Short summary

We detect and track mesoscale eddies in the Canadian Basin of the Arctic Ocean and describe their spatio-temporal characteristics in a high resolution pan-Arctic model. Results show eddies of typical size 12 km, lasting 10 d and travelling 11 km, with roughly an equal number of cyclones and anticyclones detected. Seasonal, decadal and interannual changes of the number of eddies detected show strong correlations with the ice cover, and with the mean circulation of the basin.
