Abstract
A two-dimensional vertically averaged hydrodynamic model in spherical coordinates with 0.2° latitude, 0.35° longitude resolution was employed to predict the M2 and K1 tidal elevations and currents in the northwestern Gulf of Alaska; 50°N, 145°–168°W to the southern Alaskan coast. Boundary conditions for the model were derived from Schwiderski's global ocean tidal model and observations. Model predictions for the amplitude and phase of the sea elevations are generally within 5 cm and 2° of the observation for the M2 constituent and 7 cm and 5° for the K1. The M2 standing wave pattern in shelikof Strait and the tidal responance in Cook Inlet observed in earlier studies are confirmed by the numerical simulations.Keywords
