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.

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

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.

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.
