WebThese regions, so called oxygen minimum zones (OMZ) are characteriz ed by low oxygen concentrations spanning a depth range of about 200 -700 m depth (e.g. Karstensen et al. 2008). 10 It is well established that OMZs a + ect marine biogeochemical processes such as the global carbon and nutrient cycles (Bange et al. , 2005; Naqvi e t al., 2006). … WebImpacts of the oxygen deficiency on regional biogeochemistry, especially anaerobic nitrogen transformaions, are described. A comparison of the perrenial, mesopelagic OMZ in the open Northwestern Indian Ocean is made with a shallower oxygen deficient system that develops seasonally (during late summer and autumn) over the western Indian shelf.
