3.   But Michael Oppenheimer, senior scientist at the Environmental Defense Fund in New York, said policymakers ignore the retreating Antarctic ice at their peril.

4.   But, as Iverson pointed out, there are many scientists and satellites keeping an eye on the vast Antarctic ice shelves and their potential to raise ocean levels.

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

6.   Few of us can really imagine what the collapse of this small fraction of the Antarctic ice sheet must have been like.

7.   His research included helping to determine the mass of the Antarctic ice sheet.

8.   It suggested how contaminants from the Antarctic ice could have misled scientists into thinking they had found the first sign of Martian organic molecules.

9.   Many of them were knocked loose from the Antarctic ice sheet when Godzilla bumped into the massive Ross Ice Shelf that extends from the frozen continent.
