captures much of the carbon and returns it to the biosphere. This is 
important for OTEC schemes that plan to sequester carbon by locking it 
up in algae and sinking it to the ocean bottom. From this study, it 
looks as if the material needs to be deposited at least 1000 meters down 
to get a maximum impact.
