Here, I compare the Sverdrup pressure --geostrophic transport streamfunction-- with the observed integrated geostrophic transport. The Sverdrup pressure and transport is the Sverdrup transport minus the Ekman transport. The pressure is found from:

dP/dx = fV + Tau-x = (f/B)Curl(Tau) + Tau-x = (f²/B)Curl(Tau/f),

where upper-case symbols indicate vertically-integrated quantities (V,P) and B=Beta (factors of rho0 have been dropped for simplicity). The eastern boundary condition is no flow: At a meridional coast U=0, so dP/dx=Tau-x; at a zonal coast dP/dy=Tau-y. These two are integrated northward along the coast (assume P=0 at 30°S at the coast) and then the resulting P0(y) is the eastern BC for the westward integration. The Sverdrup zonal geostrophic transport is (-1/f)dP/dy, which can be compared with the transport obtained from the XBTs.

Hope I didn't over-simplify this.
