Southern Ocean Circulation during glacials modeled
« on: September 29, 2015, 05:09:27 AM »
University of Exeter scientists have included the effect of water buoyancy differences of the Ocean water in their model, thus getting their model to behave more like the measurements state. Not surprising at all, the expansion of cold ocean areas around Antarctica let more CO2 to get in there thus a large portion of the glacial-interglacial variations on CO2 levels and temperatures maybe included in some paleoclimate models better than previously.

"During an ice age, the glacial conditions on Antarctica mean that the water near to the continent is colder and so less buoyant. The upwelling of warmer water - during which CO2 is lost to the atmosphere - occurs further away from Antarctica enabling carbon dioxide to be drawn down into the ocean, and also producing a larger volume of deep cold water in the Southern Ocean in which carbon can be stored."
