As the ocean absorbs excessive anthropogenic CO2 and ocean acidification proceeds, it is thought to be harder for marine calcifying organisms, such as shellfish, to form their skeletons and shells made of calcium carbonate.

Hazards of decreasing marine oxygen: the near-term and millennial-scale benefits of meeting the Paris climate targets [PDF]
Ocean deoxygenation is recognized as key ecosystem stressor of the future ocean and associated climate-related ocean risks are relevant for current policy decisions.

Ocean Acidification Amplifies Multi-Stressor Impacts on Global Marine Invertebrate Fisheries
Elevated atmospheric carbon dioxide (CO2) is causing global ocean changes and drives changes in organism physiology, life-history traits, and population dynamics of natural marine resources.

Major environmental drivers determining life and death of cold-water corals through time.
Cold-water corals (CWCs) are the engineers of complex ecosystems forming unique biodiversity hotspots in the deep sea. They are expected to suffer dramatically from future environmental changes in the oceans such as ocean warming, food depletion ...

Tropical deoxygenation sites revisited to investigate oxygen and nutrient trends [PDF]
An oxygen decrease of the intermediate-depth low-oxygen zones (300 to 700 m) is seen in time series for selected tropical areas for the period 1960 to 2008 in the eastern tropical Atlantic, the equatorial Pacific and the eastern tropical Indian Ocean ...

Irreversible loss in marine ecosystem habitability after a temperature overshoot
Anthropogenic warming of the oceans and associated deoxygenation are altering marine ecosystems. Current knowledge suggests these changes may be reversible on a centennial timescale at the ocean surface but irreversible at deeper depths even if global ...

Remineralisation changes dominate oxygen variability in the North Atlantic [PDF]
Oxygen is fundamental to ocean biogeochemical processes, with deoxygenation potentially reducing biodiversity, and disrupting biogeochemical cycles.

Geoengineered Ocean Vertical Water Exchange Can Accelerate Global Deoxygenation [PDF]
AbstractOcean deoxygenation is a threat to marine ecosystems. We evaluated the potential of two ocean intervention technologies, that is, “artificial downwelling (AD)” and “artificial upwelling (AU),” for remedying the expansion of Oxygen Deficient Zones (ODZs).

Emerging Global Ocean Deoxygenation Across the 21st Century [PDF]
AbstractOcean deoxygenation (i.e., loss of oxygen) due to climate change can result in marine environment deterioration. Here we applied a time of emergence method to detect when and where the signals of oceanic oxygen change would emerge from its internal variability in the epipelagic, mesopelagic, and bathypelagic zones.

Reviews and syntheses: Biological indicators of low-oxygen stress in marine water-breathing animals [PDF]
Anthropogenic warming and nutrient over-enrichment of our oceans have resulted in significant, and often catastrophic, reductions in dissolved oxygen (deoxygenation).
