All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.

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.
