There is a hidden mysterious world hidden away under Antarctica and researchers have revealed the giant wetlands that are 800 meters beneath the ice.

The Whillans Ice Stream Subglacial Access Research Drilling, or WISSARD for short, a project that was financed by National Science Foundation, has taken researchers that step nearer to discovering just what lies underneath the ice that covers the majority of Antarctica.

Lake Whillans Is Under 800 Meters Of Ice In Western Antarctica

Reports have indicated that Lake Whillans, which was first located in 2007 and which covers more than 20 square miles, is under the 800 meters of ice that is found in Western Antarctica and researchers have said that this is very similar to the wetland.

The researchers are hoping that more studies will mean they can understand better how the level of the sea rises and how the ice is behaving in response to the global warming.

Researchers Are Excited About Rich Dataset Of Lakes

Helen Amanda Fricker from Scripps Institute said that it was amazing to think that people did not know that the lake was in existence until just a decade ago. It was Fricker that had first found sub-glacial Lake Whillans from satellite data back in 2007. She went on to say that it was exciting to be able to see the lakes rich dataset and that the new data is helping them to understand the function of the lakes as a part of the ice-sheet system.

The sub-glacial Lake is fed by ice which has a small amount of seawater in it from the ancient marine sediments that are on the lakes seabed. The lake's water drains periodically into the ocean through channels that are connected to the lake, but they do not have energy enough to carry much of the sediment.

New Data Will Lead To Better Understanding Of Mechanics Of Lake Whillans

Researchers have said that the new data should give them a much better understanding of the mechanics and biogeochemistry of Lake Whillans. It was also said that the data is going to help them to improve the current models and tell them more about how the sub-glacial lake systems in Antarctica interact with any ice that is underneath the surface along with the sediments that are found under it.

In January 2013 three different papers analyzed the studies following the WISSARD project having managed to drill successfully down into the sheet of ice to reach subglacial Lake Whillans, to get some samples of sediment along with water samples that had been isolated from any direct contact with the atmosphere of the Earth for many thousands of years.

The Geology and Earth and Planetary Science Letters journal published two of the more interesting of the papers. Alexander Michaud from the Montana State University and the lead author said that data had come from the 15-inch long core lake sediment so that the water chemistry along with the sediment could be characterized.

Lake Water Mostly Comes From Melting Ice At Base Covering Lake

Researchers found that the water in the lake originates mostly from the melting ice at the base of the sheet that covers the sub-glacial lake and that there had been very little contribution from any seawater, trapped under the ice in the sediment during the last inter-glacial period.

A second paper had been published by lead author Timothy Hodson from the Northern Illinois University in which he along with colleagues took a look at the core sediment that had been retrieved from the lake with the hope of trying to find out more about the ice sheet and the relationship with the sediments under it and the subglacial hydrology. Their discovery found that many floods had passed through the lake but that the floods flow was lacking in energy when it came to eroding the extensive drainage channels.

The researchers came to the conclusion that the environment underneath Antarctica is similar to that of wetlands in the coastal plain that is found in other parts on the planet. Antarctica of course, broke away from Gondwana around 25 million years ago; around 170 million years ago it had been part of the Gondwana supercontinent before breaking away.

Research shows that Antarctica has not always been the very dry and cold region that we know to be covered in sheets of ice. Throughout its long history, it was further to the north and this meant that it experienced a climate that was either tropical or temperate, which would have meant that it had been covered in forest, along with being home to many ancient life forms.
