Abstract: The Canadian Arctic Archipelago (CAA) is one of the main pathways for freshwater exiting the Arctic Ocean. The amount of exported freshwater influences the deep water formation in the North Atlantic, which is crucial for the meridional overturning circulation (MOC).

Modelling ocean and sea ice conditions of the CAA is difficult because of narrow straits and complex coastlines. The assessment of a high resolution model study for the period 1958-2007 is presented, which applies the Finite Element Sea-ice Ocean Model (FESOM) in a global configuration. The unstuctured mesh approach allows for local refinement in areas of interest (around 5 km mesh resolution in the CAA) and accurate representation of coastlines.

Volume and freshwater transports through the CAA show a strong interannual variability. Mechanisms driving the flow through the archipelago are investigated by exploring the sea surface height difference between Baffin Bay and the Arctic Ocean, far field wind fields and large scale pressure patterns like the North Atlantic Oscillation.

Experiments with different mesh resolutions in the CAA are conducted and their effects on freshwater transports through the CAA are presented.

Understanding variations of volume and freshwater fluxes through the Canadian Arctic Archipelago to project future changes

Abstract: Most climate models do not resolve transports through the Canadian Arctic Archipelago (CAA) - although these transports are believed to be important to deep convection in the Labrador Sea. An understanding of the statistical relationship between transports and large-scale forcing can be used, with climate model outputs, to project future changes to the transports. Here we use a 6km resolution ocean and sea ice model to investigate the variability, control and forcing mechanisms of the fluxes through the CAA. Our analysis confirms the previously proposed control of volume fluxes by variations of sea surface height in "upstream" regions (the Beaufort Sea) and "downstream" regions (Baffin Bay), and possible linkages with wind stress in these regions. The effectiveness of these control and forcing mechanisms is shown to vary for fluxes through different sections and for different seasons.
