Many efforts have been made to illuminate the nature of past hydroclimates in semi-arid and arid regions, where current and future shifts in water availability have enormous consequences on human subsistence. Deep desert aquifers, where groundwater is stored for prolonged periods, might serve as a direct record of major paleo-recharge events. To date, groundwater-based paleoclimate reconstructions have mainly focused on a relatively narrow timescale (up to ∼40 kyr), limited by the relatively short half-life of the widely used radiocarbon (5.

The Dead Sea (DS) potash industry halite waste accumulation rate is estimated at 0.2 m year, across 140 km of evaporation ponds in Israel and Jordan, totaling ∼28 million m year. As accommodation in the southern DS basin space is nearly exhausted, it is planned in Israel to dredge newly precipitated salt and convey it in a solid state to the northern DS basin by constructing a 30 km conveyor to the northern DS basin where the salt will be disposed.
