Washington, Jul 12: A team of researchers have discovered a massive landscape lying deep underneath the sediment of North Atlantic Ocean near South coast of Scotland.
The landscape is said to have furrows made by rivers and peaks which once had belonged to mountains.
Geologists believe that the landscape is around 56 million years old.
Senior researcher Nicky White from the Cambridge University, Britain said that it looks like a topography fossil preserved 2 kilometers beneath seabed.
Geologists’ data so far have revealed that the landscape is 10,000 square kilometers west of Orkney-Shetland Islands.
They suspect that it must have been a part of a larger region that may have stretched toward Norway in a hot pre-human day.
Researchers, in their journal Nature Geoscience said that they produced sound waves that travel to the ocean floor and beneath it through layers of sediment using high pressured air via metal cylinders. The sound waves that bounced back as an echo were recorded by microphones trailing behind the ship.
White said that they constructed 3D images of the sedimentary rock below using the information collected.
The team found a wrinkly layer 2km beneath the seafloor as evidence of the buried landscape , reminiscent of the mythical , lost Greek island Atlantis.
Eight major rivers and core samples traced from the rock beneath the ocean floor, revealed pollen and coal, evidence of land-dwelling life.
Evidence of a marine environment above and below these deposits indicates that the land rose above the sea and then subsided.
White’s theory on this mysterious topography states that a giant ripple may have pushed the landscape above the North Atlantic initially and as the ripple passes, the land must have fallen back beneath the ocean.
