Science and Research in Antarctica and the Southern Ocean

Researchers use seismometers to uncover the geology beneath Antarctica's ice

Seismic research by scientists from Washington University in St. Louis resulted in the discovery of a ‘hot zone’ beneath West Antarctica, thought to have a major influence on the flow of ice streams.… Read more »

National Science Foundation research suggests king crabs could move to warmer waters

Researchers at the US National Science Foundation believe that king crab populations returning to the shallow continental shelf could become high-level predators and disrupt the ecosystem there.… Read more »

How Antarctic clouds could help reveal the effects of climate change

Antarctica’s massive ice sheet acts as a global heat sink. As a result, changes in the make-up of Antarctic clouds, such as the amount of ground they cover or how much radiation they absorb, can have ripple effects as far away as the tropics. Climate change researchers need to understand the physics of these clouds if they are to correctly work out how weather around the globe will change as the polar regions warm.… Read more »

CSIRO RV Investigator to study underwater volcanoes in Southern Ocean

A CSIRO Marine National Facility research vessel has departed from Fremantle in Western Australia and headed to the remote subantarctic islands to research the link between active volcanoes on the seafloor and the mobilisation of iron which enriches and supports life in the Southern Ocean.… Read more »

Flying lab to study how the Southern Ocean absorbs carbon

A team of scientists supported by the National Science Foundation (NSF) will be taking off in a specially-modified Gulfstream V jet this month as they survey remote parts of the Southern Ocean.… Read more »

Prof Rob DeConto explains how polar ice sheet movements can help to predict future sea level rise [video]

Rob DeConto, Professor of Geosciences at the University of Massachusetts-Amherst, explains his research on ice sheets in Antarctica and Greenland, and how these can predict future sea level rise.… Read more »

Pine Island Glacier, West Antarctica - the canary in the mine for climate change? [Video]

The Pine Island Glacier, one of the major glaciers draining the West Antarctic Ice Sheet, is rapidly thinning and, at 3mm per decade, is currently the single biggest contributor to sea level rise. The head of the British Antarctic Survey (BAS), Professor Jane Francis, discusses the iSTAR programme undertaken by BAS which seeks to gain a better understanding of the complexities of this relatively fast moving and thinning glacier, as well as the overall stability of the entire Ice Sheet.… Read more »

Prof Tim Naish of the Antarctic Research Centre explains how Antarctica's history is relevant in predicting future sea levels [Video]

Prof Tim Naish, Director of the Antarctic Research Centre at Victoria University of Wellington, explains how the geological record in Antarctica is relevant in predicting future sea-levels.… Read more »

Dr Steve Rintoul on thermal expansion and melting Antarctic ice shelves [video]

Dr Steve Rintoul of the CSIRO explains the part ocean thermal expansion has to play in rising sea levels, the interaction between oceans and ice shelves, and how Antarctic Bottom Water is warming.… Read more »

Type-C Killer whales commute long distances from Antarctica to temperate zones

A team led by Regina Eisert of Gateway Antarctica at New Zealand's Canterbury University, has found that Type-C Killer Whales travel great distances from the Ross Sea to waters north of New Zealand.… Read more »
