As the Dead Sea Dries, Drilling Shows It’s Not the First Time

In the first project of its kind, scientists are drilling deep into the bed of the fast-shrinking Dead Sea, searching for clues to past climate changes and other events that may have affected human history back through Biblical times and before. In one early discovery, they have found that the sea has come and gone in the past—a revelation with powerful implications for the current Mideast.

Spanning Israel and Jordan, the inland Dead Sea is earth’s lowest-lying spot on land, with shores some 1,400 feet below ocean level, and hyper-salty waters going down another 1,200 feet or more. Beneath  lie deep deposits of salts and sediments fed by the Jordan River drainage. The drilling, some 10 years in the making, is being conducted by investigators from Israel, the United States, Germany, Japan, Switzerland and Norway.
