Arabian Sea stratification and deoxygenation driven by weakening monsoon winds over the Holocene

Communications Earth & Environment
Seasonal stratification in the Arabian Sea, driven by monsoon dynamics, fuels one of the planet’s most productive marine ecosystems while intensifying oxygen minimum zones—an interplay with biogeochemical implications, yet its long-term influence on ...

Loss of fixed nitrogen causes net oxygen gain in a warmer future ocean

Nature Communications, 2019
Ocean anoxic events threaten marine ecosystems, and they are predicted to increase as the climate warms. Using model simulations, Oschlies and colleagues show that in spite of rising temperatures, after transitory deoxygenation, microbial denitrification

Coal Mine Wastewater as a Secondary Resource: Advances in Treatment and Value Recovery Technologies

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Coal mine wastewater, which has historically been considered an environmental problem, is becoming more widely recognized as a secondary resource with substantial value recovery potential. Nevertheless, recent progress demonstrates that this wastewater could be converted into highly useful, industrially available pigments (like iron oxides) by

“Young Get Older, But Old Get Younger”: Warming‐Induced Circulation Change Explains Contrasting Pattern of Projected Pacific Deoxygenation

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Future projections of oxygen and water mass age change in the upper Pacific Ocean show a consistent pattern: strong deoxygenation and increased age in the well‐ventilated subtropical gyres, contrasted by weak deoxygenation and younger age in the poorly ventilated tropical oxygen minimum zones.

Research Priorities for Robust Climate Assessments in the United States

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Scientific assessments play a critical role in synthesizing evidence to support evidence‐based decision‐making in many sectors and topics. For climate change, large‐scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from ...

Global ocean gridded dataset and hypoxic zone expansion: reconstructed dissolved oxygen (1960–2021) based on machine learning technique

International Journal of Digital Earth
Due to global warming and the excessive input of nutrients resulting from human activities, ocean deoxygenation is gradually intensifying. However, the sparse spatiotemporal distribution of in situ global dissolved oxygen (DO) observations poses a ...

Role of Salt Fingering in Recovering the Arabian Sea Oxygen Minimum Zone

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Dissolved oxygen (DO) is vital for structuring marine ecosystems and biogeochemistry, making it a sensible indicator of oceanic health. The DO concentration varies spatially, and there are several regional ocean basins characterized by low subsurface oxygen levels.

Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.

Deoxygenation and the impact on ocean biogeochemistry in the Santa Barbara Channel, and the broader implication for deoxygenation policy [PDF]

Deoxygenation occurs along coastal environments and open ocean that affects ocean biogeochemistry and marine species. The causes of deoxygenation are multifaceted and can be influenced by various physical and biogeochemical properties in the ocean.
