Journal ArticleDOI
Mesoscale eddies off Peru in altimeter records: Identification algorithms and eddy spatio-temporal patterns
TL;DR: In this paper, the authors compare two different automated methods for eddy identification: the geometrical or "winding-angle method" and the commonly-used Okubo-Weiss algorithm.
Journal ArticleDOI
The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx): goals, platforms, and field operations

TL;DR: The VAMOS(1) Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) was an international field program designed to make observations of poorly understood but critical components of the coupled climate system of the southeast Pacific as discussed by the authors.
Journal ArticleDOI
Vertical structure of mesoscale eddies in the eastern South Pacific Ocean: A composite analysis from altimetry and Argo profiling floats
TL;DR: In this paper, the mean vertical structure of mesoscale eddies in the Peru-Chile Current System is investigated by combining the historical records of Argo float profiles and satellite altimetry data.
Journal ArticleDOI
Eddy activity in the four major upwelling systems from satellite altimetry (1992-2007)
TL;DR: In this article, the authors investigated eddy activity in the four major eastern boundary upwelling systems (EBUS) using 15 years of satellite altimetry data and found that mesoscale structures are mainly generated along the continental coasts and south of the main archipelagos and propagate westward with velocities increasing toward the equator.
Journal ArticleDOI
Oxygen: A Fundamental Property Regulating Pelagic Ecosystem Structure in the Coastal Southeastern Tropical Pacific
Arnaud Bertrand,Alexis Chaigneau,Salvador Peraltilla,Jesus Ledesma,Michelle Graco,Florian Monetti,Francisco P. Chavez +6 more
TL;DR: It is shown that the effects of oxygen on anchovy and sardine are opposite, suggesting that a key process, the need to breathe, has been neglected previously and allows the development of a comprehensive conceptual model of pelagic fish populations and change in an ocean ecosystem impacted by low oxygen.
