Jonathan Bird's Blue World

Host Jonathan Bird travels to the Bahamas, where, in the past few years, diver interactions with Tiger sharks have become up close and personal. These large and dangerous animals are not only being hand-fed, but actually handled by divers. Jonathan learns how to flip a Tiger shark from experienced shark handlers.

Jonathan travels to Iceland to investigate a giant crack in the ground filled with frigid runoff from melting glaciers. It's rumored to be the clearest water in the world. But to find out, Jonathan has to brave some very cold water. Next, he heads down to sunny Florida, not to dive a coral reef or a spectacular shipwreck, but to dive in shallow, murky water under a busy bridge.

Jonathan joins an expedition to recruit a new Blue World camera operator in the form of a 1,000 pound Tiger shark! Working with experienced shark handlers, he puts a camera on the dorsal fin of the shark to see what it can film all by itself. But will Jonathan get his camera back? Next, he joins an experienced cave diver to explore a famous underwater cave in Northern Florida (USA).

Cave diving is the most difficult and dangerous type of diving, so the training to become a certified cave diver is arduous. This episode documents Jonathan's actual cave training in the Bahamas and follows him as he learns how to dive safely in the overhead environment of a cave in an attempt to earn his full cave diver certification.

Deep in the heart of Mexico's Yucatan, Jonathan is exploring remote cenotes in the jungle that were once used for Mayan rituals. Just reaching the surface of the water requires rappelling down from the forest above. But then, beneath the surface, he encounters strange alien life forms that live in total darkness, and the remains of humans and animal sacrifices from an ancient culture.

In the Flower Garden Banks National Marine Sanctuary, Jonathan investigates some of the densest coral reefs in the Caribbean as they spawn under cover of darkness. Then he heads over to Silver Springs for the Sea Hunt Forever Festival, celebrating the classic TV show Sea Hunt and the vintage scuba gear that was used on the program.

Jonathan heads down to the shipwrecks of North Carolina (USA) to observe how these wrecks have become home to thousands of animals, including Sand Tiger sharks. But instead of chasing all the fish, the sharks are protecting many of them! Then, Jonathan visits the School for Field Studies in the Turks & Caicos Islands to learn how college students conduct fieldwork.

In a shark-filled adventure, Jonathan travels to the Bahamas to meet Neal Harvey, a world-renown shark handler who will attempt to teach Jonathan how to put Caribbean Reef sharks into a relaxed state known as tonic immobility! Then, Jonathan heads to NASA's Neutral Buoyancy Lab in Houston, Texas (USA), where astronauts train for space walking underwater.

In this epic octopus adventure, Jonathan visits two aquaria to learn about the Giant Pacific octopus, and then travels to Seattle, Washington (USA) to join the Seattle Aquarium dive team on an octopus survey. He meets the Giant Pacific Octopus, the world's largest octopus, and discovers how clever this huge invertebrate really is!

Jonathan joins shark researcher Dr. Stephen Kajiura to test how well wild sharks can detect electrical fields in their environment. Then, he heads to New Jersey (USA) to learn how to dive in the Mark V commercial diving helmet! Finally, he ends up in the Gulf of Mexico to learn how oil platforms can actually become a healthy artificial reef and attract marine life from miles around.
