Deep Antarctic ocean currents have slowed in the past three decades The slowdown in Antarctic circulation reduces oxygen levels across the world’s deep seas. Photo: Tom Williams. Researchers have found that the deep ocean circulation around parts of Antarctica has slowed by 30 per cent since the 1990s, reducing oxygen levels across the world’s deep […]

New ocean model goes in for the krill For the first time, researchers are now able to predict where Antarctic krill populations live and in what numbers—information that is critical to forecasting the future of Southern Ocean ecosystems. The study published this week outlines a new tool, KRILLPODYM, which sheds light on the mysterious lives of these

Seals uncover new ocean depths in East Antarctica Elephant seals fitted with tracking devices. Credit: Clive McMahon, IMOS and SIMS. New ocean depths and seascapes beneath the East Antarctic continental shelf have been revealed in the latest study tracking deep-diving seals, along with detailed information about the waterways that erode the ice shelves from below.

On the edge: warming waters destabilising ‘cold’ ice shelf Researchers have found large-scale anomalies in wind and sea ice are causing the waters below an East Antarctic ice shelf to warm, which could affect future sea level rise across the world. Dr Matthis Auger is a co-author of the new study published in Nature Geoscience, led by

Travel award takes Antarctic studies to Europe Earlier this year, ACEAS PhD student Josef Bisits received the Michael Tallis PhD research travel award, which allowed him to attend a prestigious summer school and an international conference in July for his area of research: physical oceanography.  “Being from Australia it can be difficult to cultivate working

40,000 years of sea ice dynamics unearths future clues A team of researchers has found that a decline in sea ice cover off East Antarctica at the end of the last ice age led to major climate warming and caused the Southern Ocean’s ´control valve´ to open and release carbon dioxide (CO2) into the atmosphere.

Climate drivers are behind Antarctic melt that caused recent sea level rise A team of researchers has revealed that climate variability—specifically the El Niño Southern Oscillation (ENSO) and the Southern Annular Mode—played a significant role in the changes observed in the Antarctic Ice Sheet over the past 20 years. Professor Matt King, Director of the

Past patterns of ice sheet melt reveal worrying clues for future sea level rise Researchers studying the climate of the Last Interglacial have discovered a co-dependent relationship between Antarctic ice sheet melt and ocean warming that reinforces itself. The findings suggest East Antarctica might be even more vulnerable today than scientists previously thought, with a
