Figure F1. Map of the TEP showing major surface currents. The locations of ODP Sites 851 and 1241 and their plate tectonic backtracks (in 1-m.y. steps) are indicated. Solid dots = modern position, open dots = paleopositions of these sites at 6 Ma. NEC = North Equatorial Current, NECC = North Equatorial Counter Current, EUC = Equatorial Under Current, SEC = South Equatorial Current, PCC = Peru–Chile Current.
