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.
