The Copernicus Sentinel-1 radar mission shows how cracks cutting across Antarctica's Brunt ice shelf are on course to truncate the shelf and release an iceberg about the size of Greater London – it's just a matter of time.
Stay overnight on an Antarctic ice shelf, and you may feel the shaking from thousands of tiny quakes as the ice re-forms after melting during the day.
A small group of scientists and doctoral students from the University of California, Davis, recently returned from Antarctica, where they became the first group to collect turbulence measurements from an underwater glider ...
For the first time, a research team co-led by CIRES-based scientists, has directly observed an Antarctic ice shelf bending under the weight of ponding meltwater on top, a phenomenon that may have triggered the 2002 collapse ...
The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability.
In the West Antarctic Ice Sheet, which is particularly susceptible to influencing sea levels, rates of mass loss are especially sensitive near the point at which a glacier or ice shelf transitions into a regime of self-sustained ...
A team of ocean robots deployed in January 2018 have, over the past year, been the first self-guided ocean robots to successfully travel under an ice sheet and return to report long-term observations.
AWI researchers recently assessed subglacial lakes detected by satellite, and found very little water. But if that's the case, what is the source of the East Antarctic Ice Sheet's massive ice streams?
Large rock hills deep below glaciers can cause huge channels on the ice surface – even if the hills are buried under two kilometres of ice.
Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic "tones" scientists could potentially use to monitor changes in the ice ...
