Australian Antarctic expeditioners have discovered an enormous, two-kilometre-deep canyon underneath a glacier that may make it more vulnerable to warming oceans.

The voyage leader says the canyon may be allowing warming waters to get underneath the glacier

The discovery also indicates the Vanderford Glacier in East Antarctica once extended 60km further than it currently does and had a significant role in rising sea levels. "One of the issues for Antarctic glaciers at the moment is them being eaten away from underneath by warming waters coming down from the north."

"If there is a deep channel underneath this glacier, then it's possible that may not bode well for the Vanderford Glacier, but that of course requires further study," Mr Symons said.
