On the resonance and influence of the tides in Ungava Bay and Hudson Strait

Abstract

The tides of Leaf Basin in Ungava Bay may be the world's highest. An analysis of the frequency dependence of the response to outside forcing, a normal mode analysis, and a study of the damped oscillation of an initial disturbance, suggest that the Ungava Bay/Hudson Strait region has a natural period of about 12.7 hours and so is close to resonance with the tidal forcing. The implications for regional and global tides in the present, past, and future are explored. Copyright 2007 by the American Geophysical Union.
