Anaerobic oxidation of ammonium (anammox) in oxygen minimum zones (OMZs) is a major pathway of oceanic nitrogen loss. Ammonium released from sinking particles has been suggested to fuel this process. During cruises to the Peruvian OMZ in April–June 2017 we found that anammox rates are strongly...
In certain highly productive regions, respiration of organic matter below the euphotic zone can be so intense that oxygen minimum zones (OMZs) develop. Upon oxygen depletion in the OMZs, NO3À becomes thermodynamically the most favorable electron acceptor for the respiration of organic matter that...
In the Indian Ocean, mid-depth oxygen minimum zones (OMZs) occur in the Arabian Sea and the Bay of Bengal. The lower part of the Arabian-Sea OMZ (ASOMZ; below 400 m) intensifies northward across the basin; in contrast, its upper part (above 400 m) is located in the central/eastern...

The positive feedback between oxygen levels in atmosphere and primary productivity caused progressive oxygenation in ocean–atmosphere system and enable phosphorites to be formed by different mechanisms. Results show that the Lower Doushantuo consist of abiotic intraclasts and exhibited “seawater-like” ...

Additionally, microvascular endothelial cells are involved in modulating the exchange of molecules, regulation of immun...

Microbial communities in oxygen minimum zones (OMZs) are known to have significant impacts on global biogeochemical cycles, but viral influence on microbial processes in these regions are much less studied. Here we provide baseline ecological patterns using microscopy and viral metagenomics from the Eas...
