Swamp-Like Water System Revealed Under Antarctica's Thwaites Glacier
2013-07-09 14:43:50

Lee Rannals for redOrbit.com - Your Universe Online While using an innovative radar analysis method to accurately image the sub-glacial water system under West Antarctica's Thwaites Galcier, scientists discovered a swamp-like canal system beneath the ice. The scientists, from The University of Texas at Austin's Institute for Geophysics, reported in the Proceedings of the National Academy of Sciences (PNAS) that the swamp-like canal is several times as large as Florida's Everglades....

University of British Columbia Detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research by University of British Columbia geoscientists....

After lying dormant underneath a glacier since 2004, a volcano in Iceland began spewing steam, ash and smoke into the upper atmosphere on Sunday. Despite the impressive show, this eruption is less likely to endanger air traffic as a similar eruption last did last year. Closing the main airport in the country as a precaution, pilots were warned to steer clear of Iceland as areas close to the Grimsvotn (GREEMSH-votn) volcano were plunged into darkness. Scientists, however, explain that another...

Study of volcano-ice interaction offers window into geologic past and clues about Earth's long-term climate cycles Glaciovolcanoes, they're called, these rumbling mountains where the orange-red fire of magma meets the frozen blue of glaciers. Iceland's Eyjafjallajökull volcano, which erupted recently, is but one of these volcanoes. Others, such as Katla, Hekla and Askja in Iceland; Edziza in British Columbia, Canada; and Mount Rainier and Mount Redoubt in the U.S., are also...

A rare volcanic eruption is expanding the size of an island in British Overseas Territory. Spectacular new satellite images show that Montagu Island, an erupting volcano in the South Sandwich Islands, South Atlantic has grown by 50 acres (0.2 km2), equivalent to 40 football pitches in the last month. Researchers from the British Antarctic Survey (BAS) and the Hawaii Institute of Geophysics and Planetology (HIGP) were alerted to satellite data showing a large and fast flowing lava flow that...

Grímsvötn
2014-04-08 12:39:42

Grímsvötn is an active subglacial volcano that is located in southeast highlands of Iceland. This volcano reaches an elevation of 5,659 feet and is located in the northwestern side of the Vatnajökull ice-cap. It is comprised of basaltic lava and has the highest frequency of eruptions of any volcano in Iceland. The majority of this volcano resides under Vatnajökull, so its eruptions are primarily subglacial and often cause phreatomagmatic explosions. Grímsvötn produced an eruption in...

Katla Volcano
2014-04-08 11:22:12

Katla Volcano, also known simply as Katla, is an active subglacial volcano that is located in southern Iceland. It reaches an elevation of 4,961 feet and encompasses an area of 230 square miles, making it one of the largest volcanoes in Iceland. Its caldera reaches a diameter of six miles and it is occasionally somewhat covered by the Mýrdalsjökull glacier. The volcano was named for its kettle like shape and its name is often given as a female first name. Katla is thought to have...
