Records from a variety of archives, such as speleothems and lacustrine deposits, have demonstrated the marked fluctuations in the past climate of the Arabian Peninsula between wet and dry phases.
Such fluctuations would have had a significant effect on Arabian river hydrology, lake levels and ecological community. Spectacular and suitable deposits are present across large tracts of the Arabian Desert, and include long lacustrine and fluvial sedimentary profiles ranging across the Pleistocene and Holocene periods. The record of climate change in the Arabian Desert will also present an opportunity to examine potential continuities and discontinuities in Pleistocene and Holocene settlement and the relative ability of populations to cope with environmental challenges.
