1. Introduction The horizontal resolution of modern ocean models has increased significantly over the past decade. Model resolution of 3 km for global- and basin-scale domains and as high as 1 km to 500 m for coastal applications are not uncommon. At the same time ocean observing platforms have begun to provide high-resolution observations of near-surface currents (HF radar; Paduan and Graber 1997 ), subsurface temperature and salinity profiles (gliders; Rudnick et al. 2004 ), and, in the

to vertical advection and turbulent diffusion only, but is still able to produce a good approximation to the evolution of the atmosphere when compared to the full version, and is therefore adequate for the purposes of this study. The surface pressure, vertical velocity, tendencies due to horizontal advection, and geostrophic wind components are prescribed externally. The ocean component describes the evolution of the mean values of temperature, salinity, and zonal and meridional currents on a

; Segschneider et al. 2000 ) it was not introduced into operational use because there were still some open issues. First, altimeter information on its own is not enough to reconstruct the thermal and salinity fields but needs to be combined with in situ data. Combining altimeter and in situ is not straightforward, however, and the previously proposed approach exposed some problems (see section 2 ). Second, the altimeter actually measures sea level anomalies. The development of gravity missions such as the

essentially adiabatic. Ocean simulation, in contrast, requires the accurate modeling of thermodynamics. If one adopts potential density as a vertical coordinate, as isopycnal models do, then the vertical coordinate is cast as a function of the two quantities potential temperature, θ, and salinity, S. Both of these are conservative quantites and in the absence of mixing, fluid parcels are required by construction to move on isopycnal surfaces. Recent direct measurements of diapycnal flux made during

involving tur- bulence, rate of surface cooling, rate at which solar radiation penetrates the surface, rate of vertical dis-tribution of temperature and salinity, and rate of verticalflow of the water. Methods have been worked out for applying these equations to numerical data, without the need of theirgeneral solut,ion, which has not been attempted. Threeintegrals appearing in these equations and depending upon the vertical variation of specific gravity havebeen tabulated to facilitate numerical

decrease as the ice cover grows andthe modifying influence of the open water diminishes.Freeze-up models may be used to study the consequences of man-made changes such as the James Bayhydroelectric project (diversion and regulation ofriver outflow). This will affect the salinity of Hudsonand James Bays and may have climatic effects dueto changes in the ice regime.
