Scientists discover why the Mediterranean Sea dried up 6 million years ago

A study by the French Research Institute CNRS has revealed the cause of the almost total evaporation of the Mediterranean Sea around six million years ago, a phenomenon that turned it into a vast salt lagoon.

About 83% of the Mediterranean's water evaporated, which explains the presence of over a million cubic kilometers of salt deposits on the seabed. Until now, the cause of this complete drying was a mystery, but the new study sheds light on the reasons.

It seems that the Strait of Gibraltar, which connects the Atlantic Ocean with the Mediterranean Sea, has been almost completely closed for about 10,000 years, preventing water from passing through. This has caused the water to evaporate, but the salt has remained on the surface, forming a giant salt marsh.

"The withdrawal of water from the Atlantic Ocean transformed the Mediterranean Sea into a large salt pan (5.97-5.33 million years ago)," the study says.

This happened after the Strait of Gibraltar was closed, possibly due to high tectonic activity.

"During this extreme reduction, the eastern part of the Mediterranean lost up to 83% of its water volume, while some deep areas, such as the Ionian and Herodotus, remained filled with salt water," the study shows.

Finally, around 5.3 million years ago, a great flood is believed to have occurred, returning salty waters to the Mediterranean through the Strait of Gibraltar.
