Satellite Captures Detaching Iceberg in Near-Real Time
NASA’s ICESat-2 satellite recorded the cleaving of a 315-billion-ton iceberg from Amery Ice Shelf in 2019, as well as years of subtle cracking and splitting prior to the calving event.
Beast of the Central Arctic
Feast your eyes on Beast, the first remotely operated vehicle to brave the Arctic for 1 year.
River Deltas at the Top of the World
The water that filters through river deltas has a large effect on the Arctic Ocean. A new study explores factors that shape Arctic river deltas and how delta form in turn changes water flow.
A Shared Resource for Studying Extreme Polar Environments
A new community pool of seismic instrumentation will facilitate and advance geologic and cryospheric research in Earth’s ice-covered environments.
Europe’s Mightiest Glaciers Are Melting
Here’s what a century of ice melt looks like on the Alps’ highest peak.
The Permafrost Listeners
Geophysicists have discovered a way to monitor permafrost thaw by measuring seismic waves so gentle they don’t shake a thing.
Using GPS Sensors to Capture Key Snowpack Properties
A low-cost, two-antenna GPS setup could enable valuable snow measurements in remote locations, improving predictions of runoff and avalanche risk.
Missing Lakes Under Antarctic Ice Sheets
New radio sounding study finds little evidence of lakes under Antarctica’s Recovery Glacier.
Subglacial Water Can Accelerate East Antarctic Glacier Flow
Airborne radar from the Recovery Glacier system demonstrates the importance of characterizing the underlying causes of ice flow speedup to understand how glacial discharge could change in the future.
