Five miles out, nearly for the center with the Dead Sea, a worldwide team of scientists continues to be drilling under the seabed to extract accurate documentation of global warming and earthquake history stretching back 500 , 000 years.
The preliminary evidence and clues found halfway with the 40-day project tend to be compared to team may have wished for. The scientists didn't expect you'll pull-up a wood fragment that has been roughly 400,000 yrs . old. Nor did they expect you'll stumbled upon a layer of gravel from the mere 50,000 to 100,000 in years past. That finding would appear to point that what's now the center of the Dead Sea - that is a real big salt lake - used to be a shore, understanding that the lake level had were able to recover naturally.
The concept would have been to bore beneath the sea and extract a continuing geological core that, once analyzed, could supply information of global importance on natural processes and environmental changes.
The Dead Sea sits within the largest and deepest basin on the planet. The scientists thought we would drill at its center simply because they assumed the sediment which had accumulated there had for ages been under water, the higher preserved for having never tried the atmosphere.
The special composition from the Dead Sea waters also affords unique opportunities for research. A particular mineral based in the lake can be utilized for dating much further back in its history compared to the more widespread radiocarbon method allows, giving the scientists an unprecedented comprehension of the of natural forces in the area.
Finally, the International Continental Scientific Drilling Program, which can be located in Germany and it is the sole organization on the planet able to conducting this kind of operation, decided to accept the $2.5 million project like a co-sponsor, with the Israel Academy of Sciences and Humanities.
The Israeli-led enterprise involves 40 scientists from Israel, Germany, Switzerland, Norway, Japan as well as the Usa. Professor Ben-Avraham and his awesome project manager, Michael Lazar, a marine geophysicist in the University of Haifa, emphasized that they are working together with scientists from Jordan and also the Palestinian Authority because Israel, Jordan and also the West Bank all border the Dead Sea.
Using its surface now almost 1,400 feet below sea level and it is waters reaching a depth of a single,240 feet, the Dead Sea provides a unique environment for research that could also bring about the world’s understanding of human cultural evolution.
The very first borehole, completed recently, reached almost 1,500 feet below the seabed before drill head gave out. Experts will log data from this before beginning over a second hole.
The initial hole has produced many plastic tubes full of continuous segments of sediment. They'll be sent for analysis in the University of Bremen in Germany.
Uli Harms, the executive secretary with the international drilling program, said he thought the outlet had penetrated with the sediment from four ice ages. “That will be my own guess,” he explained, adding how the findings must be checked in laboratories.
The project has presented a logistical challenge. The scientists happen to be focusing on the working platform night and day in 12-hour shifts, taken there and back at sunrise and sunset in a boat, the only person around the lake. As a result of high power of salt inside the unusually buoyant water, the vessel needs constant maintenance.
“We are earning history here,” said Gideon Amit, with the National Institute of Oceanography, who's in charge of the marine operations.
Mr. Lazar said the wildly varying layers of salt and mud represented dry periods and wet ones, respectively. A small fragment of wood, which Mr. Lazar said he was guarding like gold, is discovered stuck in certain mud, indicating which it was probably from your tree carried here by way of a flood.
The gravel, just like that found today about the shores from the Sinai Peninsula, may signify the waters within this basin had sunk reduced before than have been previously thought. In light of recent concern on the drop within the Dead Sea’s waters, mainly because of human intervention, the scientists found some room for hope, since the lake had reached even lower levels ever and was able to recover.
There is a momentary hint of one other mystery at dawn on the recent Friday, once the scientists about the drilling platform announced that they just registered a temperature of 104 degrees inside pipes about 1,300 feet down, a finding greater than expected.
The reading gave rise to thoughts of volcanic activity, in the area where Sodom and Gomorrah - the biblical cities described in Genesis as previously being destroyed by God with fire and brimstone because of the residents’ sins - were considered to have stood.
A later reading, however, showed a lesser temperature, inside the range that were anticipated.
