Deoxygenation is the reduction of oxygen levels in seawater, primarily due to ocean warming, which decreases dissolved oxygen. It is exacerbated by increased oxygen consumption, stratification, and reduced water mixing.

Statements
Ocean deoxygenation is the loss of oxygen in ocean waters due to warming, reducing oxygen saturation, and increasing consumption, stratification, and ventilation changes. Human activities, such as nutrient runoff and pollution, have worsened coastal and open-ocean hypoxia, harming marine organisms and shrinking marine habitats.
