The continuous and partly laminated lacustrine sediments of ICDP Dead Sea Deep Drilling Program Site 5017-1 and lacustrine sediments deposited at the margins of the Dead Sea provide unique archives on past variations of sediment supply by rivers draining the Levant. These sediment records are highly sensitive to past hydrological changes and offer detailed chronological constrains on rapid climatic events in the Dead-Sea watershed. Low-resolution reconstruction of hydrological changes in the Levant over the past ~20ka BP has been obtained form radiogenic isotope signatures (Nd and Sr) of different western tributaries to the ICDP site. Short-term hydroclimatic variability such as local floods possibly constitute a dominant phenomenon during rapid climate changes in the Dead Sea region, such as the 8.2 ka event or the centennial droughts of the Bronze Age. However, the contribution of different tributaries during short-term hydroclimatic variability are still unknown, but can be addressed by investigating detailed and continuous records of both the deep basin and the margins. In this renewal proposal (PRO-HYDRO II), we propose to extend the record provided by the ICDP site 5017-1 and the western Dead Sea margin recovered during the first phase of PRO-HYDRO with unique sediment archives from the eastern (Jordanian) Dead Sea margin. This synoptic reconstruction will provide key insights into the interplay between northern and southern precipitation regimes, at a near-annual resolution.
