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 ...

Microbial responses to ocean deoxygenation: Revisiting the impacts on organic carbon cycling [PDF]
iScienceSummary: Ocean deoxygenation is impacting and will also in the future impact fundamental biogeochemical cycles. This review explores the ecological functions of microbes under hypoxic and anoxic conditions, emphasizing their critical roles in carbon ...

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.

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.

Microbial Respiration, the Engine of Ocean Deoxygenation
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.

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.

Competing effects of wind and buoyancy forcing on ocean oxygen trends in recent decades [PDF]
Nature CommunicationsOcean deoxygenation is becoming a major stressor for marine ecosystems due to anthropogenic climate change. Two major pathways through which climate change affects ocean oxygen are changes in wind fields and changes in air-sea heat and freshwater fluxes.

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 hypoxia: The science of climate change in the sea [PDF]
Scientific ReportsThe oxygen inventory of the global ocean is declining. This phenomenon, known as ocean deoxygenation, has emerged as a fundamental pathway for climate change to alter marine ecosystems. An important concern is how this global oxygen decline will manifest
