Julie Deshayes and Ruth Curry are highly acknowledged for providing the PAGO diagnostic package (http://www.whoi.edu/science/PO/pago/) (Deshayes et al. 2012, manuscript submitted to J. Climate) used to compute the CM2.1 heat transport components. The HydroBase climatology was kindly provided by Ruth Curry. We thank Steve Griffies, Andrew Wittenberg, Takeshi Doi, and three anonymous reviewers for thoughtful comments that helped improve previous versions of the manuscript.
