Giant Trench under Antarctic Ice

Researchers have discovered a giant trench, deeper than the Grand Canyon, buried beneath the Antarctic ice.    Newcastle University

The findings are published in the latest edition of the Geological Society of America Bulletin.



The massive valley is up to 3 kilometres deep, more than 300 kilometres long and up to 25 kilometres across.

The paper’s lead author Dr Neil Ross from Newcastle University said:

“The discovery of this huge trough, and the characterisation of the surrounding mountainous landscape, was incredibly serendipitous.

We had acquired ice penetrating radar data from both ends of this huge hidden valley, but we had no information to tell us what was in between. Satellite data was used to fill the gap, because despite being covered beneath several kilometres of ice, the valley is so vast that it can be seen from space.



To me, this just goes to demonstrate how little we still know about the surface of our own planet. The discovery and exploration of hidden, previously-unknown landscapes is still possible and incredibly exciting, even now.”
