February 9, 2014 | NASA on YouTube.com
“This visualization shows ocean surface currents around the world during the period from June 2005 through Decemeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.” Quoted from the NASA YouTube Channel.
Huge Trench Discovered Beneath Antarctic Ice|
February 2, 2014 | Newcastle University
Researchers have discovered a feature larger than the Grand Canyon beneath the ice of Antarctica. They describe it as: “a massive subglacial valley up to 3 kilometres deep, more than 300 kilometres long and up to 25 kilometres across. In places, the floor of this valley is more than 2000 metres below sea level.” Quoted from the Newcastle University press release.

A Hotspot Under Antarctica?|
December 12, 2013 | Live Science
Researchers have discovered a slow velocity zone under the Marie Byrd Land area of Antarctica, which together with volcanoes above and below the ice suggest the presence of a hotspot.
A Record Temperature of Minus 93C|
December 10, 2013 | BBC
Using satellite thermal sensors, researchers have determined that a record low temperature of approximately minus 93.2C occurred on August 10, 2010 at a location in the center of Antarctica.
IceCube Researchers Detect 28 Neutrinos
November 27, 2013 | National Science Foundation
“Researchers with the IceCube Collaboration have [...] observed 28 very high-energy neutrinos that constitute the first solid evidence for astrophysical neutrinos from cosmic accelerators. [...] IceCube is an [...] astrophysical telescope deployed deep in the Antarctic ice (from 1.4 to 2.4 km depth), but looks over the entire universe, detecting neutrinos coming through the Earth from the Northern skies, as well as from around the Southern skies,” Quoted from the National Science Foundation press release.
A Rumbling Volcano Beneath Antarctic Ice?|
November 18, 2013 | Washington University
“My first thought was, ‘OK, maybe it’s just coincidence.’ But then I looked more closely and realized that the mountains were actually volcanoes and there was an age progression to the range. The volcanoes closest to the seismic events were the youngest ones.” Quoted from the Washington University press release.
M7.8 Earthquake in the Scotia Sea
November 17, 2013 | USGS
“The November 17, 2013 earthquake in the Scotia Sea, to the northwest of the South Orkney Islands, occurred as the result of either left-lateral strike slip faulting on an east-west oriented plane, or right-lateral faulting on a north-south plane. [...] The November 17 earthquake is the latest in a series of moderate-to-large earthquakes to strike the same region over the past several days.” Quoted from the USGS earthquake summary. No tsunami advisories were issued.

September 24, 2013 | Penn State
“Warm ocean water, not warm air, is melting the Pine Island Glacier’s floating ice shelf in Antarctica and may be the culprit for increased melting of other ice shelves.”
Revelations of an Antarctic Ice Core|
September 17, 2013 | National Science Foundation
“Analysis of an ice core [...] reveals that warming in Antarctica began about 22,000 years ago, a few thousand years earlier than suggested by previous records. This timing shows that West Antarctica did not “wait for a cue” from the Northern Hemisphere to start warming, as scientists had previously supposed.” Quoted from the National Science Foundation press release.
Huge Crater in Antarctic Ice|
September 16, 2013 | European Space Agency
“ESA’s CryoSat satellite has found a vast crater in Antarctica’s icy surface. Scientists believe the crater was left behind when a lake lying under about 3 km of ice suddenly drained.” Quoted from the ESA press release.
Life Found in an Antarctic Subglacial Lake|
September 11, 2013 | British Antarctic Survey
“What was surprising was the high biomass and diversity we found. This is the first time microbes have been identified living in the sediments of a subglacial Antarctic lake and indicates that life can exist and potentially thrive in environments we would consider too extreme.” Quoted from the British Antarctic Survey press release.

Ancient Warming of Antarctica|
July 26, 2013 | Imperial College London
“Researchers [...] studied mud samples to learn about ancient melting of the East Antarctic ice sheet. They discovered that melting took place repeatedly between five and three million years ago, [...] during which may have caused sea levels to rise approximately ten metres.” Quoted from the Imperial College London press release.
