"Opportunity for global leadership and lasting legacy" HOBART, Australia, Oct. 20, 2014 /PRNewswire/ -- As representatives of the 25 Members((1)) of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) meet in Hobart, where they will decide the fate of two key protection proposals in the Ross Sea and East Antarctica, the Antarctic Ocean Alliance (AOA) called on the member countries to honour their conservation commitments and finally agree to lasting and...

elusive emperor penguins
2014-06-26 03:11:24

PLOS Field surveys and satellites complement each other when studying remote penguin populations, according to research published June 25 in the open access journal PLOS ONE by André Ancel from the CNRS at Strasbourg and colleagues. Penguins residing on Antarctica's ice sheets must face moving, breaking, and shifting ice. Accurate monitoring of population trends is critical to understanding the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical...

Wilkes Basin in East Antarctica

April Flowers for redOrbit.com - Your Universe Online A new study from the Potsdam Institute for Climate Impact Research (PIK) reveals that a persistent ice discharge into the ocean could be triggered by the melting of just a small volume of ice on East Antarctica's shore. Such a persistent discharge could result in unstoppable sea level rise for thousands of years to come, according to computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the...

East Antarctica Is Pushing Around Its Softer-Mantled Western Half
2013-12-12 07:51:20

April Flowers for redOrbit.com - Your Universe Online It's easy to know what to do when half-siblings are pushing each other around, but what do you do about half-continents? A team of researchers, led by Ohio State University, have discovered that East Antarctica is pushing West Antarctica around. West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East...

West Antarctica's Ice Sheet 20 Million Years Older Than Previosuly Estimated
2013-09-05 07:26:16

April Flowers for redOrbit.com - Your Universe Online A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought. These results, published in Geophysical Research Letters, mark a paradigm shift for our understanding of the Earth’s great global ice sheets. Ice sheets first grew on the West Antarctic subcontinent around 34...

Will Climate Change Make The East Antarctic Ice Sheet More Vulnerable?
2013-08-29 05:41:31

April Flowers for redOrbit.com - Your Universe Online New research from Durham University’s Department of Geography reveals the world’s largest ice sheet could be more vulnerable to the effects of climate change than previously thought. A team of researchers used declassified spy satellite imagery from 1963 to 2012 to create the first long-term record of changes in the terminus of outlet glaciers – where they meet the sea – along 3,355 miles of the East Antarctic Ice Sheet's...

The Forming Of Antarctica's Hidden Fjords
2013-03-06 13:41:41

University of Arizona Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. Although radar surveys have revealed a rugged alpine landscape...

Image 1 - Researchers Unravel Gamburtsev Mountains Enigma

Researchers funded by the National Science Foundation may have finally found how Antarctica´s Gamburtsev Subglacial Mountains were formed, a conundrum that has plagued scientists since they were first discovered in 1958. The international team of scientists explored the subglacial mountain range -- buried under nearly 10,000 feet of ice -- during the International Polar Year (2007-2009) by using two twin-engine aircraft equipped with ice penetrating radar, gravity meters and...

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas. The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past...

Iconic dome at Amundsen-Scott South Pole Station successfully deconstructed; sections may be reassembled at new Navy museum After more than three decades of service to researchers and staff stationed at the bottom of the world, the dome at the Amundsen-Scott South Pole Station was deconstructed this austral summer. The dome provided a platform for countless scientific discoveries in astronomy, physics, climatology, and other fields, and it also provided a home away from home for the station's...
