Emerging Global Ocean Deoxygenation Across the 21st Century

open access: yesGeophysical Research Letters, 2021
Ocean 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 ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Investigating the role that the Southern Ocean biological pump plays in determining global ocean oxygen concentrations and deoxygenation [PDF]

open access: yes, 2013
Global ocean circulation connects marine biogeochemical cycles through the long-range transport of nutrients and oxygen with the Southern Ocean (SO) acting as a water mass crossroads. The biological pump in the SO has been shown to play an important role

The effects of changing climate on faunal depth distributions determine winners and losers

open access: yes, 2015
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

A novel global gridded ocean oxygen product derived from a neural network emulator and in-situ observations [PDF]

open access: yesEarth System Science Data
Ocean deoxygenation, driven by climate change, poses significant challenges to marine ecosystems and can profoundly alter nutrient and carbon cycling.

Degrees of reversibility of ocean deoxygenation in an atmospheric carbon dioxide removal scenario

open access: yesEnvironmental Research Letters
Over the last century, increasing atmospheric carbon dioxide (CO2) concentrations, among other greenhouse gases, and resulting climate change have greatly impacted the ocean.

Palaeo-records of histories of deoxygenation and its ecosystem impact

open access: yes, 2019
Coral reefs are suffering unprecedented declines worldwide. Most studies focus on stressors such as rising temperatures, nutrient pollution, overfishing, and ocean acidification as drivers of this degradation.

Towards an integrated Global Ocean Acidification Observation Network [PDF]

open access: yes, 2009
The autonomous measurement of dissolved carbon dioxide (CO2) is of great and still increasing importance for addressing many scientific as well as socio-economic questions.

Climate change-accelerated ocean biodiversity loss & associated planetary health impacts

open access: yesThe Journal of Climate Change and Health, 2022
A planetary health perspective views human health as a function of the interdependent relationship between human systems and the natural systems in which we live.

Redox-controlled restructuring of marine microbial ecosystems during oceanic anoxic events

open access: yesProgress in Earth and Planetary Science
During the Phanerozoic, the ocean repeatedly experienced periods of widespread deoxygenation known as oceanic anoxic events. Geological records from these events indicate a profound shift in marine microbial ecosystems.
