The great ice streams of the Antarctic and Greenland are like frozen rivers, carrying ice from the massive inland ice sheets ...

Tiny ice quakes drive ice stream movement, reshaping our understanding of glacial flow and sea-level rise predictions.

An international team of researchers has shown that countless tiny ice quakes take place in one of Greenland's mightiest ice streams. This finding will allow the flowing of the ice sheet and ...

Urness: You mentioned that doesn’t necessarily mean an eruption like Mount St. Helens or Mount Mazama. Could you highlight ...

Quakes recorded for the first time inside Greenland's biggest frozen river, the Northeast Greenland Ice Stream, suggest this ...

This layer stops the quakes from propagating to the surface. Analysis of the ice core showed that these volcanic particles originate from a massive eruption of Mount Mazama in what is now Oregon (USA) ...

Urness: You mentioned that doesn’t necessarily mean an eruption like Mount St. Helens or Mount Mazama. Could you highlight any examples in your study area that was more explosive than it might ...
