Ms. Ferrigno said four other extensions of the continental ice had gone to sea in the last few years, as well.

Before they broke off from the continental ice the icebergs had scraped up rocky debris from land beneath the ice, then deposited it as "dropstones" when melted over this spot.

Indeed, the power of ice age meltwater, which rushed for millennia from unfathomable fountainheads of continental ice, shaped Interstate Park's billion-year-old basalt like clay on a spinning wheel.

The shield margins have been sculpted by continental ice, and its uppermost member includes volcano-glacial facies.

Another explanation for the sudden temperature changes seen in the Greenland ice cores is large-scale slippages, or "surges," of continental ice into the sea.

Melting of continental Antarctic ice could contribute to global sea level rise.

Embedded in Antarctic ice, a balloon, like any other object, has to travel seaward with the gradual downward flow of continental ice.

It drains northeastward from the continental ice but turns northwestward at the coast where it terminates in a prominent tongue close east of Cape Waldron.

Estimates of the volume increase due to ocean warming give a rate of about 0.5 mm/yr and the rate due to mass increase, primarily from the melting of continental ice, is thought to be even smaller.

In order of increasing age, these advances took place during the Wisconsinan and Illinoian stages; prior to this continental ice sheets advanced into and retreated from Minnesota multiple times during the Pre-Illinoian Stage.
