New Study Shows Antarctic Waters Unleashed Ancient Carbon at the Ice Age’s End
New research shows that shifting Antarctic circulation after the last Ice Age released ancient deep-ocean carbon into the atmosphere. Using Southern Ocean sediment cores, scientists traced how expanding Antarctic Bottom Water mixed long-isolated, carbon-rich waters upward. The findings reveal a major but underappreciated driver of early Holocene wa...

Scientists Warn Southern Ocean Could ‘Burp’ Stored Heat, Delaying Global Cooling for 100 Years
New modelling suggests the Southern Ocean could one day release the vast heat it has stored from greenhouse gas pollution. If CO₂ levels were pushed to net-negative, deep convection may trigger a sudden “thermal burp” that warms the planet for decades. Though idealised, the study shows how Antarctica’s surrounding seas could shape long-term...

A Technique That's Helping Experts Find Out Changes In Oceans. It's Not Robots Or AI
The ocean stores most of the heat energy put into the atmosphere from human activity. So, understanding how this heat moves around helps researchers monitor oceans around the globe.

Exoplanet Oceans Could Flow In Reverse - Creating Very Strange Climates, Scientists Say
With the explosion of exoplanet discoveries in recent years, we are learning more and more about what the universe can produce - inevitably sparking a Saganesque mix of science and sheer imagination, as researchers try to apply what they know about the Earth's workings to discern what's possible elsewhere.

US Calls for More Efforts to Protect Oceans
US Secretary of State John Kerry said the oceans are facing threats from over-fishing, pollution and acidification, and called for "a comprehensive, global strategy" to protect them, media reported on Tuesday.
