The Dead Sea Location/Formation • Located between Jordan, The West Bank, and Israel. • Just outside of the traditional tropics, between 30.5 and 31.5 degrees north latitude • The Dead Sea Transform • The DST is located between the African and Arabian tectonic plates. Weather and Climate • • • • • • Hot and dry climate Average rainfall: 47 mm Average precipitation days: 15 Average summer temperature: 27 – 40 oC Average winter temperature: 11 – 21 oC Average yearly temperature: 22 – 30 oC Sources of Inflow Inflow: • Ground water • Rain water • Surface water – – – – – – – – – – – Jordan River, Zerqa, Mujib, Karak, Hasa, Araba, Harod, Quilt, Malih, Mishash, Arugot, Morphometric Data • • • • • • • • Max length Max width Surface area Average depth Max depth Water volume Shore length Density = = = = = = = = = 67 km 18 km 810 km2 118 m 377 m 147 km3 135 km 1.24 kg/L Salinity • 33.7% salinity • 8.6 times saltier than the oceans • There is roughly 300 grams of salt per kilogram of seawater • There are 35 different types of minerals that make up the salts in the lake Chemical Composition (in G l -1): • • • • • • • • • Mg = 44 Ca = 17.2 Na = 40.1 K = 7.7 Cl = 224.9 Br = 5.3 SO4 = 0.45 HCO3 = 0.1 Total Dissolved Salts = 339.6 • Density = 1.232 Layered in the Lake More Stratification Life in and around the Dead Sea Recorded to have been seen near the Dead Sea Lake: • • • • • • • • Camels Ibex Hares Hyraxes Jackals Foxes Leopards Birds • 152 species of plankton and periphyton were identified in the Jordan River (Tavassi 2008). • Cyanoprokaryota – – – – – – – – Bacillariophyceae Chlorophyta Chrysophyta Cryptophyta Dinophyta Euglenophyta Rhodophyta Xanthophyta Evaporation Ponds • The evaporation ponds in the southern portion of the dead sea are responsible for the production of Sodium Chloride and Potassium salts. In recent years there has been an increase in the demand of these chemicals for the production of polyvinyl chloride (PVC). • Average depth of the these ponds are 4 meters. • http://upload.wikimedia.org/wikipedia/commons/4/4a/Dead_se a_ecological_disaster_1960_-_2007.gif Red Sea – Dead Sea Canal • 1855 William Allen wanted to create a series of canals to channel water from the Mediterranean Sea to the Red Sea. New and Improved Peace Conduit • Implication for: – Freshwater – Hydropower – Sea Level – Aquatic microorganisms – Chemical Composition – Precipitation of salts • Where do things stand now… Pending review.
