Southern Ocean evidence for recurring West Antarctic Ice Sheet destabilization during Marine Isotope Stage 11 [PDF]
Nature CommunicationsMillennial-scale deoxygenation of Antarctic Bottom Water (AABW) in the Atlantic Southern Ocean during past interglacials was linked to West Antarctic Ice Sheet (WAIS) melt-driven suppression of dense water formation along the Antarctic margin.

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 ...

Ocean deoxygenation, a paleo-proxy perspective
, 2017 The 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.

Fundamentally different global marine nitrogen cycling in response to severe ocean deoxygenation. [PDF]
Proc Natl Acad Sci U S A, 2019 The present-day marine nitrogen (N) cycle is strongly regulated by biology. Deficiencies in the availability of fixed and readily bioavailable nitrogen relative to phosphate (P) in the surface ocean are largely corrected by the activity of diazotrophs ...

Resilience of Tropical Ecosystems to Ocean Deoxygenation [PDF]
Trends in Ecology & Evolution, 2021 The impacts of ocean deoxygenation on biodiversity and ecosystem function are well established in temperate regions, and here we illustrate how the study of hypoxia in tropical ecosystems can offer insights of general importance. We first describe how mechanisms of resilience have developed in response to naturally occurring hypoxia across three ...

Ocean deoxygenation, the global phosphorus cycle and the possibility of human-caused large-scale ocean anoxia. [PDF]
Philos Trans A Math Phys Eng Sci, 2017 The major biogeochemical cycles that keep the present-day Earth habitable are linked by a network of feedbacks, which has led to a broadly stable chemical composition of the oceans and atmosphere over hundreds of millions of years.

Unique ocean circulation pathways reshape the Indian Ocean oxygen minimum zone with warming [PDF]
Biogeosciences, 2023 The global ocean is losing oxygen with warming. Observations and Earth system model projections, however, suggest that this global ocean deoxygenation does not equate to a simple and systematic expansion of tropical oxygen minimum zones (OMZs).

Frontiers in Marine Science, 2023 Oceanic dissolved oxygen (DO) decline in the Indian Ocean has profound implications for Earth’s climate and human habitation in Eurasia and Africa. Owing to sparse observations, there is little research on DO variations, regional comparisons, and its ...

Glacial CO2 decrease and deep-water deoxygenation by iron fertilization from glaciogenic dust [PDF]
Climate of the Past, 2019 Increased accumulation of respired carbon in the deep ocean associated with enhanced efficiency of the biological carbon pump is thought to be a key mechanism of glacial CO2 drawdown.
