Any chance to transform that thermal energy to useful forms while you are at it? Arctic OTEC. In the winter that could be some serious Delta T.

There is a third method, a completely passive one. It's used to keep the permafrost from melting under the Alaskan pipeline. There are a huge number of thermal diodes that suck heat out of the permafrost when the air is colder. No moving parts, they contain a radiator on the top and are a closed cylinder with a few gallons of a low boiling liquid inside. It would take an awful lot of them, but a floating version would not be very expensive. They might be even more useful to freeze glaciers to the bedrock on land. If you make a case of the thermal diodes being a test of a geoengineering method, they have been in service since 1977.
