Analysis of the sediment from the bottom of the Dead Sea has shown that about 120 thousand years ago, the pond is completely dry.
Lake and is now under threat of extinction due to global warming. Over the past decade, the water level fell markedly.
As part of the project "Deep drilling from the Dead Sea," $ 2.6 million in the period from November 2010 to March 2011 was received a few samples of bottom sediments. Scientists are interested in the history of climate and earthquakes in the region.
They found a layer of round pebbles at a depth of 230 m below the seabed. It is an ancient gravel beach, which existed when the lake dried up completely or almost completely.
Previous experiments with water from the Dead Sea shows that the lake could disappear all because the loss of water would lead to an increase in the concentration of salt and would prevent further evaporation. But the new findings call this assumption into question. This means that as the region will become warmer and drier, the Dead Sea will order to live long, said team leader Amy Ito of the University of Minnesota (USA).
The lake level is rapidly decreasing due to removal of Israel and Jordan, the water from the rivers flowing into the Dead Sea. For 14 years, he fell 14 meters and today at 425 meters below sea level. Currently, Israel and Jordan consider project completion lake due to the channel of the Red Sea.
Results of the study were presented at the meeting of the American Geophysical Union.
