Parameterizing air–sea CO2 transfer in a macroalgal habitat and assessing its role in marine carbon dioxide removal accounting

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Accurately quantifying air–sea CO2 exchange remains a central challenge for the measurement, reporting, and verification (MRV) of marine carbon dioxide removal. I apply direct eddy covariance measurements of CO2 fluxes at a macroalgae‐dominated coast to compile the first gas transfer velocity (k660) parameterization for such a habitat.

Economic Assessment of Ocean Alkalinity Enhancement Through Electrodialysis: The Role of Carbon Credits in Comparing Solar Energy and Thermal Waste Technologies

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
This study evaluates the economic feasibility of an Ocean Alkalinity Enhancement (OAE) plant with an annual CO2 removal capacity of 878 tonnes. The project is profitable only under scenarios with high carbon credit prices, while medium and low‐price scenarios yield a negative net present value.

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 ...

Expert opinions regarding the concept of blue carbon in seaweed systems

Phycological Research, Volume 74, Issue 2, Page 198-208, April 2026.
SUMMARY A collection of expert opinions critically evaluates the role of seaweed in blue carbon strategies for climate change mitigation. While the concept of fast‐growing seaweed to capture atmospheric carbon is appealing, the experts largely agree that its potential for direct, long‐term carbon sequestration is currently overstated and faces ...

Air‐Sea Gas Exchange in the Coastal Baltic Sea: Implications for Marine Carbon Dioxide Removal

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Air‐sea gas exchange affects the biogeochemical cycling of trace gases such as CO2 and dimethyl sulfide (DMS) on a global scale, thereby influencing Earth's climate. In nearshore regions, differences in wind fetch and surfactants are expected to have an impact on gas transfer velocity (k).

A tracer study for the development of in-water monitoring, reporting, and verification (MRV) of ship-based ocean alkalinity enhancement [PDF]

Biogeosciences
Ocean alkalinity enhancement (OAE) is a marine carbon dioxide removal (mCDR) approach that relies on the addition of liquid or solid alkalinity into seawater to take up and neutralize carbon dioxide (CO2) from the atmosphere.

Physical Processes Driving Carbon Subduction in the Southern Ocean in an Eddy‐Permitting Model

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract The Southern Ocean south of 35°S represents a small source of natural inorganic carbon for the atmosphere but a major sink of anthropogenic carbon. The magnitude of the inorganic carbon sink, and the sequestration of inorganic and organic carbon strongly depend on the rate at which they are subducted below the mixed layer.

Emergent seasonal hypoxia and acidification risks induced by seaweed and fish polyculture in the world's largest seaweed farm

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 911-922, December 2025.
Abstract Seaweed farming is increasingly promoted as a carbon sequestration strategy, but its effectiveness relies on carbon burial and export to deep waters. Seaweed farms commonly occupy semi‐enclosed bays, causing continuous accumulation of organic carbon (OC) and its degradation products, potentially undermining carbon sequestration and driving ...

Monitoring marine carbon dioxide removal: quantitative analysis of indicators for carbon removed and environmental side-effects

Environmental Research Letters
Marine carbon dioxide removal (mCDR) implementations can potentially remove 1–15 Gt CO _2 yr ^−1 , which encompasses the minimum requirement removal of CDR in 2050 to limit warming below 2 °C by 2100.

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.
