A massive, hidden structure buried two miles beneath Antarctica’s ice could rewrite its history
Under nearly two miles of Antarctica’s ice, scientists have identified a massive buried geological feature that could change how researchers interpret the continent’s history and what might happen to it next.
As reported FuturismThe discovery could also help studies beyond the continent by giving researchers a better look at how massive ice sheets respond to rising global temperatures.
What happened?
Scientists have discovered a massive hidden structure beneath the surface of the East Antarctica ice sheet and published their findings in a journal He studies In the peer-reviewed journal Nature Geoscience.
The researchers’ discovery represents one of the largest formations of its kind on Earth under the ice of Antarctica. The team of scientists has named it the fan-shaped East Antarctic Basin Province, which now connects several subglacial features previously known to scientists, including the world’s largest subglacial lake, Lake Vostok.
Other components of this geological structure include the Wilkes and Aurora subglacial basins, along with Lake Vostok. According to A press release For the new Nature paper, these configurations were not considered components of the same structure.
To map the province, the researchers collected several sets of data, including geological observations, gravity readings, magnetic information, and models of the Earth’s crust.
Taken together, the evidence suggests that the buried formation likely developed through “distributed rotational extension,” which Futurism suggested described As a process of continental crust gradually extending outward over millions of years.
Why does it matter?
Because the province extends over much of East Antarctica, it may affect the way the overlying ice changes, melts and responds to the terrain beneath.
Since Antarctica’s ice sheets play a major role in rising sea levels, better knowledge of the geology that directs ice flow could improve predictions of future sea level rise.
Additionally, as rising temperatures destabilize ice, uncertainty can slow preparedness efforts and make it difficult for communities to protect homes, roads, drinking water systems, and local economies from worsening flood risks.
Essentially, what lies beneath Antarctica could shape how one of Earth’s largest glaciers changes above it, and how well the rest of the world can prepare for what comes next.
