Is the world's largest canyon hidden under an Antarctic ice sheet?

Christian Science Monitor: Scientists say they may have discovered the worlds largest canyon, concealed under a vast Antarctic ice sheet. A team of researchers led by Britains Durham University made the discovery using satellite data, which has shown hints of the canyon. Smaller sections of the chasm were also identified using radio-echo sounding technology, which sent radio waves through the ice to map the canyons shape in a remote section of the British Antarctic territory, the university said. When combined, the...

Antarctic scientists head to biological hotspot studying climate change in Southern Ocean

Australian Broadcasting Corporation: For the first time since Sir Douglas Mawson's Antarctic expeditions in the 1920s and 1930s, scientists will be conducting climate studies in the area known as the Kerguelen Plateau, in the Southern Ocean. The Kerguelen Plateau, hundreds of kilometres north of Mawson Station, is one of only three lines of longitude where the Antarctic Circumpolar Current flows across the Antarctic continental shelf, the deep ocean and subantarctic islands. That makes it one of the most highly productive regions...

West Antarctic coastal snow accumulation rose 30% during 20th century
2015-11-04 11:29:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: Annual snow accumulation on West Antarctica's coastal ice sheet increased dramatically during the 20th century, according to a new study published in the American Geophysical Union journal Geophysical Research Letters. The research gives scientists new insight into Antarctica's blanket of ice. Understanding how the ice sheet grows and shrinks over time enhances scientists' understanding of the processes that impact global sea levels, according to the study's authors. The new study used ice...
Experts dispute NASA study showing Antarctic ice gain
2015-11-03 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Al Jazeera: A number of experts are disputing the conclusion of a recent NASA study that says more ice is accumulating in Antarctica than is being lost due to climate change. They argue that the study contradicts more than a decade of other scientific measurements -- including previous NASA studies. The NASA report issued last week, Mass Gains of Antarctic Ice Sheet Greater than Losses, argued that snow accumulation in East Antarctica has added enough ice to the continent to outweigh the losses from the...
Antarctic Ice Sheet Is Reportedly Gaining More Mass Than Is Losing
2015-10-31 22:27:00| Climate Ark Climate Change & Global Warming Newsfeed
Inquisitr: The Antarctic ice sheet is gaining more mass than it is losing, according to recent studies conducted by NASA. Researchers admit some glaciers are indeed thinning. However, snow accumulation continues to offset the loss by increasing the mass of the continent`s overall land ice. As explained by the National Snow & Ice Data Center, ice sheets, which are also referred to as glacial land ice, are solid masses of ice covering a mass of land. They are specifically defined by their size, which must...
