Ocean deoxygenation is the process by which oxygen levels in the ocean decrease, leading to the formation or expansion of areas known as oxygen minimum zones (OMZs). OMZs are regions in the ocean where dissolved oxygen concentrations are at their lowest, often reaching levels that are insufficient to support marine life.

The given statement is incorrect. Ocean deoxygenation does not refer to the maximum reduction of OMZs, but rather to the overall decrease in oxygen levels in the ocean as a result of various factors, including climate change, pollution, and nutrient runoff. The expansion of OMZs is one of the consequences of this deoxygenation process.

  • Ocean deoxygenation is the expansion of oxygen minimum zones in the world’s oceans as a consequence of anthropogenic emissions of carbon dioxide. 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.
  • Ocean deoxygenation poses implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitats.
  • Most of the excess heat from CO2 and other greenhouse gas emissions is absorbed by the oceans. Warmer oceans cause deoxygenation both because oxygen is less soluble in warmer water, and through temperature driven stratification of the ocean which inhibits the production of oxygen from photosynthesis.
  • Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen and are a more severe condition of hypoxia.
