  • No Fish Left Uncounted
    Saturday, January 25
    3:30 pm on UEN-TV 9.1
    How do you count two fish, three fish or even a school of fish? In Dry Tortugas National Park, located 70 miles from Key West, Florida, a group of scientists have joined forces to conduct a massive fish census. In this unprecedented collaboration, experts from four different agencies unite to count and analyze fish data from select sites. Changing Seas follows highly-skilled science divers as they determine the size of fish populations in hopes of better understanding how fishing pressures and environmental changes affect populations of marine resources within the park.
  • Sentinels of the Seas
    Saturday, February 1
    3:30 pm on UEN-TV 9.1
    Bottlenose dolphins are a beloved Florida icon. But, recent studies show disturbing signs of immune system dysfunction and disease plaguing this charismatic mammal. These problems might be linked to legacy contaminants and other pollutants which bio-accumulate up the ocean food chain. Changing Seas meets with experts for an in-depth look at the health status of Florida's wild bottlenose dolphins.
  • Seagrasses and Mangroves
    Saturday, February 8
    3:30 pm on UEN-TV 9.1
    They are an ancient species of flowering plants that grow submerged in all of the world's oceans. Seagrasses link offshore coral reefs with coastal mangrove forests. Today, these "prairies of the sea," along with mangroves, are on the decline globally. Scientists fear the diminishing vegetation could result in an ecosystem collapse from the bottom of the food chain all the way to the top. Changing Seas joins experts in the field as they work to restore Florida's important mangroves and seagrasses.
  • Sinking The Vandenberg
    Saturday, February 15
    3:30 pm on UEN-TV 9.1
    In the turquoise blue waters of the Florida Keys, a new attraction is drawing scuba divers from around the world: The USNS General Hoyt S. Vandenberg. Laid to rest in the Florida Keys National Marine Sanctuary, the Vandenberg is the world's second largest intentionally sunk shipwreck. In her last mission as an artificial reef, this massive ship is already attracting a variety of fish and other marine life. Now, natural resources managers are trying to determine what impact this artificial reef has on fish populations and the health of the surrounding natural reefs.
  • Coral Hybrids
    Saturday, February 22
    3:30 pm on UEN-TV 9.1
    While Elkhorn and Staghorn corals have undergone a drastic decline in the Caribbean, their hybrid, "Fused Staghorn," is increasing in numbers in parts of the region. One scientist is studying the animals in Belize to see if the hybrid might be better equipped to deal with environmental stressors than its parents.
  • Sunken Stories
    Saturday, March 1
    3:30 pm on UEN-TV 9.1
    In the Florida Keys, divers from around the country learn how to map shipwrecks and apply their skills on a mysterious 19th Century slave ship. When diving isn't possible, professional explorers use high-tech tools to scan objects buried beneath the seafloor.
  • Creatures of the Deep
    Saturday, March 8
    3:30 pm on UEN-TV 9.1
    Little-known animals spend their entire lives in the Gulf of Mexico's cold, deep waters. New research sheds light on the lives of these mysterious creatures of the deep.
  • Reefs of Rangiroa
    Saturday, March 15
    3:30 pm on UEN-TV 9.1
    The Changing Seasteam meets with researchers in French Polynesia, where scientists conduct extensive habitat mapping to create a one-of-a-kind sea floor atlas. Experts also assess the health of the reefs to compare and contrast human impacts on reef systems over a large geographical area.
