TEL AVIV: The Geological Institute of Israel uncovered a by no means earlier than recognized about underwater canyon close to Cyprus. The canyon, referred to as Eratosthenes for the underwater mountain it’s close to, dates again to the Messinian Occasion that transpired about 5.5 million years in the past.
The canyon is about 10 km extensive and 500 m deep and was buried at the start of the Messinian interval earlier than the deposition of the salt layer.It was created when the extent of the Mediterranean Sea decreased on the identical time there was an increase within the salinity of the water, which apparently created gravity currents or dense options that precipitated the destabilization of the submarine slopes and subsidence of the seabed.
The Institute stated that in a broader side this work reveals the environmental circumstances of excessive salinity and decrease sea degree within the deep Mediterranean basin at the start of the Messinian occasion.
Often known as the Messinian salinity disaster, the Messinian occasion was a geological occasion throughout which the Mediterranean Sea went right into a cycle of partial or practically full desiccation.
