Using drones, laser scanners, and high-resolution models, researchers hope to find out more about the processes driving rapid melting in this region.

Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study.
A small team of scientists ventures out onto the Greenland ice sheet to study the forces large and small that are accelerating the melting of the world’s second-largest ice mass.
As climate warms, the Greenland ice sheet is melting, helping to fuel global sea-level rise. Follow a small team of scientists as they hike onto the sheet to investigate the forces large and small that are demolishing the ice.
Findings from last year indicate that the Greenland Ice Sheet is perhaps not as stable as scientists had hoped.
Scientists are collecting lake sediment, rock, water and plant samples to tease apart linkages between Arctic sea ice, atmospheric uptake, and changes in snowfall on the Greenland Ice Sheet.
As climate warms, the surface of the Greenland ice sheet is melting, and all that meltwater ends up in seasonal rivers that flow to the sea. At least that is what scientists have assumed until now. A new study has shown that some of the meltwater is actually being soaked into porous subsurface ice and held there, at least temporarily.
An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.
