Random interesting fact

That's about the flow rate of mafic rock required to offset global CO2 emissions, if it went into the ocean mix layer (and dissolved).

Makes you wonder if all those evil villains blowing up volcanoes were really just maligned :).

As fertiliser for algae or in a direct chemical reaction that reacts with the CO2 in the water?

You could think of it as the latter.

It's ocean alkalinity enhancement (offsets ocean acidification, lets the ocean continue to take up CO2).
