Figure F10. Model of early Eocene equatorial upwelling from Huber (2002), showing global land-sea distribution and annual average upwelling into thermocline (56 Ma sites, fixed-hotspot paleopositions). Red = regions of vigorous upwelling, green to blue = regions of weak upwelling, white = areas of average downwelling. Current streamlines at ~100 m ocean depth are shown for the Pacific Ocean. All map views are projected on a Mollweide projection. Upwelling region in eastern Pacific was broader than that of the modern region, primarily because of secondary upwelling centers on edges of region.
