The Fate of the Greenland Ice Sheet: Deep Learning from SkySat Images
Surface meltwater ponding and drainage in the Greenland Ice Sheet is analyzed at high spatial and temporal resolution through SkySat imagery and deep learning.
A Long-Term Look Beneath an Antarctic Ice Shelf
More than 4 years of data from a borehole in the Ross Ice Shelf reveal supercooled water and more.
Greenland Dust Delivers Nutrients to Ice-Melting Algae
Researchers scrutinized aerosols above and within the ice sheet, finding phosphorus and other mineral particles.
These South Pole Seismometers Will Detect Vibrations 1.5 Miles Under the Ice
The instruments will freeze into Antarctica’s ice sheet, where they will collect detailed, global-scale seismic data.
Sediments Offer an Extended History of Fast Ice
Scientists used sediments to create a millennia-long archive of Antarctic fast ice. Along the way, they discovered that the freezing and thawing of this enigmatic ice appear to be linked to solar cycles.
Snowball Earth’s Liquid Seas Dipped Way Below Freezing
Iron isotopes show that salty seawater pockets beneath the ice were as cold as −15°C.
Los glaciares se están calentando más lentamente de lo esperado, pero no por mucho tiempo
Un conjunto de datos sin precedentes ofrece información sobre el efecto de enfriamiento contraintuitivo de los glaciares a escala global.
Melting Glaciers Mix Up Waters More Than We Thought
Existing theory underestimates the mixing of freshwater and seawater by up to 50%.
Hundreds of Scientists “Vehemently Oppose” U.S. Effort to Purchase Greenland
More than 200 scientists scientists have signed a letter condemning U.S. President Donald Trump’s efforts to acquire Greenland.
