Research suggests that the southern ocean plays a key role in controlling global oceanic oxygenation. However, the overall trend in ocean oxygen levels is unclear, with some studies indicating deoxygenation and others suggesting increased oxygenation in certain regions. The factors influencing ocean oxygen trends appear to be complex, involving competing effects of wind, buoyancy, and other factors.
