Researchers have actually found 3 huge canyons in Antarctica

Researchers have actually found 3 huge canyons in Antarctica

The Patuxent Trough is more than 300km long and over 15km broad, while the Offset Rift Basin is 150km long and 30km large.

Winter and her colleagues were particularly interested in an area scientists dubbed the "bottleneck" zone, where the east and west Antarctic ice sheets come together.

They channel it from the South Pole to the coast of West Antarctica where the Ross Sea is located and to the coast of East Antarctica where the Weddell Sea is located.

" These troughs channelise ice from the centre of the continent, taking it to the coast", discussed Dr Winter season. Given the drastic climatic change predicted for the region, there are fears that the troughs will speed up to a great extent ice streaming towards the sea, thereby causing an abrupt rise in sea level.

To reach the bottom of the largest trench, the Foundation Trough, you would need to drill through 1.2 miles (two kilometres) of solid ice.

The Allan Hills fall within a region called the Transantarctic Mountains, whose steep, uneven topography was long thought to be too unstable to contain deep, ancient ice of this kind. They could, therefore, predict how these ice sheets will react in response to climate change at present.

Ice cores, long vertical samples taken from glaciers and ice sheets, can tell us a lot about the past - details in each individual layer of the sample contains clues about the age when it was formed, and big enough samples can go way back in time.

While Klopp failed to win his 2013 final against German side Bayern Munich when he was managing Borussia Dortmund. Meanwhile, Ronaldo could win his fifth Champions League, a landmark reached by only four players before now.

" Individuals had actually called this location a traffic jam", stated team-member Dr Tom Jordan from the British Antarctic Study (BACHELOR'S DEGREE).

As the BBC points out, this paper is the first to come out of PolarGAP, a project of the European Space Agency to take observations of a part of the planet that its satellites can not "see", because they don't orbit over the planet that far south.

Researchers studying Antarctica haven't come up with good news for a while, and it seems that this is the place where they discover the most worrisome things about our planet. The PolarGAP project is flying radar-equipped planes over those places to collect data in the satellites' stead.

The insights for Dr Winter season's paper originated from an air-borne ice-penetrating radar. It will likewise map the shape of the basement rock.

According to Dr Fausto Ferraccioli, this has resulted in the South Pole region remaining "one of the least understood frontiers in the whole of Antarctica". With this major discovery, the researchers expect to obtain near about two hundred thousand more years' old information as compared to the previous ice bed data that was near about eight hundred thousand years old.

"Our new aerogeophysical data will... enable new research into the geological processes that created the mountains and basins before the Antarctic ice sheet itself was born".
