Lost City Of Atlantis. [Not So Lost Anymore]

Scientists believe they may have found the lost city of Atlantis 1.2 miles below the arctic sea. 

Geologists have discovered an ancient underwater landscape more than a mile beneath the surface of the North Atlantic Ocean. The 56-million-year-old landscape, which was uncovered by a team of researchers from the University of Cambridge, UK, whose findings appear in the July 10 issue ofscientific journal Nature Geoscience, reveals evidence of human inhabitants.

The team, led by Cambridge graduate student Ross Hartley, used images created using an echo-sounding technique that bounces sound waves off the sea floor to develop a map of the landscape. The data was collected by a seismic contracting company that gathers information for oil companies, reports FoxNews.com.

The 3,861 square miles of newly discovered landscape is located just west of the Shetland Islands, which are located in the  between northern Scotland and Norway, at the convergence of theNorwegian Sea and the North Sea.

The research team has so far found a total of eight major rivers in the covered landscape. And rock samples taken from the sea floor show evidence of pollen and coal, which suggests humans once inhabited the land. Harley and his team predict that the sunken land mass once connected Scotland to Norway.

What remains one of the primary mysteries of this discovery is why the landscape, which geologic evidence shows was once above sea level, now resides about 1.2 miles under water.

Their answer so far is that the Icelandic Plume, which carries magma from deep within the Earth’s mantle, emitted a “giant hot ripple” of molten rock, which pushed the lost land up above the water. Eventually, the ripple passed, and the land receded back to its water depths.

Sedimentary basins in the North Atlantic Ocean preserve a record of intermittent uplift during Cenozoic times1. These variations in elevation are thought to result from temperature changes within the underlying Icelandic mantle plume2. When parts of the European continental shelf were episodically lifted above sea level, new landscapes were carved by erosion, but these landscapes then subsided and were buried beneath marine sediments3. Here, we use three-dimensional seismic data to reconstruct one of these ancient landscapes that formed off the northwest coast of Europe during the Palaeocene–Eocene Thermal Maximum. We identify a drainage network within the landscape and, by modelling the profiles of individual rivers within this network, we reconstruct the history of surface uplift. We show that the landscape was lifted above sea level in a series of three discrete steps of 200–400 m each. After about 1 million years of subaerial exposure, this landscape was reburied. We use the magnitude and duration of uplift to constrain the temperature and velocity of a mantle-plume anomaly that drove landscape formation. We conclude that pulses of hot, chemically depleted, mantle material spread out radially beneath the lithospheric plate at velocities of ~35 cm yr−1.

    The article contains a significant error. The team did not find evidence of human habitation. There were no humans on Earth 56 million years ago. The site is interesting but has nothing to do with Atlantis which was much further south, being a supervolcanic island off Portugal that exploded and sank in the 17th century BC (see Roots of Cataclysm, Algora Publ. NY 2009).
