Ocean deoxygenation is the reduction of the oxygen content in different parts of the ocean due to human activities. [ 2 ] [ 3 ] There are two areas where this occurs. Firstly, it occurs in coastal zones where eutrophication has driven some quite rapid (in a few decades) declines in oxygen to very low levels. [ 2 ]
The direction and magnitude of the effects of ocean acidification, warming and deoxygenation on the ocean has been quantified by meta-analyses, [136] [142] [143] and has been further tested by mesocosm studies. The mesocosm studies simulated the interaction of these stressors and found a catastrophic effect on the marine food web, namely, that ...

Climate change is going to wreak havoc on the world’s oceans, according to two new studies, depleting the warming waters of the oxygen that fish and other sea life need to survive.
While satellites and offshore buoys can inform scientists about marine heat waves, the effects on ocean species are less understood. As heat waves warm the Pacific Ocean, effects on marine life ...
Overview of climatic changes and their effects on the ocean. Regional effects are displayed in italics. [1] This NASA animation conveys Earth's oceanic processes as a driving force among Earth's interrelated systems. There are many effects of climate change on oceans. One of the most important is an increase in ocean temperatures.
Global map of low and declining oxygen levels in the open ocean and coastal waters, 2009. [1] The map indicates coastal sites where anthropogenic nutrients have exacerbated or caused oxygen declines to <2 mg/L (<63 μmol/L) (red dots), as well as ocean oxygen minimum zones at 300 m (blue shaded regions).
The effects of ocean warming also include marine heatwaves, ocean stratification, deoxygenation, and changes to ocean currents. [3]: 10 The ocean is also acidifying as it absorbs carbon dioxide from the atmosphere. [4] The primary causes [5] and the wide-ranging impacts [6] [7] [3]: 3–36 of climate change.
