GFDL's CM2 Global Coupled Climate Models. Part II: The Baseline Ocean Simulation (2006, background): “High observed value of ACC at Drake Passage is from Cunningham et al. (2003); lower value is from Orsi et al. (1995). Higher value of ACC transport is likely to be more accurate as it includes an (observed) barotropic component.

On the representation of high latitude processes in the ORCA-LIM global coupled sea ice–ocean model (2005, background): “and even exceeds the 10–20% uncertainty that has been suggested by Cunningham et al. (2003). Maximum transport in the Weddell Gyre is 20 Sv and thus substantially lower than observationbased estimates of Fahrbach et al. (1994) and Schr€ oder and Fahrbach (1999).”

GFDL's CM2 Global Coupled Climate Models. Part I: Formulation and Simulation Characteristics (2006, background): “Cunningham et al. (2003) provides an observational estimate of the strength of the ACC as 134 Sv, but there is considerable uncertainty in this number.”
Key features of the IPSL ocean atmosphere model and its sensitivity to atmospheric resolution (2010, background): “16), with a volume transport at Drake passage of 50 Sv, which is much lower than the observational estimate of 136.7 ± 7.8 Sv (Cunningham et al. 2003).”
The dynamical balance, transport and circulation of the Antarctic Circumpolar Current (2004, background): “Various attempts have been made to determine the absolute or net transport by taking reference velocities from moorings or LADCP (Lowered Acoustic Doppler Current Profiler) or by levelling bottom pressure gauges (see the recent discussion of Cunningham et al. 2003).”
The Low-Resolution CCSM4 (2012, background): “Due to this northward shift, the Antarctic Cir-cumpolar Current transport at Drake Passage is only 105 Sv, lower than the Cunningham et al. (2003) observational estimate of 137 6 8 Sv.”
Changes in the ocean transport through Drake Passage during the 1980s and 1990s, forced by changes in the Southern Annular Mode (2004, background): “(Figure 1); consequently logistics are easiest, and complications with possible additional flows from the subpolar or subtropical gyres are avoided [Whitworth, 1983; Whitworth and Peterson, 1985; Meredith et al., 1996; Cunningham et al., 2003].”
