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 …

Nitrous oxide (N2O) is an environmentally important atmospheric trace gas because it is an
effective greenhouse gas and it leads to ozone depletion through photo-chemical nitric …

In the modern ocean, oxygen minimum zones (OMZs) are potential traces of a primitive
ocean in which Archean bacteria lived and reduced chemical anomalies occurred. But …

We review here the available information on methane (CH 4) and nitrous oxide (N 2 O) from
major marine, mostly coastal, oxygen (O 2)-deficient zones formed both naturally and as a …

Simultaneous characterization of taxonomic composition, metabolic gene content and gene
expression in marine oxygen minimum zones (OMZs) has potential to broaden perspectives …

We quantified the removal of fixed nitrogen as N2 production by anammox and N2 and N2O
production by denitrification over a distance of 1900 km along the coasts of Chile and Peru …

In the Humboldt Current System (HCS), biological and non-biological components,
ecosystem processes, and fisheries are known to be affected by multi-decadal, inter-annual …

Nitrogen fixation is an essential process that biologically transforms atmospheric dinitrogen
gas to ammonia, therefore compensating for nitrogen losses occurring via denitrification and …

We use transient time distributions calculated from tracer data together with in situ
measurements of nitrous oxide (N2O) to estimate the concentration of biologically produced …

Background Oxygen minimum zones (OMZs) are expanding in the World Ocean as a result
of climate change and direct anthropogenic influence. OMZ expansion greatly affects …
