Actually OTEC does transfer water from a great depth up to a the surface. This is the cooling water you need for the system to work. This water contains a higher level of carbondioxide than the surface water would contain and you can get some release into the atmosphere. However, I understand this to be considerably less than by burning fossil fuels, something like 5% in comparison. We have a paper covering this at the OTEC Library called Carbon dioxide release from OTEC cycles.
