Received: 30 September 2013 – Published in Ocean Sci. Discuss.: 05 November 2013 Abstract. The resonances of Hudson Bay, Foxe Basin and Hudson Strait are investigated
using a linear shallow water numerical model. The region is of particular
interest because it is the most important region of the world ocean for
dissipating tidal energy.

The model shows that the semi-diurnal tides of the region are dominated by
four nearby overlapping resonances. It shows that these not only affect
Ungava Bay, a region of extreme tidal range, but they also extend far into
Foxe Basin and Hudson Bay and appear to be affected by the geometry of those
regions. The results also indicate that it is the four resonances acting
together which make the region such an important area for dissipating tidal
