Meridional heat transport across the Antarctic Circumpolar Current by the Antarctic Bottom Water overturning cell
[1] The heat transported by the lower limb of the Southern Ocean meridional overturning circulation is commonly held to be negligible in comparison with that transported by eddies higher in the water column. We use output from one of the first global high resolution models to have a reasonably reali...
