Tidal Water and Ice Dynamics in the Arctic Ocean
To model the tides of the Arctic Ocean, one uses a two-dimensional non-linear model for water, which takes into account the effects of astronomical factors, the Atlantic and the Pacific Oceans, the earth's tides, the effects of loading and self-gravitations, and a non-linear model of ice drift,...

To model the tides of the Arctic Ocean, one uses a two-dimensional non-linear model for water, which takes into account the effects of astronomical factors, the Atlantic and the Pacific Oceans, the earth's tides, the effects of loading and self-gravitations, and a non-linear model of ice drift, which allows internal stresses in the ice cover. At the interface of two media, the friction, proportional to the second power of the difference between the water and ice velocities, is prescribed. The calculations of the propagation of diurnal (Kl, 01) and semi-diurnal (M2, S2) waves of the tidal potential are given. The accuracy of the modeling was estimated at 94 points at the coast. Mean square root errors in calculating the amplitude were 0.054, 0.023, 0.013 and 0.014 m, and 26 deg, 15 deg, 28 deg and 30 deg for the phase of the M2, S2, K1, 01 waves, respectively.
