Novel observations and inventive analyses of glacial discharge in Greenland have revealed new insights into the irregular and chaotic nature of ice-ocean interactions at glacial calving fronts.
Instruments and techniques
The Catcher in the Ice
There are three ways to extract gases from an ice core. The cleanest one, sublimation, is getting easier.
Tuning in to a Glacial Symphony
New research focuses on the bubbling and bathtub-like sounds of a glacier.
Light Permeates Seasonally Through Arctic Sea Ice
The transmission of sunlight through Arctic sea ice depends on the presence of ice, snow, and melt ponds, data collected over 6 years reveal.
The Permafrost Listeners
Geophysicists have discovered a way to monitor permafrost thaw by measuring seismic waves so gentle they don’t shake a thing.
How Ice Cores Are Helping to Track Preindustrial Ozone
Research helps allay concerns about discrepancies between atmospheric chemistry models and historical direct measurements.
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.
What’s Missing from Antarctic Ice Sheet Loss Predictions?
Accurately modeling melt rates in specific ice shelf locations is critical for forecasting how Antarctica’s ice sheet will respond to climate change.
Extending the Record of Surface Melt on the Larsen C Ice Shelf
The first use of Advanced Scatterometer radar data to determine melt duration on an Antarctic ice shelf shows the season has decreased by up to 2 days per year during the extended 21st century record.
Cosmic Ray Neutrons Reveal Mountain Snowpacks
The first application of aboveground neutron sensing to evaluate alpine snowpacks indicates that this method can reliably detect average snow depth and water content across intermediate distances.
