Account of the ill-fated Canadian Arctic Expedition of 1913 when a group of scientists were sent to the Arctic to look for a new continent on the eve of WWI, an astonishing story of disaster and perseverance. On board were 10 scientists, 13 crewmembers, four Inuit hunters, one seamstress, her two children, and one passenger. Of these, 11 never returned and most were not heard from again until September 1914.

For many people, the Swiss Alps are a natural paradise. But in fact this paradise in man-made. Alpine meadows exist only because farmers have been driving their livestock up into the mountains for centuries. Now the ancient traditions are disappearing and the forest is spreading more and more.

We are all seeing rather less of the Sun. Scientists looking at five decades of sunlight measurements have reached the disturbing conclusion that the amount of solar energy reaching the Earth's surface has been gradually falling. Paradoxically, the decline in sunlight may mean that global warming is a far greater threat to society than previously thought.

Sonic Sea is a documentary about the devastating impact of industrial and military ocean noise on whales and other marine life. The film begins with a mystery: the unexplained stranding and mass mortality of several species of whales in the Bahamas in March 2000. As the mystery unfolds, the film explores the critical role of sound in the sea, and the sudden, dramatic changes human activity is inflicting on the ocean's delicate acoustic habitat -- changes that threaten the ability of whales and other marine animals to prosper, to function, and ultimately, to survive. Sonic Sea features several charismatic scientists, including Ken Balcomb, the former Navy pilot and acoustics expert who proved to the world that naval sonar is killing whales, as well as the musician and environmental activist, Sting, whose moving interview connects the sonic world of marine life with our sonic world on land. The film offers solutions (and, by extension, hope) for a quieter ocean, and underscores that the ocean's destiny is inextricably bound with our own.
