You could induce artificial algea blooms. All that needs is iron and light + water soluble co2 and / or o2. If you are greedy you pump light down into the depths , go cubic instead of quadratic?

Intentional oceanic iron fertilization (OIF) is actually well-studied. Unfortunately it carries risks of ecological disruption and can lead to deoxygination (dead zones). Which would long-term hinder our ability to repeat this. It also often leads to methane and nitrous oxide emissions which are both very potent (though shorter lived) greenhouse gasses
