Cryptic oxygen cycling in anoxic marine zones.
Oxygen availability drives changes in microbial diversity and biogeochemical cycling between the aerobic surface layer and the anaerobic core in nitrite-rich anoxic marine zones (AMZs), which constitute huge oxygen-depleted regions in the tropical oceans. The current paradigm is that primary production and nitrification within the oxic surface layer fuel anaerobic processes in the anoxic core o...
متن کاملMicrobial 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 کاملMeta-omic signatures of microbial metal and nitrogen cycling in marine oxygen minimum zones
Iron (Fe) and copper (Cu) are essential cofactors for microbial metalloenzymes, but little is known about the metalloenyzme inventory of anaerobic marine microbial communities despite their importance to the nitrogen cycle. We compared dissolved O2, NO[Formula: see text], NO[Formula: see text], Fe and Cu concentrations with nucleic acid sequences encoding Fe and Cu-binding proteins in 21 metage...
متن کاملNew twist on nitrogen cycling in oceanic oxygen minimum zones.
L arge uncertainties in the future of Earth’s climate have intensified research on the global biogeochemical cycles on land and in the sea. The ocean ecosystem is critical in the carbon balance between the atmosphere and deep ocean, but also plays a large role in chemical and nutrient fluxes that maintain oceanic productivity and greenhouse gas fluxes to and from the atmosphere. Particularly re...
