Shore-line reconstruction around Australia during the Last Glacial Maximumand Late Glacial Stage

Being both relatively tectonically stable and far from formerly glaciated r egions, continental Australia is particularly well-suited for the study of sea-level evolution since the Last Glacial Maximum (LGM) and the Late Glaci al Stage. Sea-level data from such regions are valuable indicators of ice-v olume equivalent sea level since the effects of glacio-hydro-isostatic term s is less significant for far-field sites though still not negligible. In t his study, we review published sea-level observations and results of recent ly developed numerical models for several areas of coastal Australia and pr oduce corresponding palaeogeographic maps of the results of our numerical m odels. The results suggest that the Australian continental shelf was largel y exposed during the LGM and provide detailed predictions of the timing of inundation as a function of position. Temporal and spatial variation of sea level provide important constraints that can in turn be used to improve th e accuracy of numerical models, and better determine important rheological response parameters for the mantle and environmental conditions during the Late Glacial. The palaeoshoreline data from the modeling performed in this study indicate several key locations for future palaeo-environmental studie s of sea-level change.
