  • 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.

  • 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.
