As the glacier's grounding line continues to sink farther down the canyon (which already sits below sea level), warm ocean water will batter larger and larger chunks of the glacier's edge, causing it to melt even faster and make the precarious ice shelf above even more vulnerable to collapse. Right now, that canyon (known as the Denman trough) is mostly cut off from the sea thanks to all the glacial ice piled inside and atop the ravine. Australien gör anspråk på området.
