A string of a dozen volcanoes, at least several of them active, has been found beneath the frigid seas near Antarctica, the first such discovery in that region.
Some of the peaks tower nearly 10,000 feet (3,000 meters) above the ocean floor — nearly tall enough to break the water's surface.
"That's a big volcano. That's a very big volcano. If that was on land it would be quite remarkable," said Philip Leat, a vulcanologist with the British Antarctic Survey who led a seafloor mapping expedition to the region in 2007 and 2010.
The group of 12 underwater mountains lies south of the South Sandwich Islands — desolate, ice-covered volcanoes that rise above the southern Atlantic Ocean about halfway between South America and South Africa and erupted as recently as 2008. It's the first time such a large number of undersea volcanoes has been found together in the Antarctic region.
Leat said the survey team was somewhat surprised by the find.
"We knew there were other volcanoes in the area, but we didn't go trying to find volcanoes," Leat told OurAmazingPlanet. "We just went because there was a big blank area on the map and we had no idea what was there; we just wanted to fill in the seafloor."
IT SURE AIN'T THE CO2.
IOW: AGW = TFBS.
