ICE NOMADS

The A23a is the world's largest iceberg: 4,000 km², twice the size of London and three times the size of New York. Formed in 1986, this gigantic block of ice is now beginning its drift, leaving Antarctica for the warmer waters of the Southern Ocean. On board, a host of passengers. 

Indeed, many animals stop over on this frozen island, attracted by the organic matter carried by its ice - millions of seals, penguins and seabirds nest and breed here.

Combining superb satellite and underwater shots, this documentary takes us on a formidable odyssey aboard this immense raft of ice, to meet its passengers with uncertain destinies.
