I don't recall freezing or sub freezing temperatures near the sea floor anywhere we dropped our thermography zingies. I believe it was more like say 2 to 5 degrees C.

That's the reason those waters are very cold, at of below freezing. There are two regions at which the THC is found, around the Antarctic and in the high latitude North Atlantic, the Arctic Ocean and the Nordic seas. The sinking is associated with the growth of sea-ice, a process which results in the release of high salt content brine, which, when added to the surrounding water, makes that water dense enough to sink to the bottom. The rate of the sinking varies with season and on longer time scales. The sinking water also transports CO2 into the deepest layers of the oceans.<br /><br />Eli's discussion doesn't directly mention the THC process, which is expected to weaken in the Northern Hemisphere due to AGW. That's due to freshening of the surface layer at high latitudes, due to increased moisture transport from lower latitudes, more water from the glaciers of Greenland, and the export of low salinity water and sea-ice from the Arctic Ocean. <br /><br />As the THC weakens, the net effect may be a reduction in the rate of CO2 sequestration in the deep oceans as upwelling processes could be expected to continue bringing deep waters toward the surface, releasing CO2 as those cold waters warm up.E.
