-rich Antarctic high-latitude regions for ENSO signatures. Most studies of Pacific extratropical teleconnections to high southern latitudes have focused on West Antarctica, where the extratropical signal is relatively strong and has been linked to variability in surface temperatures, precipitation, sea level pressures, and sea ice extent and thickness (e.g., Cullather et al. 1996 ; Bromwich et al. 2000 ; Kwok and Comiso 2002 ; Meyerson et al. 2002 ; Bertler et al. 2006 ; Yuan and Li 2008 ; Ding et al

decadal variation of detrended global temperature. An update of their graph [Fig. 14 in Timbal and Hendon (2011) ] is shown in Fig. 10 using the Hadley Centre Global Sea Ice and Sea Surface Temperature (HadISST; Rayner et al. 2006 ) to compute the tropical tripole over the period 1865 to 2010. The overall relationship between multidecadal variability in the strength of the coupling between the tropics and SEA rainfall and the detrended global temperature that they noted is also observed in the

Dome, Antarctica, was used by Gergis et al. (2012) to reconstruct rainfall over the southeast Australian region, which approximately includes the lower third of the MDB. In addition to these studies, Vance et al. (2013) used the ice-core record at Law Dome and related summer sea-salt deposition in the ice core with ENSO and rainfall from four stations in eastern Australia, three of which are located in the northern MDB. Although no time series reconstruction was presented, Vance et al. (2013

establish an empirical relationship. Statistical techniques such as linear regression are used to calibrate a proxy variable at a particular location against local or remote climatic variables. Examples include the calibration of coral Sr/Ca and δ 18 O against local sea surface temperature (e.g., Corrège 2006 ) or the calibration of ice core accumulation in Antarctica against precipitation in southwest Western Australia ( van Ommen and Morgan 2010 ). Multiproxy networks comprise data from multiple
