Oceanic upwelling and productivity in the eastern tropical Pacific [PDF]

open access: yesLimnology and Oceanography, 1991
An oceanographic survey of the eastern tropical Pacific Ocean in August-November 1990 found a productive, nutrient-rich, moderately high-chlorophyll surface layer in two oceanic upwelling regions: the equatorial divergence, especially east of the Galapagos, and the countercurrent divergence out to 105”W, > 1,000 km west of the Costa Rica1 Dome ...
