Ice shelf vibrations cause unusual waves in Antarctic atmosphere

Low-frequency vibrations of the Ross Ice Shelf are likely causing ripples and undulations in the air above Antarctica, a new study finds. Using mathematical models of the ice shelf, the study's authors show how vibrations ...

Seals help plug Antarctic water mystery

Elephant seals have helped scientists to demonstrate that fresh water from Antarctic's melting ice shelves slows the processes responsible for the formation of deep-water ocean currents that regulate global temperatures.

Study helps explain sea ice differences at Earth's poles

Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern ...

Warming ocean water undercuts Antarctic ice shelves

"Upside-down rivers" of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder's National Snow and Ice Data Center ...

Antarctic ice safety band at risk

Antarctica is surrounded by huge ice shelves. New research, using ice velocity data from satellites such as ESA's heritage Envisat, has revealed that there is a critical point where these shelves act as a safety band, holding ...

The lasting legacy of climate change

An international team led by Dr Nicholas Golledge, who holds a joint position at Victoria University's Antarctic Research Centre and GNS Science, has published a paper in the respected scientific magazine Nature titled 'The ...
