Where icebergs come from

The giant tabular icebergs around Antarctica break off the floating ice shelves at the edge of the ice sheet, a natural part of the shelves’ life cycle. Ocean currents carry them around the continent for years as they slowly melt and break apart; the National Ice Center tracks every one at least 10 nautical miles long.

Did you know?

Watched from orbit. Icebergs are tracked by satellite. The National Ice Center names Antarctic icebergs once they are at least about 10 nautical miles long.

Data: U.S. National Ice Center via NASA EONET.
