Melting ice sheets are slowing the Antarctic Circumpolar Current (ACC), the world’s strongest ocean current, researchers have found.This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems.
The researchers, from the University of Melbourne and NORCE Norway Research Centre, have shown the current slowing by around 20 per cent by 2050 in a high carbon emissions scenario.

Using drones, 17 distinct behaviors of narwhals were captured in the wild. Findings reveal complex behaviors of the Arctic’s iconic whale never seen before. This highly gregarious whale uses its tusk to investigate, manipulate and influence the behavior of a fish, the Arctic char. The study also provides the first evidence of play, specifically exploratory-object play, and the first reports of kleptoparasitism, a “food thief” situation, among narwhals and glaucous gulls.
26.02.2025/Kiel. The south-western Baltic Sea has about 3,000 kilograms of dissolved toxic chemicals released from unexploded ordnance, according to a new study by the GEOMAR Helmholtz Centre for Ocean Research Kiel. The substances were detected in almost all water samples taken in 2017 and 2018, with particularly high concentrations in the Bights of Kiel and Lübeck. The levels are still below thresholds for health risk, but highlight the urgent need for munitions clearance to minimise long-term risks. The study has now been published in the journal Chemosphere.
An Osaka Metropolitan University research team observing anemonefish in the field found they engage in interesting feeding behavior with their host sea anemones.
New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth’s surface and paving the way for complex life to flourish.
By chemically analysing crystals in ancient rocks, the researchers discovered that as glaciers carved through the landscape, they scraped deep into the Earth’s crust, releasing key minerals that altered ocean chemistry.
This process had a profound impact on our planet’s composition, creating conditions that allowed complex life to evolve.
