  1. Dead Sea desiccation LAWRENCE NEMEH 2014

  2. DEAD SEA BASICS • One of the saltiest seas in the world • Lowest elevation of the world, deepest salt lake in the world • Virtually impossible to host life = DEAD • Density, the floating effect • Vital interest for the region

  3. IDENTIFYING DESICCATION • Rapid recession of the Dead Sea’s surface level • Surface level from -395m to -418m between 1970- 2006 • 20m total, or 1m/year

  4. LINKS & CAUSES • Rising populations • Expanding agricultural sectors • Dams • Major industrial activities • Dead Sea Works processing potash from the man made evaporation ponds in the southern part of the sea

  5. IMPACTS • Sinkhole phenomenon • Desiccation, groundwater level recedes, allows freshwater to invade underground layers, displacing brines, dissolving salt layers, creating new cavities until ground surface collapses • Impacts the integrity of the land, commercial interests (hotels, restaurants) and lives

  6. RED SEA-DEAD SEA CANAL • Agreement between Israel, Jordan and the Palestinian Authority • Mission: transporting water north from the Red Sea to the Dead Sea • Desalination facility to purify half the water for Jordanians and Palestinians and for Israel’s use in the Arava and Eilat • Plans began in 2009, aiming for production in 2017

  7. SECOND TIMES THE CHARM? • ~100,000 years ago: Dead Sea almost dried up • Geologists from the Lamont Doherty Earth Observatory at Columbia University • Drilled a core to analyze about 250,000 of sediment history • Discovered 45-meter salt layer within the core
