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. This strategy has gained recent scientific and private sector attention as a possible component of climate mitigation portfolios, yet many research questions remain. This work describes an analysis of historical reconstructions of regional carbonate chemistry developed via application of machine learning algorithms to an ocean reanalysis product.
