Deoxygenation and organic carbon burial in past oceans

, 2021
Within the content of this thesis, I aim to qualitatively and quantitatively assess the driving mechanisms and consequences of marine deoxygenation and CORG burial in a greenhouse world (Fig. 1.5). The focus lies on instances of locally and globally enhanced deoxygenation (Fig. 1.6): the Holocene Baltic Sea (Chapter 2), three sapropels deposited in the

Cephalopod Susceptibility to Asphyxiation via Ocean Incalescence, Deoxygenation, and Acidification [PDF]

Physiology, 2016
Squids are powerful swimmers with high metabolic rates despite constrained oxygen uptake and transport. They have evolved novel physiological strategies for survival in extreme environments that provide insight into their susceptibility to asphyxiation under anthropogenic ocean incalescence (warming), deoxygenation, and acidification.

Sensitivity of fish diel vertical migration depths to future changes in the Pacific Ocean oxygen minimum zone

Frontiers in Marine Science
Diel vertical migrations in the ocean play a key role in predator-prey dynamics and the functioning of the biological carbon pump. However, changes in ocean conditions including warming and deoxygenation threaten to significantly perturb vertical ...

Global evidence of ocean deoxygenation

, 2019
Summary • The global oxygen inventory has decreased by ~2% over the period 1960 to 2010, this finding is supported by regional time series data that indicate a continuous decrease in oceanic dissolved oxygen. • Ocean model simulations predict a decline in the dissolved oxygen inventory of the global ocean of 1 to 7% by the year 2100, caused by a ...

Potential impacts of marine carbon dioxide removal on ocean oxygen

Environmental Research Letters
Global warming is a main cause for current ocean deoxygenation. A deployment of marine carbon dioxide removal (CDR) for mitigating global warming could therefore also be viewed as a measure for mitigating ocean deoxygenation if, and only if, the ...

Recent Declining Trends in Pelagic Fish Catches in the Indian Ocean off Sri Lanka: Is Gill Oxygen Limitation Theory (GOLT) a Possible Explanation?

Asian Fisheries Science
Recent trends in the pelagic fish landings of multi-day fishing fleets operated from Sri Lanka indicated significant declines in many fish species.
