Journal ArticleDOI

Denise L. Breitburg,Lisa A. Levin,Andreas Oschlies,Marilaure Grégoire,Francisco P. Chavez,Daniel J. Conley,Véronique Garçon,Denis Gilbert,Dimitri Gutiérrez,Kirsten Isensee,Gil S. Jacinto,Karin E. Limburg,Ivonne Montes,S. W. A. Naqvi,Grant C. Pitcher,Grant C. Pitcher,Nancy N. Rabalais,Michael R. Roman,Kenneth A. Rose,Brad A. Seibel,Maciej Telszewski,Moriaki Yasuhara,Jing Zhang +22 more
TL;DR: Improved numerical models of oceanographic processes that control oxygen depletion and the large-scale influence of altered biogeochemical cycles are needed to better predict the magnitude and spatial patterns of deoxygenation in the open ocean, as well as feedbacks to climate.
Journal ArticleDOI
Revising the nitrogen cycle in the Peruvian oxygen minimum zone
Phyllis Lam,Gaute Lavik,Marlene Mark Jensen,Jack van de Vossenberg,Markus Schmid,Dagmar Woebken,Dimitri Gutiérrez,Rudolf Amann,Mike S. M. Jetten,Marcel M. M. Kuypers +9 more
TL;DR: It is shown that in the ETSP-OMZ, anammox obtains 67% or more of NO2− from nitrate reduction, and 33% or less from aerobic ammonia oxidation, based on stable-isotope pairing experiments corroborated by functional gene expression analyses.
Journal ArticleDOI
Anaerobic ammonium oxidation in the Peruvian oxygen minimum zone
M. Robert Hamersley,Gaute Lavik,Dagmar Woebken,Jayne E. Rattray,Phyllis Lam,Ellen C. Hopmans,Jaap S. Sinninghe Damsté,Siegfried Krüger,Michelle Graco,Dimitri Gutiérrez,Marcel M. M. Kuypers +10 more
TL;DR: At the time and locality of this study, anammox, rather than denitrification, was responsible for N2 production in the Peruvian OMZ waters.
Journal ArticleDOI
Benthic processes on the Peru margin: a transect across the oxygen minimum zone during the 1997–98 El Niño
Lisa A. Levin,Dimitri Gutiérrez,Anthony E. Rathburn,Carlos Neira,Javier Sellanes,Práxedes Muñoz,Victor A. Gallardo,Marco Salamanca +7 more
TL;DR: The taxa most tolerant of nearly anoxic, organic-rich conditions within the Peru OMZ were calcareous foraminifera, nematodes and gutless phallodrilinid (symbiont-bearing) oligochaetes, and many other macrofaunal taxa increased in relative abundance below the OMZ.
Journal ArticleDOI
Biological and chemical consequences of the 1997-1998 El nino in the Chilean coastal upwelling system: a synthesis

TL;DR: A summary of the information available on the physical, chemical, and biological responses of the Chilean upwelling zone resulting from the strong 1997-1998 EN event is presented in this paper.
