Antarctic Glaciers Surged After 1995 Ice Shelf Collapse

Publication: National Geographic News   Date: March 6, 2003   View Article

When a huge floating shelf of ice hinged to the northern end of the Antarctic Peninsula disintegrated in January 1995, several glaciers that were backed up into it surged towards the sea, according to a pair of Argentinean researchers.

The discovery marks the first positive evidence that glacial surge follows an ice shelf collapse. It may lead scientists to revive the previously discarded theory that ice shelves acts as dams that prevent inland glaciers from slipping into the seas.
