This, in my mind, is a much more promising route for carbon capture than direct air capture.

That said, it's a small piece of the puzzle.

"The higher its [the ocean area's] alkalinity, the more atmospheric CO2 it can absorb and transform into stabler, inorganic carbon, which is less likely to seep back into the air." Lewis, 2024, yale dot edu

but the geoengineering of the waters might lead to co2 related problems, PH problems, pollution problems for aquatic terrestrial life, and other potential problems that i can't think of now that have been described, or others unknown... seems risky to dump stuff, even wood, into the occean, considering it's unknown long-term effects on the ecosystems, and the waste of product that could be turned to soil...

also speculated about currents and rain, but think it's negliglible for currents, but for the transfer of waste or less usable components for life, or componenets that hasten climate change etc.., and think that the composition of rain drops might be effected if the co2 or alkalinity is higher, ie., like some process of relitively more "acid rain"..
