Examples of where such rapid encroachment of the sea occurred include the Persian Gulf and the Gulf of Carpentaria of northern Australia, between about 12,000 and 10,000 years b.p. In some areas of the world the sea-levels peaked at about 6000 years b.p., inundating now low-lying areas before falling slowly to their present position. The consequences of these changes on human settlement and movement have been recognized in the archaeological and pre-historic records. Thus it is widely accepted that levels during 1 otherwise specified.All ages are in conventional radiocarbon years unless the Last Glacial Maximum, about 20,000 to 18,000 years ago, were sufficiently lower than today to leave exposed coastal plains that have since flooded. But less attention appears to have been focused on the timing and rates of change after the onset of melting of the great ice-sheets. What discussion there is -with the exception of the important paper by van Andel & Shackleton (1982) (see also van Andel 1989) -often leaves the distinct impression that this change in level occurred early and quickly with rather minimal human impact. This paper sets out to describe, using the Aegean Sea region as an example, a realistic model of sea-level change and shoreline migration for the past 20,000 years, one that can provide a framework for discussing impacts of :such change on human movements and settlement.If, during the decay of the ice sheets, the meltwater volume is distributed uniformly over the oceans, then the sea-level change at time t would be A&@) = change in ocean volume/ocean surface area (1) This 'eustatic sea-level change' is a function of time. It represents only a zero-order approximation because sea-level does not respond uniformly to the melting of the ice caps: the rates of rise are spatially variable, and in some localities sea-level may actually be falling rela-* Research School of Earth Sciences, Australian National University, Canberra ACT 0200, Australia.Received 2 3 January 1996, accepted 2 6 April 1996.ANTIQUITY 70 (1996):
