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, […]

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 […]

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 […]
