Southern Ocean takes on the heat of climate change Of all the oceans on Earth, the Southern Ocean does the lion’s share at slowing the pace of climate change by absorbing most of the excess heat trapped in the planet’s atmosphere, say scientists from the ARC Centre for Excellence in Antarctic Science (ACEAS) at UNSW […]

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.

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

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

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

Deep ocean currents around Antarctica headed for collapse, study finds Under a high emissions scenario, the collapse would stagnate the bottom of the world’s oceans. Photo credit: 66 north on Unsplash The deep ocean circulation that forms around Antarctica could be headed for collapse, say scientists. Such decline of this ocean circulation will stagnate the bottom of the

On Thin Ice: A science briefing about changes in Antarctic sea ice The Australian Antarctic Program Partnership (AAPP) and the Australian Centre for Excellence in Antarctic Science (ACEAS) have released a report on sea ice changes in Antarctica. Antarctic sea ice provides many services for our planet. It is a cooling sunshade, an insulating blanket, a unique habitat,

Seals to gather intel on the Southern Ocean Elephant seals are the ultimate divers—travelling long distances, and diving to 1500m depths. They are crucial to gathering knowledge on the Southern Ocean’s role in the global climate system. Photo: Clive McMahon, IMOS and SIMS.

New map unlocks deep digital data of Antarctica’s history By GNS Science It’s not just ice out there. 0.5% of the surface of Antarctica is exposed geology which can tell us a lot about the history – and the future – of the continent. GeoMAP Antarctica is the first detailed digital database that collates all

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
