A field-scale experiment in the Gulf of Maine involved dissolving sodium hydroxide into coastal waters to enhance CO₂ removal from the atmosphere. The treatment resulted in measurable CO₂ uptake, amounting to several tonnes, and showed no immediate harm to marine ecosystems at the tested site and duration.

Researchers emphasized the need for extended trials and ecological monitoring to evaluate cumulative effects, the permanence of carbon storage, and the technique's feasibility for significant CO₂ concentration reductions globally. This method is viewed as one potential tool in addressing emissions but is not a substitute for comprehensive emissions reduction strategies.
