Host Steve Backshall examines what is by far the largest ecosystem on the planet: the deep sea. It contains some of the most extraordinary and bizarre life forms. There is even life on the deep seabed, where armies of sea urchins, giant wood louse, and deep sea crabs feed from a thick layer of sediment. Part of the "Nature's Microworlds" series.

Explores the fascinating features of the animal kingdom. The taxonomy of the different invertebrate and vertebrate phyla are the focus of the program, with special emphasis placed on the evolutionary relationships of the various phyla. Each of the major phyla are discussed, going from simple to more complex organisms. Other terminology includes: sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, arthropods, echinoderms, fishes, amphibians, reptiles, birds, and mammals.
A community of sea lions annually visits an island in the Gulf of California, where the babies are born and must be taught to swim. Compares seals and sea lions. Details physical characteristics, diet, behaviors, and enemies. The only enemy this "grizzly bear of the sea" cannot fight is fishing boats.
Join vulcanologists as they venture into the heart of Ethiopia's Erta Ale, the oldest live volcano in the world, to ply its secrets of creation. Their mission to sample molten rock from the lava lake requires hauling more than 1000 pounds of gear to the crater, and then rappelling into the active cone. Blistering heat and sulfur stench greet them as they battle this formidable boiling mountain for the sake of science. Segment of video from Wild Chronicles Series.
The gray whale has survived the threat of extinction throughout the nineteenth and twentieth centuries. Today, these wonderful giants find refuge in the lagoons of Ojo de Liebre and San Ignacio. These sanctuaries also promote responsible tourism and sustainable fishing methods. Part of the "Bios: Nature and Society" series.
Smalltooth sawfish have been around for over 50 million years, but today they are threatened. Its toothed rostrum can easily become entangled in fishing lines, but anglers are learning how to handle them for a safe release. Part of the "Endangered Ocean" series.
Anything people use every day can become marine debris if its is not disposed of properly, and the most common items found during shoreline cleanups are plastics. Sometimes the debris is so tiny that it can barely be seen in the water. Marine debris is more than just trash in the ocean. Part of the "Trash Talk" series.
Maritime archaeology is a discipline within archaeology that specifically studies human interaction with oceans, lakes, and rivers through the study of artifacts. Researchers trace the historical aspects of human dependence and influences on bodies of water. Some areas of interest include harvested goods from the sea, fishing techniques, transportation, and water quality. Part of the "Adventures of a Maritime Archaeologist" series.
Currents in the Pacific Ocean have brought derelict fishing nets and gear to the waters around the Hawaiian islands. These nets are a safety hazard to ships and cause extensive damage to the ecosystem by snagging on coral reefs, entangling wildlife, and polluting shorelines. Instead of adding these nets to already congested landfills, Hawaii’s multi-partner marine debris group came up with a unique program to downcycle this marine debris into usable electricity.
Ocean “dead zones” along the Washington and Oregon coasts are threatening critical U.S. fishing areas. These oxygen-depleted regions, that loose virtually all of their marine life in the summer, are expanding, and new ones are appearing in the Pacific Ocean. With support from the National Science Foundation, Oceanographer Jack Bath is also using an impressive new tool, an unmanned underwater glider that provides round the clock monitoring of these zones.
African penguins are critically endangered. Their colonies have been reduced by 70 percent in the last decade. Commercial fishing is a great factor in the penguins' population decline as the world's oceans are being overfished. With penguin chicks’ growth and health in crisis, a hands-on rescue strategy could sustain struggling colonies while conservationists work to ensure the species’ survival.
Curiosity Quest Goes Green host Joel Greene visits the sea turtle hospital in Marathon, Florida to meet the staff who has dedicated their lives to rescuing, rehabbing, and releasing sea turtles back into the wild. Some turtles get hit by boats, some swallow fishing hooks, some have tumors, but all of these amazing creatures can be treated at this hospital. Hopefully they heal quickly and return back to their natural habitat. Part of the Curiosity Quest Series.
The fifth in a series of five documentaries looks at the future of the Greater Mekong by understanding its historical perspective and new technological advances. This title traces the first men living from gathering, hunting and fishing to new technologies and Western influences that threaten to change their way of life. Interviewers also meet with young people and educators in charge of preparing, educating and training for the future preservation of the river. Series: The Soul of Southeast Asia
The people of the Cook Islands have created one of the world’s largest marine parks, and now they are working together to figure out what that means to a bevy of conflicting interests, from fishermen to miners. The scientists lend their expertise and help the residents map their resources. Part of the "Global Reef Expedition" series.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
Everywhere one looks in Southern Louisiana there's water: rivers, bayous, swamps, the Mississippi River, and the Gulf of Mexico. And everyone in Cajun Country has a water story, or two or three or more. Its waterways support the biggest economies in Louisiana - a $70 billion a year oil and gas industry, a $2.4 billion a year fishing business, tourism and recreational sports. But these waterways are also home to some insidious polluters along a 100-mile-long stretch of the Mississippi known "Cancer Alley," the world's largest Dead Zone in the Gulf of Mexico and erosion that is costing the coastline twenty five square miles of wetlands a year.
On a distant island near Borneo, Din keeps an incredible secret. He has forged a friendship with one of the rarest and shyest creatures in the ocean, a dugong-cousin to the manatee. Through their adventures, Din uncovers the mysterious behavior of dugongs and explores the natural diversity of his island home. The story also exposes the plight of the islanders, as the arrival of foreign fishermen threatens their island.
What happens to the size and health of ducklings if their mothers have to leave the nests for long periods of time to get food? That’s what Bill Hopkins, a fisheries and wildlife professor, hopes to find out, with support from the National Science Foundation. Hopkins’ research team at Virginia Tech, including wildlife Ph.D. student Sarah DuRant, is studying how environmental factors influence hatchlings, incubation, and overall survival of wild ducks.
Fishermen from Rhode Island to Maine are beginning to farm mussels in socks in the ocean. First, they collect baby mussel seed on ropes near the shore. The seed goes into a sock around a long rope. On the water, the sock with the rope is connected to buoys, dropped into the water, and left to grow in the ocean for at least a year. After one year, juicy mussels are bursting through the socks.
Bay Mouth Bar holds what is reputed to be the largest diversity of predatory snails in the world. Dr. David Kimbro is investigating how top predators in this group of seagrass beds affect the system as a whole, which in turn affects local fisheries. Part of the series "In The Grass, On The Reef."
