Availability information for this program

CHANGING SEAS takes viewers on an exciting adventure to the heart of our liquid planet. The documentary series offers an unprecedented look at how oceanographers and experts study earth's vast underwater wilderness, while shedding light on how over-fishing, global climate change and pollution threaten ocean resources.

Episodes:

  • Maug's Caldera: A Natural Laboratory A Co-Production with Open Boat Films

    This episode takes viewers into an area of the remote Pacific, the islands of Maug. Formed by an ancient volcano, shallow hydrothermal vents are found close to coral reefs inside the submerged caldera. These vents emit levels of CO2 that can be expected in the world's oceans by the end of the century, making these waters a natural laboratory for scientists studying the impacts of ocean acidification on coral reefs.

  • Beneath The Bridge

    The Blue Heron Bridge in Riviera Beach, Florida is known as one of the best shore dives in the United States. Even though at first it appears as an unlikely dive site, it is home to a rich variety of marine life, ranging from tiny nudibranchs to manta rays. Underwater photographers are documenting what lives beneath the bridge, and a scientist is studying how two species of octopus co-exist there.

  • The Future of Seafood

    It is estimated there will be two billion more people on the planet by mid-century. To feed this booming world population, more fish will need to be farmed than ever before. One way to increase fish production in a sustainable way is to move aquaculture operations offshore - where there is plenty of available space and strong currents flush out the pens to avoid polluting sensitive ecosystems.

  • Toxic Algae: Complex Sources and Solutions

    Lake Okeechobee was once the blue heart of Florida, pumping fresh water down to the Everglades and beyond. But now that a dike and canal system control its flow, water releases from the lake periodically create putrid mats of blue green algae. Scientists think water pollution is to blame, and if something isn't done about it there could be irreparable damage to the environment, the local economy and people's health.

  • The Fate of Carbon

    For millennia, the exchange of CO2 between the oceans and atmosphere has been in balance. Now, with more anthropogenic carbon-dioxide in the atmosphere, the oceans are taking up more CO2 as well. This additional CO2 is negatively impacting sensitive ecosystems through a process called ocean acidification, and scientists worry how changes to the ocean environment will affect the way carbon is cycled through the seas.

  • Majestic Mantas

    The remote Revillagegdo Archipelago off Mexico's Pacific coast is a hotspot for giant mantas that interact with awe-struck scuba divers. Scientists are studying the local population using photo ID techniques and acoustic tags which track the movements of these mysterious fish. They are also conducting experiments to see if the filter-feeding rays are impacted negatively by microplastics, tiny pieces of toxic trash that float in the ocean.

  • Dolphins: Breaking The Code

    Dr. Denise L. Herzing has dedicated her career to studying a community of free-ranging Atlantic spotted dolphins that live in the shallow, crystal clear waters of the Bahamas Through non-invasive, in-water observation; she researches the animals' social structure, behaviors and communication. Now modern technology is making it possible to correlate the dolphins' sounds and behavior, bringing Herzing and her collaborators closer to decoding dolphin communication.

  • Cryptic Critters

    Deep underwater, on a shipwreck near Key West, lives a tiny potential new threat. Being in the right place at the right time, one expert spotted it and immediately knew that it didn't belong. Researchers want to know where this new species came from, and whether its sudden appearance spells disaster for the delicate coral reef ecosystem in the Florida Keys.

  • Lords of the Wetlands

    While American crocodiles are recovering in parts of their range, their future looks bleak in Jamaica. Habitat loss and poaching for meat have led to a drastic decline in the population. Dedicated scientists and conservationists are working to save the species through research, education, and conservation initiatives.

  • Fishing The Flats for Science

    Flats fishing is popular with recreational anglers in the Caribbean and the Florida Keys. But until recently, little was known about tarpon, bonefish and permit - the species most coveted by sports fishermen. Now scientists are studying the fish to better understand their movements, habitat, and spawning behaviors.

  • Billfish: Battle on the Line

    The unique oceanographic conditions of the eastern tropical Pacific make the area one of the best spots in the world for big game anglers to hook billfish. But intense pressures from commercial fishing operations have taken their toll on the numbers of sailfish and marlin in the region. Researchers are studying the animals to provide the data necessary to protect the fish populations from further decline.
