Carbon dioxide removal efficiency of iron and steel slag in seawater via ocean alkalinity enhancement

Frontiers in Climate
Ocean alkalinity enhancement (OAE) via the enhanced weathering of alkaline minerals is a promising carbon dioxide removal (CDR) technology. Theoretically, these includes iron and steel slags, although their dissolution kinetics in seawater are unknown ...

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.

Carbonate System Site Selection Characteristics for Ocean Alkalinity Enhancement in the US Northeast Shelf and Slope

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Ocean alkalinity enhancement (OAE) is a marine carbon dioxide (CO2) removal strategy that relies on lowering the ocean's pCO2 via the addition of alkaline materials to facilitate enhanced CO2 uptake with the potential for durable, long‐term, storage.

Effect of Model Resolution on Air‐Sea CO2 Equilibration Timescales

Global Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract Marine Carbon Dioxide Removal (mCDR) will likely play a role in efforts to keep global warming below 2°C. mCDR methods create a deficit in dissolved seawater CO2 relative to the unperturbed counterfactual. This seawater CO2 deficit induces either an uptake of atmospheric CO2 or reduced CO2 outgassing into the atmosphere. The immediate climatic
