Such decline of this ocean circulation will stagnate the bottom of the […]

Southern Ocean holds deep clues to ancient carbon tipping points The Amundsen Sea from aboard RV Polarstern. Photo: Katharina Hochmuth. Researchers have found a long-searched for giant carbon reservoir buried in the Southern Ocean between Tasmania and Antarctica. The reservoir is the result of a dramatic carbon drawdown 34 million years ago that transitioned Earth […]

Voyage of discovery to the East Antarctic margin CSIRO research vessel (RV) Investigator and the team that are on their way to the East Antarctic margin. A Geoscience Australia-led scientific voyage has departed Perth this week for East Antarctica aboard CSIRO research vessel (RV) Investigator. During this 7-week voyage, researchers will seek insights into the flow […]

Scientists map heat beneath Antarctica’s icesheets Fieldwork in Queen Mary Land collecting geophysical and geological data. Image: Tobias Stål. Researchers from the ARC Centre for Excellence in Antarctic Science (ACEAS) at the University of Tasmania are helping predict future sea level rise by taking a closer look at what goes on beneath Antarctica’s icesheets. “Heat moving […]

Ocean warming and sea-level rise are on a fast track  The results of the study are based on many thousands of measurements taken from across the globe—including from the Southern Ocean, which warms at a much faster rate than the Pacific and Indian Oceans.
