A part of the continental shelf area of the Bering and Chukchi Sea are now being opened up for oil exploration. For engineering and ecological risk analyses, extensive field data collection efforts are being carried out by various United States agencies and petroleum corporations to understand the hydrodynamic behavior of this vast offshore area. In addition, modeling studies are being made for which a three-dimensional model of the area, outlined in Fig. 1, has been developed. This model is dynamically coupled to a two-dimensional stochastic weather model. This weather model contains a Markov synoptic component and a storm track component. The parameters of this model are derived from a 20-year data base. This paper presents a description of the three-dimensional model and the results of a series of simulations using the model to compute tidal propagation and circulations induced by tides and wind. The results of a simulation of a moving storm through the eastern Bering Sea are also presented.

This paper presents the development of a three dimensional model of the Gulf of Alaska. The model extends between the Vancouver Island and the Aleutian Islands covering approximatedly 1.5 million square kilometers over the northern Pacific Ocean. Formulated on an ellipsoidal horizontal grid and variable vertical grid, the model is schematized over a 81 x 53 x 10 grid structure. The solution scheme is implicit over the vertical and is programmed using one-dimensional dynamic array for the efficient use of machine storage. The turbulence closure scheme for the non-homogeneous vertical shear is formulated so that the potential and kinetic energetics are monitored and transferred in a closed form. The hydrodynamic model is coupled to a two-dimensional stochastic weather model and an oil-spill trajectory/weathering model. The former also simulates stochastically the cyclogenetic/cyclolytic processes within the modeled area. The paper also compares the computed results with the available field data. Good agreements are found in tidal amplitude and phases as well as currents.
