Seashells and Penguin Bones Reveal Thwaites Glacier’s Quiet Past
Antarctica’s Thwaites and Pine Island Glaciers are melting faster than they have in the past 5,500 years, new evidence shows. Against expectations, their pasts have been remarkably stable.
Los Himalayas atraviesan por una “excepcional” pérdida de masa glaciar
Los Himalayas han perdido 40% de su masa glaciar desde la Pequeña Edad de Hielo. El Este de Nepal y Bután han sufrido pérdidas de forma más acelerada.
Precession Helped Drive Glacial Cycles in the Pleistocene
By studying bits of rock scooped up by ancient glaciers, researchers have pinned down that recent glacial variability was driven, in part, by changes in the direction of Earth’s axis of rotation.
Circling Antarctica to Unveil the Bed Below Its Icy Edge
An international initiative aims to collect a comprehensive airborne data set from the Antarctic Ice Sheet margin to better estimate ice discharge and sea level contributions today and in the future.
Massive Groundwater Systems Lie Beneath Antarctic Ice
Scientists are updating ice stream models to understand the ways in which deep groundwater systems impact ice flow.
Newly Discovered Lake May Offer a Glimpse into Antarctica’s Past
Scientists dive in—metaphorically—to Lake Snow Eagle, only recently revealed through ice-penetrating radar.
Charting Paths to New Knowledge
In our June issue of Eos, we home in on the unique ways researchers are using maps to better understand Earth and beyond.
Glacial Knowledge Gaps Impede Resilience to Sea Level Rise
Changes to the support, culture, and community organization of U.S. glaciology are needed to advance understanding of glacial change and better predict rising seas and other ice loss impacts.
Una nueva pista sobre el colapso de la plataforma de hielo antártica
Un tipo particular de tormenta coincidió con 13 de los 21 eventos recientes de desprendimiento en la Antártida.
