Research news on ice sheet

An ice sheet, as a geophysical substance, is a massive, contiguous body of glacial ice that covers more than 50,000 km² and is sufficiently thick (often >2–3 km) for its internal deformation and basal sliding to dominate flow dynamics. Composed primarily of recrystallized freshwater ice with embedded air bubbles, dust, and minor impurities, it exhibits anisotropic rheological behavior described by non-Newtonian creep laws (e.g., Glen’s flow law). Ice sheets thermally stratify between cold and temperate regimes, store the majority of Earth’s terrestrial freshwater, and interact with bedrock and subglacial hydrological systems, influencing isostasy, basal lubrication, and large-scale mass balance.

Antarctic drilling peers deep into ice shelf's past

Scientists say they have drilled deeper than ever beneath the West Antarctic Ice Sheet, peering back millions of years to reveal signs it was once, at least in part, open ocean.

Greenland ice melt surges unprecedentedly amid warming

A study led by the University of Barcelona and published in the journal Nature Communications shows that climate change has profoundly altered extreme episodes of melting in the Greenland ice sheet by making them more frequent, ...

AI to track icebergs adrift at sea in boon for science

British scientists said Thursday that a world-first AI tool to catalog and track icebergs as they break apart into smaller chunks could fill a "major blind spot" in predicting climate change.
