Seeding alkaline particles in the ocean: an effective CO2 removal solution?

Description
From shore to open ocean, introducing finely ground alkaline minerals into the water, a process known as ocean alkalinity enhancement (OAE), can help remove atmospheric carbon dioxide. However, this method is most effective when particles remain suspended in the upper ocean long enough to dissolve. While traditional models assume particles sink slowly at the rate of individual grains, our study reveals that they may sink much faster due to fluid instabilities in dynamic ocean conditions, shortening their dissolution window. This finding underscores the importance of accounting for ocean currents and mixing when designing OAE strategies for carbon dioxide removal.
