Summary
An international team led by University of Genoa geophysicist Egidio Armadillo mapped a giant province of about 30 connected basins beneath East Antarctica.
The finding brings together work by geophysicists, geologists and glaciologists, indicating the buried landscape is a linked basin system rather than isolated features.
East Antarctica is the focus of the new map, which identifies a vast subsurface structure hidden under the continent's ice.
How will this hidden Antarctic map force us to rethink the future of our planet's ice sheets?
What other giant geological structures might lie undiscovered beneath Earth's ice, and what secrets do they hold?
Does this vast, fan-shaped basin reveal a new blueprint for how continents break apart?
Discovery of the East Antarctic Fan-shaped Basin Province: Unveiling a Giant Subglacial Structure Shaping Ice Sheet Dynamics and Global Climate
Overview
An international team of scientists has discovered a massive, previously unknown geological feature beneath the East Antarctic Ice Sheet, called the East Antarctic Fan-shaped Basin Province (EAFBP). This giant, fan-shaped structure was revealed through a rigorous scientific effort that combined detailed subglacial topography, geological observations, gravity and magnetic measurements, seismic data, and advanced models of the Earth's crust and lithosphere. By integrating these methods, researchers were able to map out the EAFBP and confirm its unique geometry, marking a major advancement in our understanding of Antarctica's hidden landscape and geological history.
