Ocean Deoxygenation in a Warming World
Annual Review of Marine Science, 2010Ocean warming and increased stratification of the upper ocean caused by global climate change will likely lead to declines in dissolved O 2 in the ocean interior (ocean deoxygenation) with implications for ocean productivity, nutrient cycling, carbon cycling, and marine habitat.

Ocean deoxygenation: Time for action
Science, 2018In their Review “Declining oxygen in the global ocean and coastal waters” (5 January, p. [46][1]), D. Breitburg et al. summarize evidence showing that oxygen has declined in the open ocean and in coastal waters over the past 50 years as a result of increased greenhouse gas emissions and ...

Drivers and mechanisms of ocean deoxygenation
Nature Geoscience, 2018Direct observations indicate that the global ocean oxygen inventory is decreasing. Climate models consistently confirm this decline and predict continuing and accelerating ocean deoxygenation. However, current models (1) do not reproduce observed patterns for oxygen changes in the ocean’s thermocline; (2) underestimate the temporal variability of ...

Manifestation, Drivers, and Emergence of Open Ocean Deoxygenation
Annual Review of Marine Science, 2018Oxygen loss in the ocean, termed deoxygenation, is a major consequence of climate change and is exacerbated by other aspects of global change. An average global loss of 2% or more has been recorded in the open ocean over the past 50–100 years, but with greater oxygen declines in intermediate waters (100–600 m) of the North Pacific, the East Pacific ...

Large-scale ocean deoxygenation during the Paleocene-Eocene Thermal Maximum
Science, 2018Fishin' gone? Because gas solubility decreases as temperatures increase, global warming is likely to cause oxygen loss from the oceans. This could have a detrimental impact on fish populations, the fishing industry, and global food availability. Have such impacts occurred before? Yao et al.

A climate threshold for ocean deoxygenation during the Early Cretaceous
NatureOceanic anoxic events (OAEs) are historical intervals of global-scale ocean deoxygenation associated with hyperthermal climate states and biological crises1,2. Massive volcanic carbon dioxide (CO2) emissions frequently associated with these events are thought to be a common driver of ocean deoxygenation through several climate-warming-related ...

Coral reef survival under accelerating ocean deoxygenation
Nature Climate Change, 2020Global warming and local eutrophication simultaneously lower oxygen (O2) saturation and increase biological O2 demands to cause deoxygenation. Tropical shallow waters, and their coral reefs, are particularly vulnerable to extreme low O2 (hypoxia) events. These events can drive mass mortality of reef biota; however, they currently remain unaccounted for

Ocean deoxygenation, a paleo-proxy perspective
2023The oceans are losing oxygen because of global warming and the consequences of this ocean deoxygenation are far reaching, particularly for aerobic marine organisms that depend on dissolved oxygen to live. Furthermore, in oxygen-deficient waters, ocean deoxygenation promotes global warming through the microbial production of nitrous oxide, a powerful ...
