Ocean deoxygenation after the Sturtian Snowball [PDF]
Nature CommunicationsThe abrupt ending of the Sturtian ‘Snowball’ glaciation was characterised by enhanced chemical weathering and carbon cycle perturbations, but there is less certainty over how oxygen levels responded to those changes.

A Selected Review of Impacts of Ocean Deoxygenation on Fish and Fisheries
Fishes, 2023 Oxygen is crucial for the survival of marine species. Yet, the ocean has experienced a loss of approximately 2% of its oxygen inventory since the last century, resulting in adverse impacts on marine life and ecosystems.

Microbial Respiration, the Engine of Ocean Deoxygenation [PDF]
Frontiers in Marine Science, 2019 Microbial plankton respiration is the key determinant in the balance between the storage of organic carbon in the oceans or its conversion to carbon dioxide with accompanying consumption of dissolved oxygen.

Simulations of ocean deoxygenation in the historical era: insights from forced and coupled models
Frontiers in Marine Science, 2023 Ocean deoxygenation due to anthropogenic warming represents a major threat to marine ecosystems and fisheries. Challenges remain in simulating the modern observed changes in the dissolved oxygen (O2).

Ocean deoxygenation dampens resistance of diatoms to ocean acidification in darkness
Frontiers in Marine ScienceRespiratory activity in the oceans is declining due to the expansion of hypoxic zones and progressive deoxygenation, posing threats to marine organisms along with impacts of concurrent ocean acidification. Therefore, understanding the combined impacts of

Evidences and drivers of ocean deoxygenation off Peru over recent past decades [PDF]
Scientific Reports, 2021 Deoxygenation is a major threat to the coastal ocean health as it impacts marine life and key biogeochemical cycles. Understanding its drivers is crucial in the thriving and highly exploited Peru upwelling system, where naturally low-oxygenated ...

Frontiers in Marine Science, 2021 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.

Ocean deoxygenation linked to ancient mesopelagic fish decline
Communications Earth & EnvironmentMesopelagic fish are integral to ocean food webs and play an important role in carbon transport through their vertical migration behavior. Ocean deoxygenation caused by anthropogenic warming is expected to pose severe threats to mesopelagic fauna by ...
