series description

The Emmy®-winning nature documentary series CHANGING SEAS focuses on timely issues affecting the world's oceans. Narrated by Peter Thomas, the series goes to sea with explorers and scientists as they use cutting-edge technology to study Earth's last frontier. Cameras venture into the blue alongside oceanographers and other experts seeking to better understand the threats facing oceans, including overfishing, global climate change and pollution. Season seven topics include: researchers beginning to understand where sea turtles go during their so-called "lost years,"; studying the impact of ecotourism might have on the wild fish of Grand Cayman's North Sound; protecting sailfish and marlin in the eastern tropical Pacific Ocean; and discovering the unique ways that fish species can change their sex.
