This is the expression derived by Sverdrup (1947).

This solution (Fofonoff, 1962) does not provide for an eastern boundary layer. Fofonoff 

 has justified the elimination of an eastern boundary layer by writing Munk's (1950) general 

 solution for mass transport in a nondimensional form and simplifying the equation on the 

 basis of relative orders of magnitude. For the area under consideration (the central 

 North Pacific Ocean) provision for an eastern boundary layer is not necessary. 



As mentioned above Sverdrup (1947), Munk (1950), and Fofonoff (1962) all specified 

 that the transport was made up of baroclinic and Ekman modes only: the problem of 

 treating convergence due to bathymetric effects on the barotropic flow thus was not 

 pertinent. 



Fofonoff (1960) used equation (28) (in geographic coordinates) as the basis for his 

 mass transport computations in the Pacific. Using monthly means of sea-level atmos- 

 pheric pressure (from the records of the U.S. Weather Bureau) he successively computed: 



geostrophic wind velocities, 



surface wind velocities, 



wind stress on the surface, 



meridional and zonal Ekman transport, Vg and Ug, 



meridional total transport, V, 



integrated total transport, i//, and 



integrated geostrophic transport, ipg- 



The pressure distribution and each of the components or modes of transport are tabulated 

 on alternate five-degree grid points for the Pacific Ocean north of latitude 20°N. Tabu- 

 lations have been published for each month during the period January 1950 through May 

 1962 (Fofonoff 1960, 1961; Fofonoff and Ross, 1962: Fofonoff and Dobson. 1963). Similar 

 tabulations have been made for months of interest during the period June 1962 through
