View ArticleGiant iceberg poised to snap off from Antarctica: scientists
An expanse of ice roughly the size of Delaware is close to breaking off from the warming Antarctic ice shelf to form one of the world's largest-ever icebergs, scientists said Thursday.
View ArticleAntarctic ice rift close to calving, after growing 17km in 6 days
The rift in the Larsen C ice shelf in Antarctica has grown by 17km in the last few days and is now only 13km from the ice front, indicating that calving of an iceberg is probably very close, Swansea...
View ArticleWave beams mix and stir the ocean to create climate
Ocean circulation patterns have a profound effect on global climate. Waves deep within the ocean play an important role in establishing this circulation, arising when tidal currents oscillate over an...

A Delaware-sized iceberg, one of the largest ever seen, was set adrift after snapping from a West Antarctic ice shelf that will be closely watched for signs of collapse, scientists said Wednesday.
View ArticleSentinel satellite captures birth of behemoth iceberg
Over the last few months, a chunk of Antarctica's Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the Copernicus Sentinel-1 mission, a lump of ice...
View ArticleAntarctic ice-mapping project will fly for the last time in October
In March 2002, when satellite images showed that 1300 square miles of Antarctica's Larsen B ice shelf—a slab bigger than the state of Rhode Island—had fragmented into a mass of floating ice chunks,...
View ArticleMathematical model calculates the collapse of shelf ice
Antarctic shelf ice consists of giant floating ice sheets that can span thousands of square kilometres. Pieces break off at their edges, forming icebergs in the ocean. In order to more effectively...
View ArticleWhat is storm surge and why is it so dangerous?
The biggest threat to human life during a hurricane is often the storm surge, which occurs when sea level rises dramatically during a storm, sending a wall of water gushing over land.
