Ocean seeding may not work at all. The nutrients available are already just right, and adding more will only increase local growth at the expense of sucking up nutrients that would have spread elsewhere. Total sunk co2 wouldn't increase, and may even decrease.

There's a lot of unknowns with kelp farming. It may not sequester co2 for long enough. Needs more research.

What would work is a tank of algae, where we then siphon them off and throw them down a mineshaft. That's too expensive right now, though.
