We headed out a few miles onto the ice shelf.

The ice shelf appears in the middle of the images.

They were on an ice shelf a few hundred yards down.

The finding may also have some implications for the future of the ice shelf itself.

Canada has lost approximately 90% of its ice shelves in the last hundred years.

The finding indicates that this part of the ice shelf had been open water at least once before.

"That means we're now on a floating ice shelf which could break apart at any moment!"

And then the ice shelf crumbled from beneath them both.

This water is just warm enough to cause significant melting at the bottom of the ice shelves.

All of them were sliding in the same direction, out from the ice shelf and away over the ocean floor.

Some believe that various forces may compromise the internal strength of the ice shelves.

It was the tenth major ice shelf to collapse in recent times.

A warmer ocean may have a dramatic effect on the ice shelf.

That facility will support helicopter operations to the ice shelf.

Finally, a March 7 image shows that most of the ice shelf had disintegrated.

The Antarctic peninsula has lost a number of ice shelves recently.

The ice shelf is now 40% the size of its previous minimum stable extent.

The thickness of ice shelf was reported to be about 150 metres in this region.

The top image, acquired just before the breakup, shows the intact ice shelf.

If this process continues for something on the order of a decade, the ice shelf will probably disintegrate.

Last summer, he spotted several new islands in an area where a massive ice shelf had broken up.

Instead, the sea water freezes to the ice shelf.

Second, the ice shelf is breaking into larger chunks than had been observed previously.

Considering recent ice shelf collapses, this research is relevant to current events.

The collapse reduced the ice shelf by 60 percent.
