 Microbiology of oxygen minimum zones

Microbiology of oxygen minimum zones (OMZs) refers to the study of microbial communities and their activities in areas of the ocean where oxygen levels are significantly reduced compared to surrounding waters. These zones can occur at various depths in the ocean, typically located between 200 and 1,000 meters, and are characterized by low concentrations of dissolved oxygen (often less than 0.5 mL/L or 22 μM).
