Scientists release the most accurate, high-resolution terrain map ever created (2018)

  • The new map shows a much better look at the icy continent’s surface features, with a crisp resolution of 2 to 8 meters – compared to the previous standard of 1,000 meters.

How active are newly discovered Antarctic volcanoes?

A new volcanic province: an inventory of subglacial volcanoes in West Antarctica

...the biggest cluster of volcanoes in the world.


The study, published in the Geological Society Special Publications series, does not indicate whether the volcanoes are active but the team is trying to find out.

As Dr. Robert Bingham, a glacier expert and one of the paper's authors noted to the Guardian, "The big question is: how active are these volcanoes?"

"That is something we need to determine as quickly as possible," Bingham continued. "Anything that causes the melting of ice—which an eruption certainly would—is likely to speed up the flow of ice into the sea."

Ominously, other experts have warned that a reverse situation could also happen — volcanic activity can be triggered by thinning ice sheets from rising global temperatures.
