Figure F4. Paleopositions of sites along the 56-Ma Leg 199 transect, superimposed on model estimates of upwelling from a new early Eocene coupled ocean-atmosphere climate model (Huber, this volume). Lines with arrows = current streamlines at the approximate depth of the thermocline. Compare the upwelling pattern in this model with the chlorophyll distribution in Figure F2 an indicator of modern upwelling.
