Recent ice loss from the West Antarctic Ice Sheet has been caused by ocean melting of ice shelves in the Amundsen Sea. Eastward wind anomalies at the shelf break enhance the import of warm Circumpolar Deep Water onto the Amundsen Sea continental shelf, which creates transient melting anomalies wi...
Increased melting of West Antarctica's ice shelves is "unavoidable" in the coming decades, a new study has warned. These floating tongues of ice extend from the main ice sheet into the ocean, and play a key role in holding back the glaciers behind. But as ice shelves melt, it can mean...
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels.They compared these results to evidence of how temperatures and currents actually changed during that time.The model showed that if it was only in the northern hemisphere that ice melt...
Surface melting is a rare event across Antarctica and melt features preserved in the ice sheet stratigraphy provide a unique paleoclimate record of changes in summer temperature. We have analyzed the visible stratigraphy of the Siple Dome deep ice core and use the record of melt layers to ...
The primary Antarctic contribution to modern sea-level rise is glacial discharge from the Amundsen Sea sector of the West Antarctic Ice Sheet. The main processes responsible for ice mass loss include: (1) ocean-driven melting of ice shelves by upwelling

A large section of the mighty West Antarctic ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of researchers recently reported. The1scientists say that means even more sea level rise than they figured.One of the studies, led by NASA glacio...
West Antarctic ice sheet may be uniquely capable of rapid deglaciation (melting), and many scientists are quite concerned about this possibility. If the WAIS was to melt and disappear it would raise sea level by an average of 6 metres (19.6 feet).After a decade of satellite measurements the...
