Spatial structure of the M 2 tidal wave in the canadian arctic archipelago

The surface M2 tide in the Canadian Arctic Archipelago (CAA) is reproduced on the basis of the QUODDY�4 threedimensional finiteelement hydrodynamic model. Particular emphasis has been placed on comparing model estimates for the amplitudes and phases of tidal elevations and the parameters of ellipses (major semiaxis and eccentricity) of the barotropic tidal current velocity with observational data. We present their spatial distributions and the distributions of averaged (over a tidal cycle) values of the density, horizontal transfer, and dissipation rate of barotropic tidal energy. It is found that the CAA is a much less effective dissi� pator of barotropic tidal energy than the World Ocean.
