A large air hole of sweet piss that was sucked down into Earth ’s crust 6 million years ago is still bury deeply below a muckle range in Sicily , unexampled research has base .
The bracing water likely became trapped underground during the Messinian saltiness crisis , when the Mediterranean Sea dried up after the ocean floor around the Strait of Gibraltar began to come up , isolating the sea . This event likely exposed the seabed to rain that then filter down into Earth ’s crust , according to a subject publish Nov. 22 in the journalCommunications Earth & Environment .
Sicily is an island off the coast of Italy in the Mediterranean Sea.
The rain accumulated and formed an aquifer that stretched between 2,300 to 8,200 foot ( 700 to 2,500 metre ) deeply beneath the Hyblean Mountains in southern Sicily , Italy , and has not agitate since .
In the new study , researcher investigated abstruse groundwater reserves in and around the Gela establishment , which is a known petroleum man-made lake and host several recondite well , harnessing in public available information from these wells . They constructed 3D fashion model of the aquifer and estimated it holds 4.2 cubic miles ( 17.5 three-dimensional kilometer ) of water — more than doubly as much as is held in Scotland’sLoch Ness .

This diagram shows the newly discovered body of fresh water trapped in the Gela formation beneath Sicily.
The researchers then used the 3D models to work back the clock and rebuild the retiring geology of the study area , which stretch across the Hyblaean Plateau and the Malta Plateau in the central Mediterranean . During the Messinian ( 7.2 million to 5.3 million years ago ) , unused water infiltrated Earth ’s crust several thousand human foot below current sea tier as a result of the salinity crisis , their solution showed . The crisis saw ocean horizontal surface drop about 7,870 feet ( 2,400 m ) below current levels in parts of the Mediterranean .
This " fossil groundwater pool " then roll up in a layer of carbonate rocks that pretend as " a variety of sponge , where fluids are present within the pores between the careen atom , " study lead authorLorenzo Lipparini , a geoscientist at the University of Malta , Roma Tre University and with Italy ’s National Institute of Geophysics and Volcanology , told Live Science in an email .
But for this explanation to moderate , Lipparini and his colleagues postulate to discover a conduit that would channel meteorological water — water from rain and snowfall — from the Mediterranean Davy Jones’s locker to the deeply buried Gela formation . The Malta Escarpment , a190 - mile - long ( 300 kilometers ) submarine cliffextending due south from the easterly margin of Sicily , " is a likely prospect for such a direct connective , " the researchers write in the field of study . In other Word , the missing conduit is likely within the escarp .

The Messinian salinity crisis , which hold up roughly 700,000 years , ended abruptly with an " extremely speedy " climb in ocean levels that may have changed the pressure conditions and " deactivated the whole mechanism , " the researcher wrote in the sketch .
It ’s also possible that sediments and mineral deposits varnish off the conduit along the Malta Escarpment during the saltiness crisis , preventing sea pee from mixing with fresh water in the Gela constitution in the 1000000 of year that followed , the researchers note .
The squad go for the brisk water supply can be pumped up to ease water scarcity in Sicily and that the discovery will inspire similar deep groundwater exploration in other parts of the Mediterranean .
