Figure 3. Variations of the sediment residence time in the Murrumbidgee catchment as a function of the deposition age, are compared to (a) Vostok atmospheric carbon dioxide concentration (in ppmv; Petit et al., 1999), (b) estimates of sea surface temperature from planktonic foraminifera (in ºC) (Barrows et al., 2007) and (c) percentage of trees and shrubs in pollen data (Barrows et al., 2007; Heusser and Van de Geer, 1994). (d) Bankfull river discharge of the Murrumbidgee paleochannels as a ratio of the modern river discharge (Page and Nanson, 1996).
