In this ground-breaking all-action expedition, a team of leading scientists are in a race against time to discover the unknown world of icebergs. These frozen behemoths of the seas are among the Earth's most stunning natural phenomena and may even hold the key to the planet's shrinking icecaps. Yet no expedition has studied the birth and death of icebergs in such detail... until now. Following the iceberg from its gestation in the mother glacier, the team witnesses its dramatic moment as it calves off the glacier front. The team then follows the epic journey of an iceberg out at sea. From iceberg formation to the wildlife the iceberg harbours, the series searches for the secrets of the ice. Can they find the answers before the iceberg flips or shatters into thousands of pieces?
