Svalbard

Set in three of the most seasonally changeable landscapes on earth - Svalbard, Okavango and New England - this series showcases the stunning transformations that occur each year, revealing the unique processes behind them and showing how wildlife has adapted to cope with the changes.

Svalbard in the Arctic spends many months of the year in complete darkness, an unrelenting frozen winter with temperatures down to -40 Celsius. But when the sun finally reappears, the landscape magically transforms from an ice world into a rich tundra, full of exotic plants, birds, Arctic foxes, polar bears, walruses and reindeers. This film captures the changes in all their glory and reveals how this transformation is only possible thanks to some bizarre microorganisms that feed on ice and the stunning abilities of migrating birds.
