Upper‐Ocean Variability of the Marine Carbonate System in the Northeast Pacific

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract In the Northeast Pacific, the marine carbonate system's variability across timescales is not well constrained. Here, we quantify observed seasonal and non‐seasonal variability in Dissolved Inorganic Carbon (DIC), partial pressure of carbon dioxide (pCO2 ${\text{pCO}}_{2}$) and aragonite saturation state Ωa $\left({{\Omega }}_{a}\right)$ and ...

Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

A Revised Estimate of Calcium Carbonate Dissolution in Coastal and Shelf Sediments Suggests Large Shelf Exports in the Marine CaCO3 Cycle

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Calcium carbonate (CaCO3) dissolution plays a key role in the marine carbon and alkalinity cycles and the regulation of atmospheric CO2 levels across geological time scales. Until now, most attention has focused on dissolution in the deep sea, while dissolution in coastal and shelf environments remains poorly constrained.

A novel methodology to characterize the potential impacts of electrochemical ocean alkalinity enhancement on juvenile coho salmon (Oncorhynchus kisutch)

Frontiers in Climate
Ocean alkalinity enhancement (OAE) includes a branch of marine carbon dioxide removal (mCDR) methods that add alkalinity to the surface ocean, leveraging the ocean's vast natural ability to capture and store atmospheric CO2.

Impulse response functions as a framework for quantifying ocean-based carbon dioxide removal [PDF]

Biogeosciences
Limiting global warming to 2 °C by the end of the century requires dramatically reducing CO2 emissions, and also implementing carbon dioxide removal (CDR) technologies.

Plankton do not care: Minimal effects of ocean liming on plankton growth and grazing in the Eastern Mediterranean

Limnology and Oceanography, Volume 70, Issue S2, Page S242-S257, December 2025.
Abstract Increasing CO2 emissions have led to the development of CO2 removal strategies to counteract ocean acidification. Among these, ocean alkalinity enhancement techniques, particularly ocean liming, may represent a promising approach to restore seawater pH and boost CO2 sequestration.

A high-resolution nested model to study the effects of alkalinity additions in Halifax Harbour, a mid-latitude coastal fjord [PDF]

Biogeosciences
Surface ocean alkalinity enhancement (OAE), through the release of alkaline materials, is an emerging marine carbon dioxide removal technology that could increase the storage of anthropogenic carbon in the ocean.

Early Career Recommendations for the Equitable Growth of a Marine Carbon Dioxide Removal Sector

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract In addition to steep carbon emission reductions, all modeled pathways to reach global climate goals require carbon removal. Marine carbon dioxide removal has the potential to play a large role in drawing down legacy anthropogenic emissions due to the scalability and durability of proposed methods.

A Review of the Spatiotemporal Evolution of the High Arctic Large Igneous Province, and a New U‐Pb Age of a Mafic Sill Complex on Svalbard

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The High Arctic Large Igneous Province (HALIP) formed in the circum‐Arctic during the Cretaceous. The timing and duration of emplacement of these mafic magmas are important for understanding the climatic and environmental effects, yet many uncertainties remain. The dating methods used vary greatly between different regions.
