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.

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. a_ecological_disaster_1960_-_2007.gif 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.
