Stability of alkalinity in the land-ocean transition zone: a geochemical CDR perspective for the Elbe River, Germany

Environmental Research Letters
Carbon dioxide removal (CDR) strategies like enhanced weathering and river/ocean alkalinity enhancement have been suggested to increase alkalinity in rivers, coastal areas, and eventually oceans.

Slaking quicklime with seawater for open-ocean alkalinity enhancement: technical feasibility and cost implications

Frontiers in Climate
Scalable carbon dioxide removal (CDR) solutions, such as ocean alkalinity enhancement (OAE), are necessary to mitigate climate change. One OAE approach is open-ocean liming, consisting in distributing hydrated lime (Ca(OH)2) to increase seawater ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, EarlyView.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Compound Hypoxia With Heat or Acidification Stress Induces Synergistic and Additive Effects on Coral Physiology

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Multi‐stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperatures. As global and local environmental change increase compound stress events on coral reefs, distinguishing hypoxia‐driven effects and interactive stressor ...

Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...

Regulation of Ocean Alkalinity Enhancement in Washington State [PDF]

This paper focuses on one commonly-discussed ocean carbon dioxide removal approach, ocean alkalinity enhancement (“OAE”), which involves adding alkaline substances to ocean waters in order to increase their ability to uptake carbon dioxide from the ...
