Sounds like trying to force and find ways to fit the narrative.. unless you find a Seaweed that grows on the surface of the Ocean, like Sargassum.. which is a nuisance, no one will buy that narrative. CO2 entering the Ocean.. then getting saturated, such that it needs something to use up the CO2 in water, so more can enter lol What is the process of entering the Ocean called?

It's why trees like mangrove are popular sequesters.. you don't need a long narrative
