The breaking (calving) of icebergs from ice shelves is part of a natural, cyclical process of growth and decay at the limits of Earth’s ice sheets. As glacial ice flows from land and spreads out over the sea, shelf areas farthest from shore grow thinner. These areas are stres...

These companies want the ice for its Arctic purity: the water in these icebergs is around 12,000 years old and probably contains very few pollutants. For millennia, this water has lain trapped and preserved in the glaciers of Greenland, only recently breaking off in chunks and drifting sou...
Calving, when chunks of ice break off from ice shelves to form icebergs, is common and increasingly influenced by climate change. For extremely large icebergs, this process is typically slow, often starting with small rifts that spread across the ice shelf before fully breaking off. These...
Ice shelves commonly feature crevasses. Extremely large cracks occasionally form when the shelf breaks in the summer but then partially heal in the winter as the sea freezes and snow accumulates. These cracks sometimes begin to grow again, which can lead to vast icebergs breaking off in...
