The A23a is the world's largest iceberg: nearly 4,000 km2, twice the size of London and three times the size of New York. Born in 1986, this ice giant has been drifting in the Southern Ocean for almost 40 years. Today, it is heading dangerously towards South Georgia, endangering not only the island's ecosystem but also the lives of its passengers.
Many animals regularly stop off on the gigantic iceberg, attracted by the organic matter carried by its ice. Here, seals, penguins and seabirds nest and breed by the thousands. But now they face a double threat. Not only is the A23a beginning to break up under the effect of the warm waters of the Southern Ocean, but its collision with the British island is imminent. What will happen to the animals on board?
Combining satellite and underwater footage, this documentary takes us on a sensational odyssey aboard this immense raft of ice, to meet its passengers with uncertain fates.
