Giant Subglacial Canyons Found Beneath Antarctica

A network of 332 giant subglacial canyons has been revealed beneath the ice of Antarctica, with some reaching depths of over 4,000 meters.

The detailed mapping of the Antarctic seabed provides new insights into the history of glaciers, the circulation of ocean currents, and climate balance.

The canyons were formed by the action of glaciers and marine movements, acting as conduits for the transport of nutrients and currents.

Mapping shows differences between East and West Antarctica, suggesting different ice history.
