Influence of large scale oscillations on upwelling-favorable coastal wind off central Chile

[1] Along the central coast of Chile is typically equatorward, upwelling-favorable wind associated with the southeast Pacific anticyclone. A coastal low-level jet often develops, and its wind speed is mostly controlled by the meridional pressure gradient. While the low-level jet is a mesoscale feature forced by an interaction between synoptic conditions and coastal topography, regional sea leve...

Inter-annual variability of the Pelagic-Benthic coupling in the upwelling system off central Chile

The coastal region of central Chile (36 S) is one of the most productive coastal systems, characterized by a marked seasonality in the upwelling regime, that brings subsurface waters rich in nutrient and poor in oxygen (ESSW) into the euphotic zone. This oceanographic condition depends basically on the equatorward wind strength and is modified on different time scales, with the El Niño-Southern...

Comparison of feeding guild structure and ecomorphology of intertidal fish assemblages from central California and central Chile

The hypothesis of ecological and morphological convergence of the taxonomically distinct intertidal fish assemblages from central California, USA, and central Chile was tested by comparing the feeding guild structures and the morphologies associated with food capture and processing of guild members from each region. We determined the diets of the most abundant intertidal fishes from 3 central C...

Upwelling response to atmospheric coastal jets off Central Chile: A modeling study of the October 2000 event

Managing the Peruvian Upwelling Ecosystem:

A brief review is given of Ibe interrelationships and implications of Ibe findings reported in Ibe contributions included in this volume. Emphasis is given to some questions Ibat now appear crucial, e.g. Ibe cannibalization of anchoveu eggs and biannual cycles in anchoveta recruitment and their possible cause(s). Some suggestions are made for future research on various elements of Ibe Peruvian ...
