NASA Astrobiology: Probing for Life in the Icy Crusts of Ocean Worlds
A technique for scanning Mars rocks for microscopic fossils of ancient life is also being developed to hunt for microbes in the deep ice of…
What a Glacial River Reveals About the Greenland Ice Sheet and Global Sea Level Rise
With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control…
Thick Sea-Ice Warms Greenland Fjords
A new study shows that thick sea-ice can increase the sensitivity of Greenlandic fjords to climate warming. Understanding the factors that control how fast glaciers…
Satellite Data Shows Lakes on Greenland Ice Sheet Can Drain Huge Amounts of Water, Even in Winter
Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter,…
Intact Plant Fossils Discovered Beneath Greenland’s Ice Sheet After Lucky Find of Ice Cores Drilled by U.S. Military in 1966
For the first time ever, researchers have found fossils under Greenland’s ice sheet that are so large and well preserved that they can be seen…
Complex Behavior of a Turbulent Plume at the Calving Front of a Greenlandic Glacier
For the first time, scientists have succeeded in continuous monitoring of a subglacial discharge plume, providing a deeper understanding of the glacier-fjord environment. As marine-terminating…
Scientists Stunned to Discover Plants Beneath Mile-Deep Greenland Ice – Why This Spells Trouble
Long-lost ice core provides direct evidence that giant ice sheet melted off within the last million years and is highly vulnerable to a warming climate….
Oops! The “World’s Oldest Meteorite Impact Crater” Isn’t an Impact Crater After All
Several years after scientists discovered what was considered the oldest crater a meteorite made on the planet, another team found it’s actually the result of…
NASA’s OMG: Warming Seas Are Accelerating Greenland’s Glacier Retreat
Scientists with NASA’s Oceans Melting Greenland mission are probing deep below the island’s warming coastal waters to help us better predict the rising seas of…
Our Planet Is Losing Ice at Record Rate – In Line With the Worst-Case Climate Warming Scenarios
A research team – the first to carry out a survey of global ice loss using satellite data – has discovered that the rate at…
Warming Seas Are Undercutting Sverdrup Glacier in Northwest Greenland
Warming seas are accelerating the retreat of Greenland’s coastal glaciers. Sverdrup Glacier in northwest Greenland is pretty average. It is a textbook example of the…
Shrinking Margins of Greenland: At Least 200 Coastal Glaciers Have Retreated Over the Past 20 Years
A recent study of Greenland’s ice sheet found that glaciers are retreating in nearly every sector of the island, while also undergoing other physical changes….
NASA Finds What a Glacier’s Slope Reveals About Future Greenland Ice Sheet Thinning
As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise…
Newly Discovered Greenland Hot Rock Mantle Plume Drives Thermal Activities in the Arctic
A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle…
Scientists Find “Knickpoints” in Greenland That Can Stop Spread of Glacial Thinning
The jagged terrain of Greenland’s mountains is protecting some of the island’s outlet glaciers from warm coastal waters, according to a team of researchers that…
Researchers Investigate Giant Holes in Greenland Ice Sheet
Researchers climbed into moulins, which drain meltwater from the ice sheet, to better understand how volume relates to ice movement. Holes that carry surface meltwater…
A 1,000 km Long River May Be Flowing Deep Below Greenland’s Ice Sheet
Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at…
