Operation Iceberg

Episode 1

Birth of a 'Berg

A British-Cavadian team of scientists, including BBC presenter Chris Packham, arrives at Greenland's western coast to study the country's largest glacier and the icebergs it gives birth to, a spectacular process, yet never extensively studied. A former explosives expert takes the lead in most physically dangerous operations, as to plant scientific recording equipment at perilously unstable and inaccessible spots. Combined with observations from a boat on and dangerously close to the surrounding sea, they find the part played by melting water forming lakes on the glacier top, canals to the rock underground and maritime circulation.
