Accurate ocean tide modeling in southeast Alaska and large tidal dissipation around Glacier Bay

An accurate prediction of ocean tides in southeast Alaska is achieved using a regional, barotropic ocean model with a finite difference scheme. The model skill is verified by the observational tidal harmonics in southeast Alaska including Glacier Bay. The result is particularly improved in Glacier Bay compared to the previous model of Foreman et al. (2000). We re-estimate tidal energy dissipation in the Alaska Panhandle, and suggest the tidal energy dissipation of 3.5 GW associated with the M2 constituent that is 1.5 times as much as the estimation of Foreman et al. (2000). Large portion of the M2 energy budget entering through Chatham Strait is dissipated in the vicinity of Glacier Bay.
