Figure F7. A. Ekman velocity from satellite scatterometer measurements. B. Geostrophic currents from Topex/Poseidon. C. The sum of the currents box superimposed upon sea-surface temperature anomalies (SSTA). The surface currents in the vicinity of Site 1243 (OSN-2) are ~1 kt. The Equatorial Countercurrent is well to the south. QuikSCAT data courtesy of M. Bourassa, Center for Ocean-Atmospheric Prediction Studies/Florida State University.
