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:

  • 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.
