Beneath the white silence of Antarctica, where the ice has long suggested a frozen and inert land, a new digital archive now records 207 volcanoes hidden in the depths of the sheet. Published in early February by a China-led international team in the journal Earth-Science Reviews, the catalogue reframes the continent as a place of quiet fire, where heat rising from the earth shapes what happens to the ice above. Its significance lies less in the volcanoes themselves than in what they teach about the slow interplay between the planet's interior and its warming surface.
Antarctica's Ice Hides 207 Volcanoes, Mapped in First Comprehensive Subglacial Catalogue
Beneath those endless plains of ice, 207 volcanoes
Mark
So what's actually new here? Weren't there already volcanoes known under Antarctica?
Mimi
Yes, but they were scattered across separate studies. ANT-SGV-25 pulls them into one digital catalogue, described as the first comprehensive one, covering 207 volcanoes.
Mark
Why does it matter where they are?
Mimi
Eruptions under ice melt it from below instead of exploding upward. So location points to where the ice might be less stable.
Luke
Careful with that. The reporting says knowing locations helps identify areas at higher risk. It doesn't say any ice sheet has been destabilized by a volcano.
Mark
Fair. Are these volcanoes erupting?
Mimi
Some may be dormant and others might still be active. That's as precise as the article gets.
Luke
Right, and that's a real gap. We don't have a count of active ones here, so 207 shouldn't be read as 207 threats.
Mark
And the catalogue is open to everyone?
Mimi
It's called a public data product, so researchers worldwide can use it to model how geothermal heat interacts with ice flow.
Luke
One more caveat: the quote is reported secondhand through Live Science, and the article says more volcanoes may still be hidden. The number is a current tally, not a final one.
Der Puls
- A newly published catalogue has revealed 207 volcanoes buried beneath Antarctica's ice, overturning the picture of a geologically dead continent.
- Subglacial eruptions melt ice from below rather than erupting skyward, quietly threatening the stability of the ice above.
- Researchers now have an open dataset, ANT-SGV-25, to model how geothermal heat interacts with ice flow as the region warms.
- Scientists caution that the count may grow and that the activity status of many volcanoes remains unknown, so the work is still unfolding.
Beneath the white silence of Antarctica, where the ice has long suggested a frozen and inert land, a new digital archive now records 207 volcanoes hidden in the depths of the sheet. Published in early February by a China-led international team in the journal Earth-Science Reviews, the catalogue reframes the continent as a place of quiet fire, where heat rising from the earth shapes what happens to the ice above. Its significance lies less in the volcanoes themselves than in what they teach about the slow interplay between the planet's interior and its warming surface.
On February 3, the journal Earth-Science Reviews published a paper that gave a number to something Antarctica's surface never reveals: 207 volcanoes resting beneath the continent's ice. The count comes from ANT-SGV-25, a digital catalogue presented as the first comprehensive archive of the continent's subglacial volcanoes. It was developed by the Polar Research Institute of China with international partners, including the University of Exeter.
For a long time Antarctica was pictured as a frozen, geologically quiet plain. The catalogue suggests that picture was incomplete. Many of these volcanoes lie under kilometres of ice, which is why they went unnoticed, and the continent is now understood as one of Earth's major volcanic regions.
An eruption beneath ice does not burst into the sky. It melts the ice from below, and knowing where the volcanoes sit helps scientists flag areas where the ice may become unstable. The archive also works as a modelling tool, letting researchers study how geothermal heat meets ice flow in specific places, a question that matters more as the continent warms.
The number is unlikely to be final. Some volcanoes may be dormant and others still active, and more may be hiding beneath the ice. For now, the open dataset gives researchers a shared starting point.
On February 3, the journal Earth-Science Reviews published a paper that puts a number on something the surface of Antarctica gives no hint of: 207 volcanoes sitting beneath the continent's ice. The count comes from a new digital catalogue called ANT-SGV-25, which its authors present as the first comprehensive archive of Antarctica's subglacial volcanoes.
The work was led from China, developed by the Polar Research Institute of China, with international partners that include the University of Exeter. The Times of India, drawing on a Live Science report, describes the catalogue as a significant step forward for polar science.
The finding runs against a long-held picture of the continent. Antarctica has often been imagined as geologically quiet, a white and frozen plain. The reporting says that view no longer holds up, and that the continent is regarded as one of Earth's major volcanic provinces. Many of its volcanoes lie under kilometres of ice, which is why they are so easy to overlook.
The catalogue confirms 207 known volcanoes beneath the ice sheet. The source does not say how many of them are active. Some may be dormant, it notes, while others might still be active, and that open question is part of why the archive matters.
The physics of an eruption under ice differs from the dramatic image most people carry. Such an eruption does not blast into the sky. It melts ice from below. For that reason, knowing where the volcanoes are lets scientists identify regions at higher risk of ice instability.
The catalogue is also described as more than a map. It is a modelling tool, allowing researchers to study how geothermal heat interacts with ice flow in specific regions. That question gains weight as Antarctica warms. One scientist involved reportedly called ANT-SGV-25 a "public data product," a phrase that sounds dry but carries practical meaning: anyone in the global research community can use it.
The count is unlikely to be final. The report says more volcanoes may still be hiding under the ice. Future studies might refine estimates of how active these volcanoes are, or pinpoint the geothermal hot spots that matter most for the ice above them. For now, the catalogue gives researchers a shared starting point for that work.
