Wind-blown Antarctic sea ice helps drive ocean circulation

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than ...

Tracing deep ocean currents

Radioactive isotopes typically take four years to reach the Norwegian coast from Sellafield on the north-eastern coast of England. Researchers like Yongqi Gao follow the radioactive waste to understand how ocean currents ...

Heat release from stagnant deep sea helped end last Ice Age

The build-up and subsequent release of warm, stagnant water from the deep Arctic Ocean and Nordic Seas played a role in ending the last Ice Age within the Arctic region, according to new research led by a UCL scientist.

Sun's activity controls Greenland temperatures

The sun's activity could be affecting a key ocean circulation mechanism that plays an important role in regulating Greenland's climate, according to a new study. The phenomenon could be partially responsible for cool temperatures ...

Air bubbles could keep rivers open for shipping

Researchers at EPFL have shown how air bubbles could keep sediments from obstructing bends in river waterways such as the Rhine River, which has to be dredged regularly to stay open for freight ships.

Global warming won't mean more stormy weather

A study led by atmospheric physicists at the University of Toronto finds that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will ...
