How green were our deserts? Evidence for Late Quaternary climate change and the source of water in the Lake Eyre basin

Grant


Scheme


  • Discovery Projects

Abstract


  • This project will reveal when central Australia was significantly wetter than now, if it was warmer or cooler at those times, and whether the runoff in each period came from the tropics or temperate south. It will identify which periods were characterised by sustained wetness and which instead reflect infrequent extreme events, thereby enabling the correlation of the wet-dry cycles with global climate forcing. It will supply reliable data for the retrodictive modelling of moisture and climate change in central Australia, revealing what has influenced the fluctuating supply of water to the agriculturally important eastern Lake Eyre basin.
