It is desired to construct a numerical prediction model of the physical processes of circulation in a fjord estuary. A brief review of meteorological and oceanographic modeling techniques is given. The importance of special coordinate systems and choice of grid schemes are discussed. The review of previous modeling work indicates that physical boundaries and the manner in which they are treated are likely to be major new problems to be solved in coastal models. A three dimensional ten layer model is proposed and a set of finite difference equations given. A simplification to a vertical-longitudinal fjord model is made and this set of equations are also given. (Author).

A numerical tidal model using equations developed by Hansen (1952) and Yuen (1967) is automated to the point where the potential user need not undertaken extensive reprogramming. The user adds to the program only those cards needed to specify tides at input points as a function of time; the application of the relevant calculations at each grid point being controlled by an integer matrix that corresponds to the inlet boundary. A sample problem is covered in detail and applications of the model to the M2 tide of the Gulf of California and to a hypothetical mean tide in Cook Inlet are shown. (Author).

Surface drifters were released in the Beaufort Sea near Prudhoe Bay, Alaska for two years (1979-82). The releases were made under the shorefast ice just prior to summer breakup of the ice and in leads in the pack ice. The drifter recoveries indicate that the winds play a significant role in the surface circulation during the open water season. A significant number of drifters beached 'onshore' of their release sites. 'Preferred' beaching areas are identified from the drifter recoveries. All these results indicate the strong possibility that oil released offshore in the Beaufort Sea will impact the North Alaska Coast.
