Oxygen minimum zones (OMZs) in the modern ocean

2009-3-1  1.. IntroductionThe interest in oxygen minimum zones (OMZs), characterized herein as O 2-deficient layers in the ocean water column, is quite recent, since the appearance of the name “OMZ” in Cline and Richards (1972).OMZs correspond to subsurface oceanic zones (e.g., at 50–100 m depth in the Arabian Sea; Morrison et al., 1999) and reaching ultra-low values of O 2 concentration (e.g. <1

Recent modeling studies also highlight the important role of submesoscale to mesoscale dynamics in constraining the upper OMZ meridional boundaries

Revising the nitrogen cycle in the Peruvian oxygen

2009-3-24  The oxygen minimum zone (OMZ) of the Eastern Tropical South Pacific (ETSP) is 1 of the 3 major regions in the world where oceanic nitrogen is lost in the pelagic realm. The recent identification of anammox, instead of denitrification, as the likely prevalent pathway for nitrogen loss in this OMZ raises strong questions about our understanding of nitrogen cycling and organic matter

The Humboldt Current System: Ecosystem components

The interplay between atmospheric variability, the poleward undercurrent, the shallow oxygen minimum zone (OMZ), and the fertilizing effect of coastal upwelling and overall high primary production rates drive bio-physical interactions, the carbon biomass, and fluxes of gases and particulate and dissolved matter through the water column.

Microbial oceanography of anoxic oxygen minimum zones

2012-10-2  Vast expanses of oxygen-deficient and nitrite-rich water define the major oxygen minimum zones (OMZs) of the global ocean. They support diverse microbial communities that influence the nitrogen economy of the oceans, contributing to major losses of fixed nitrogen as dinitrogen (N2) and nitrous oxide (N2O) gases. Anaerobic microbial processes, including the two pathways of N2
