A study of ice and fire
Although the volcanoes cover a wide area, they are "especially concentrated and orientated" in a particular area central to the 2,200-mile-long West Antarctic rift system, a series of rifts in the ice where all of the continent's most recently active volcanoes are located.
If the discovery is validated by further work, the newly-found volcanoes could make the West Antarctic Ice Sheet home to one of the densest volcanic ranges in the world, similar to East Africa's volcanic ridge.
Researchers say the discovery could help them better understand how Antarctica has changed during the varying climates of history, and how volcanoes influence ice sheet fluctuations.
Scientists would have to conduct further research to determine whether those volcanoes are active or not. "Anything that causes the melting of ice - which an eruption certainly would - is likely to speed up the flow of ice into the sea".
Scientists at the University of Edinburgh came to this conclusion after they found 91 volcanoes that had remained hidden from geological surveys. The volcanoes in the region range in height from 100 meters to 3,850 meters tall.
Officer shot by armed suspect ignoring orders in SC James Dunne, an emergency room physician, testified that a bullet completely severed a vein in Smith's neck. I'm hit in my neck someplace, my arms are broken, help me please", he implores as his voice gets weaker.
The dozens of newly determined formations almost double the 47 volcanoes previously located in West Antarctica, with the newly identified volcanoes towering up to 2.4 miles in height.
They used ice-penetrating radar carried by planes and land vehicles to analyse measurements made by previous surveys and survey strips of west Antarctic ice.
Researchers said there is a volcano every 4,800 square miles. "Essentially, we were looking for evidence of volcanic cones sticking up into the ice", Bingham said. Earth science experts have determined that glaciers covered the most active volcano regions in the world, like Alaska and Iceland, during the last ice age.
Dr Bingham's fear is that the Antarctic ocean's meltwater outflows will cause sea levels to rise. They also believe "understanding of volcanic activity could shed light on their impact on Antarctica's ice in the past, present, and future, and on other rift systems around the world".
'We have nearly trebled the number of volcanoes known to exist in west Antarctica.
"It is something we will have to watch closely", Bingham told The Guardian.
NYPD Officer Shot, Bullet Proof Vest Saved His Life
De Blasio said the wounded cop had a "great attitude" as he lay in his hospital bed and even made light of his situation. After the shots were fired, the suspect then barricaded himself in the backyard of the home, armed with his gun.
Snap Inc.'s Slow Second-Quarter Growth Disappoints Wall Street
In Canada and the USA , there were 75 million daily users at the end of last quarter, compared to 71 million in the first quarter. But the firm added just seven million new users in the quarter, compared to eight million in the first three months of the year.
Warm temps, chances of rain for your Sunday afternoon
At the very least, the morning and early afternoon will be partly sunny and pleasant with just a gradual elevation of humidity. Although clouds will be nearly nonexistent, moonlight is still in ample supply and will make seeing the meteors harder to see.
