Re-aware Global Ocean Deoxygenation During the Past 140 Years

, 2023
The intensifying global ocean deoxygenation has significant impacts on the oceanic ecological equilibrium. Gaps persist in understanding the dynamic evolution of global ocean oxygen throughout the 20th century due to the spatiotemporal sparsity of ...

Trends and decadal oscillations of oxygen and nutrients at 50 to 300 m depth in the equatorial and North Pacific [PDF]

Biogeosciences, 2020
A strong oxygen-deficient layer is located in the upper layers of the tropical Pacific Ocean and deeper in the North Pacific. Processes related to climate change (upper-ocean warming, reduced ventilation) are expected to change ocean oxygen and nutrient ...

Biogeochemical feedbacks may amplify ongoing and future ocean deoxygenation: a case study from the Peruvian oxygen minimum zone

Biogeochemistry, 2022
A new box model is employed to simulate the oxygen-dependent cycling of nutrients in the Peruvian oxygen minimum zone (OMZ). Model results and data for the present state of the OMZ indicate that dissolved iron is the limiting nutrient for primary ...

Ocean deoxygenation: a primer [Elektronisk resurs]

, 2020
Earth’s ocean is losing oxygen; since the mid-20th century, 1%–2% of the global ocean oxygen inventory has been lost, and over 700 coastal sites have reported new or worsening low-oxygen conditions.

Transcriptional responses indicate acclimation to prolonged deoxygenation in the coral Stylophora pistillata

Frontiers in Marine Science, 2022
The current decrease in oceanic dissolved oxygen is a widespread and pressing problem that raises concern as to how marine biota in general, and coral reefs in particular will be affected. However, the molecular response underlying tolerance of corals to

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Microbial responses to ocean deoxygenation

, 2022
The oceans are losing oxygen (O2) as the combined result of rising global temperatures and increasing anthropogenic nutrient inputs. This deoxygenation impacts directly on marine ecology, including increased mortality rate, impaired growth, and altered ...

Is deoxygenation detectable before warming in the thermocline? [PDF]

Biogeosciences, 2020
Anthropogenic greenhouse gas emissions cause ocean warming and oxygen depletion, with adverse impacts on marine organisms and ecosystems. Warming is one of the main indicators of anthropogenic climate change, but, in the thermocline, changes in oxygen ...

The vulnerability of sharks, skates, and rays to ocean deoxygenation: Physiological mechanisms, behavioral responses, and ecological impacts.

Journal of Fish Biology
Levels of dissolved oxygen in open ocean and coastal waters are decreasing (ocean deoxygenation), with poorly understood effects on marine megafauna.

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.
