We focus on ACC and Southern Ocean MOC during 1958–2007 in 17 CORE-II forced models.
Most CORE-II simulations are close to eddy saturation.
Most CORE-II simulations are far from showing signs of eddy compensation.
Constant in time or space k results in poor representation of mesoscale eddy effects.
MOC has larger sensitivity than ACC transport even in eddy saturated state.
