Description :
In this study, 2 deep-sea sediment cores, from near the center of the dust path that crosses the Tasman Sea from Australia, were sampled for particle-size analysis of eolian dusts deposited from the Last Glacial Maximum, (LGM), to the Holocene by the Southern Hemisphere zonal westerly winds. From these results it appears that activation of desert dunefields over 40% of Australia during the LGM was the result of a reduction in stabilizing vegetation and more frequent episodes of sand movement rather than of increased wind strength.
