Ocean deoxygenation is an additional stressor on marine life. Ocean deoxygenation is the expansion of oxygen minimum zones in the oceans as a consequence of burning fossil fuels. Along with this ocean deoxygenation is caused by an imbalance of sources and sinks of oxygen in dissolved waterLaffoley, D. & Baxter, J.M. (eds.) (2019). Ocean deoxygenation: Everyone’s problem - Causes, impacts, consequences and solutions. Full report. Gland, Switzerland: IUCN. . Burning fossil fuels consumes oxygen, but because of the large atmospheric oxygen inventory, the associated relative decline of atmospheric oxygen (0.001\% per year) is about two orders of magnitude smaller than the current rate of ocean deoxygenation. The change has been fairly rapid and poses a threat to fish and other types of marine life, as well as to people who depend on marine life for nutrition or livelihood.Oceans suffocating as huge dead zones quadruple since 1950, scientists warn The Guardian, 2018Ocean's Oxygen Starts Running LowFinding forced trends in oceanic oxygenHow global warming is causing ocean oxygen levels to fall Ocean deoxygenation poses implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitats. Ocean deoxygenation poses implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitats. Total ocean oxygen content has decreased by 1-2\% since 1960.
