Changing Seas
Changing Seas is a public television series produced by WPBT2 in Miami, Florida. Narrated by well-known voice talent Peter Thomas, this series takes viewers on an exciting adventure to the heart of our liquid planet. The oceans cover roughly 70 percent of the earth's surface and they contain 97 percent of the world's water supply. Nevertheless, only five percent of their vast expanse has been explored - leaving in secret a deep, liquid wilderness yet to be discovered. Regardless, the oceans have long played an important role in people's lives. Currently, more than half of all Americans live within 50 miles of the coast, and that number is rising. It is estimated that by 2025 more than 75 percent of Americans will live along the country's shorelines. Coastal and marine waters support 28 million jobs and draw 189 million tourists a year. While the population's dependence on the oceans as a natural resource and a source for recreation continues to increase, the health of these large bodies of water is rapidly declining. Over-fishing, global climate change, pollution: these are only a few of the threats that the oceans are facing today. At the same time, the seas hold great promise for ongoing medical research, as an untapped source of alternate energy, and other benefits that scientists are just now beginning to discover. Changing Seas goes to sea with explorers and scientists as they uncover new information that could lead to scientific breakthroughs. This documentary series lets viewers experience first-hand how oceanographers and other experts study earth's last frontier, and it sheds light on how human activities are threatening ocean resources.

Episode 1
Alien Invaders
Tue, Jun 7, 2011
In the waters of the western Atlantic and Caribbean, a voracious alien predator has taken hold. Native to the Indo-Pacific, the invasive lionfish is a major threat to biodiversity and the health of already stressed coral reef ecosystems. The popular aquarium fish is thought to have first been released into the wild in South Florida in the mid 1980s. With no natural predator in this part of the world, lionfish numbers have increased rapidly. Experts say that on some Bahamian reefs lionfish have reduced native fish populations by up to 90 percent in just a few years. To combat this problem, experts are encouraging people to "eat'em to beat'em". Changing Seas joins scientists in the field to learn more about this beautiful, yet gluttonous feeder and the threat it is posing to native fish populations.
Episode 2
Reef Revival
Tue, Jun 14, 2011
In the emerging science of coral reef restoration, marine biologists and resource managers are discovering naturally occurring mechanisms that promote coral growth and restore ecological balance in these gardens of the sea. Since the late 1970s close to 98% of Staghorn and Elkhorn corals have disappeared from reefs in Florida and the Caribbean. Around the world, damage from boat groundings and other factors have placed these organisms on the "threatened" list of the Endangered Species Act. Staghorn and Elkhorn are considered principal reef building corals. In South Florida, scientists are using native sponges and spiny sea urchins in novel ways that may help attract corals to damaged sites. Can nature heal itself with a little help from marine experts? Can new technologies help restore the lost coral communities?
Episode 3
Prescription: Oceans
Tue, Jun 21, 2011
The oceans are part of America's newest medical frontier. In Florida, scientists are studying a variety of marine invertebrates which may hold the key to unlocking the secrets of our own biology. At Harbor Branch Oceanographic Institute in Fort Pierce, researchers are testing sea sponges for their potential anti-cancer properties. At The Whitney Laboratory for Marine Bioscience in Marineland, experts are taking a closer look at horseshoe crabs to better understand how eyes function and change with age. Scientists there are also studying sea slugs for insights into neurodegenerative disorders such as Alzheimer's and Parkinson's disease. What clues will these and other simple organisms reveal about the human body? Are there cures that lie beneath the waves?
Episode 4
After the Spill
Tue, Jun 28, 2011
The catastrophic oil spill in the Gulf of Mexico in April 2010 may no longer make headline news, but the story is far from over. Oceanographers continue to study the long-term effects this disaster might have on marine ecosystems. Among them are the scientists from the College of Marine Science at the University of South Florida, who have been studying the impacts of this spill from the beginning. Experts are analyzing water and sediment samples for hydrocarbon presence and toxicity and are studying the long-term effects the spill might have on a number of marine species. What impacts will low-level, chronic toxicity from oil and dispersants have on the environment? How long until the true extent of this disaster will be known?
