shelf ice

Icebergs are huge, thick hunks of ice that break off glaciers or shelf ice and float to sea.

At a distance, large bergs would be undistinguishable from shelf-ice, appearances of which were reported above.

Wild, Harrison and Hoadley went to examine the shelf-ice with a view to its suitability for a wintering station.

In all, thirty-six tons of stores were raised on to the shelf-ice, one hundred feet above sea-level, in four days.

The shelf-ice is without doubt afloat, if the presence of sea-water and diatomaceous stains on the ice is of any account.

Thus the northern face crumbles down into brash or floats away as part of a berg severed from the main body of the shelf-ice.
