Antarctica’s buried terrain mapped in unprecedented detail, reshaping sea‑level forecasts
Scientists mapped Antarctica’s subglacial terrain in unprecedented detail, revealing tens of thousands of previously unknown hills and ridges and a deep channel in the Maud Subglacial Basin about 50 meters deep, 6 kilometers wide, and 400 kilometers long; the work, published in Science and led by Helen Ockenden of Grenoble Alpes University, helps explain how buried features steer glacier flow and retreat and will refine predictions of future sea-level rise.
