Cold Days Bring Fast Ice

by Saima May Sidik 20 December 202420 December 2024

Thirty-seven years of observations reveal the meteorological conditions that lead to persistent, thick fast ice in Antarctica.

Greenland Ice Sheet Stores Hidden Water Throughout the Melt Season

by Matthew R. Francis 19 December 202419 December 2024

A new method uses stations around Greenland’s coast to measure how much meltwater weighs down the bedrock beneath the ice, improving our understanding of its contribution to sea level rise.

Mantle Motion Matters for Mapping Modern (and Ancient) Ice

by Alka Tripathy-Lang 11 December 202411 December 2024

Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers trying to properly parse past mantle movement.

The Survival of Arctic Sea Ice May Depend on Its Travel Routes

by Mahima Samraik 9 December 20249 December 2024

Researchers find that the motions of ice parcels determine which ones survive the annual summer melt.

Tourism and Distant Fires Affect Antarctica’s Black Carbon Levels

by Larissa G. Capella 18 November 202418 November 2024

Tourism and biomass burning in the Southern Hemisphere are boosting black carbon levels and accelerating ice melt in Antarctica.

Glaciers near Active Volcanoes Flow Faster

Katherine Kornei, Science Writer by Katherine Kornei 14 November 202414 November 2024

Monitoring glacier velocity could help predict volcanic activity, a study of more than 210,000 glaciers suggests.

Structural Inversion of an Intracratonic Rift System in Deep Time

by Alexis Ault 31 October 202431 October 2024

A new study reconstructs how an ancient North American rift system was uplifted in space and time due to subsequent continent-continent collision.

Each Glacier Has a Unique Organic Matter Composition

by Saima May Sidik 15 October 202415 October 2024

Like snowflakes, no two glaciers are alike: Carbon-containing compounds released from glaciers vary from place to place, meaning climate and ecosystem effects of melting could vary as well.
