At the fringes of the Greenland Ice Sheet, where glaciers are constantly melting, water rushes everywhere through an intricate system of lakes and streams that branch out like slip and slide shoots of super chilled, bright turquoise water. Some of that water eventually cascades straight into the surrounding land and […]

Archean Maniitsoq structure in Greenland. Credit: University of Waterloo 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 normal geological processes. During fieldwork at the Archean Maniitsoq structure in Greenland, an international team of […]
1985 – 2015 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. Some of those changes are causing the rerouting of freshwater rivers beneath the ice. In a study led by Twila Moon of the […]
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 contribution. Outlet glaciers are rivers of ice flowing within the cracks of the bedrock and draining into the surrounding sea. They retreat and start to […]
A seismic station on the Greenland Ice Sheet installed by authors. Snow accumulation in one year is ~1.5 m, and the solar panels are buried in the snow. Snow removal and maintenance are done manually by several people. Credit: Genti Toyokuni A team of researchers understands more about the melting […]
The suggested valley and possible river flowing from the deep interior of Greenland to Petermann Fjord deep below Greenland’s ice sheet (500 meters below sea level). Credit: Christopher Chambers et al, The Cryosphere, November 12, 2020 Computational models suggest that melting water originating in the deep interior of Greenland could […]
The largely featureless surface of the Greenland ice sheet, as seen from the window of a P3 aircraft carrying geophysical instruments aimed at detecting geologic features underneath. Credit: Kirsty Tinto/Lamont-Doherty Earth Observatory Inaccessible for now, unique site may hold secrets of past. Scientists have detected what they say are the […]

If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of […]
This aerial photograph shows fast-moving meltwater rivers flowing across the Greenland Ice Sheet, a region that, combined with Antarctic meltwater and thermal expansion, accounts for two-thirds of observed global mean sea level rise.
