The Role of Bubbles in Air‐Sea Gas Exchange: A Critical Review
Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract Air‐sea gas exchange regulates the exchange of climatically important gases between the ocean and the atmosphere, shaping both climate and ocean biogeochemistry. Bubbles beneath the sea surface enhance this exchange by introducing an additional transfer pathway in parallel to the interfacial transfer route.

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.

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 ...

Seeking natural analogs to fast-forward the assessment of marine CO2 removal [PDF]
, 2021 Mitigating global climate change will require gigaton-scale carbon dioxide removal (CDR) as a supplement to rapid emissions reduction. The oceans cover 71% of the Earth surface and have the potential to provide much of the required CDR.

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).
