  alter the Atlantic meridional overturning circulation. Here we intend to 
 understand the relative importance of the Bering Strait and the Canadian A
 rctic Archipelago (CAA) in transporting heat and freshwater fluxes\, and t
 he corresponding regions where they affect the most. We use a regional con
 figuration of the fully coupled ice-ocean model\, NEMO (Nucleus for Europe
 an Modelling of the Ocean model) version 3.4 for a set of sensitivity expe
 riments with various gateway configurations inspired by paleogeometries of
  the Arctic. In order to reduce the degrees of freedom introduced by the p
 resence of multiple straits in the system\, we compare our model scenarios
  with the case in which both Bering and CAA are closed. We show that CAA a
 nd Bering Strait have nearly opposite impact on the Arctic Sea ice. While 
 the impact of CAA is more limited to the Arctic\, the Bering Strait affect
 s the Atlantic Ocean and plays a role in its zonal density gradient. The r
 esults will allow us to better understand the impacts caused by modulation
  of the Bering Strait and CAA fluxes\, and better founded predictions of f
 uture changes.\n
