The Australian summer monsoon is strongly influenced by the Asian winter monsoon, the intensity of which is controlled by changes in solar radiation caused by variations in the Earth's orbit around the sun (Milankovitch effect). This award supports research designed 10 to develop an improved geochronology of lake full events as a first order test of the proposition that January insolation over the Tibetan Plateau can be as a proxy for the intensity of the Australian monsoon; 2) to produce an independent reconstruction of aridity for the last 150 ka across the basin, and reconstruct vegetation during the last lake full interval (60 70 ka), using the isotopic composition of organic and inorganic molecules preserved in ratite eggshells C (reflecting the proportion of C 3 and C 4 plants), and 3) to test the potential impact of vegetation change on climate by modeling the penetration of monsoonal precipitation into the Lake Eyre Basin C T with a high resolution (3 o grid) Global Circulation Model incorporating two different vegetation regimes.
