“…The advent of optically stimulated luminescence (OSL) dating (see review in Singhvi and Porat, 2008) has revolutionized paleoclimatic studies of dunes, as the only requirement is the presence of quartz, which is rarely an issue with aeolian sand. Recent studies of the dunefields in the Sahara, the SinaieNegev erg, and the Arabian Peninsula, with good OSL geochronology, have yielded important paleoclimatic information in Mauritania (Lancaster et al, 2002), Egypt and Sudan (Bubenzer et al, 2007), Israel (Roskin et al, 2011a(Roskin et al, , 2011b and Arabia (Goudie et al, 2000;Preusser et al, 2002Preusser et al, , 2005Atkinson et al, 2011Atkinson et al, , 2012, as well as regional syntheses (Swezy, 2001;Glennie and Singhvi, 2002;Lancaster, 2007Lancaster, , 2008Singhvi and Porat, 2008). One conclusion common to these studies is that dunes over a wide region were very active during the Last Glacial Maximum (LGM), but dune activity diminished at the close of the Last Glacial period, a concept articulated earlier by Sarnthein (1978).…”
