Simulated decadal means of Weddell Gyre strengths by 16 IPCC AR4 coupled climate models during the 20th century (IPCC, 2007<ref name="IPCC, 2007">IPCC 2007. Climate Change 2007: The Physical Science Basis. Contribution of the Intergovernmental Panel on Climate Change. Cambridge University Press, Cambridge.</ref>). The Weddell Gyre strength is defined as the absolute transport of the southern limb across the Prime Meridian, whose observed value is 56 , 8 Sv (Klatt et al., 2005<ref name="Klatt et al, 2005">Klatt, O., Fahrbach, E., Hoppema, M. and Rohardt, G. 2005.
