Microbial oceanography of anoxic oxygen minimum zones.
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 (N(2)) and nitrous oxide (N(2)O) gases. Anaerobic microbial processes, including the two pathways of N(2) production, d...

متن کاملEffects of hypoxia on habitat quality of pelagic planktivorous fishes in the northern Gulf of Mexico
To evaluate the impact of hypoxia (<2 mg O2 l−1) on habitat quality of pelagic prey fishes in the northern Gulf of Mexico, we used a spatially explicit, bioenergetics-based growth rate potential (GRP) model to develop indices of habitat quality. Our focus was on the pelagic bay anchovy Anchoa mitchilli and Gulf menhaden Brevoortia patronus. Positive GRP was considered high-quality habitat (HQH)...
متن کاملOxygen minimum zone expansion in the eastern tropical North Pacific during deglaciation
[1] During deglaciation at 17 ka the intensity and footprint of the oxygen minimum zone (OMZ) increased in the Eastern Tropical North Pacific (ETNP) before a subsequent expansion on the California Margin. Evidence for the earlier increase is found in trace metal concentrations, lamination preservation and dN values from cores located between 540–750 m water depth in the Gulf of Tehuantepec, Sou...
