Kathryn Johnson, an electrical engineer at the Colorado School of Mines, studies large utility-scale wind turbines. Kathryn’s research aims to make the turbines more efficient in order to capture as much of the wind’s energy as possible. Viewers also visit NSF’s National Center for Atmospheric Research, where scientists are working with local utility companies to create an advanced wind energy prediction system. Using data from sensors mounted on each turbine, the system generates a forecast specific to each turbine on a wind farm. This helps the utility company provide as much energy as possible from clean sources.

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.
Students explore the important role the environment plays in everyday life. Several environmental problems are highlighted, with a focus on pollution and global warming. Additional concepts and terminology discussed include ecology, biological extinction, resource depletion, overconsumption of resources, fossil fuels, global climate change, and natural resources.
As shown on the History Channel. The Sierra Nevada, North America's highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley. Walled by sheer 3,000-foot granite cliffs and made from one of the toughest rocks on earth, it is home to the mighty El Capitan and iconic Half Dome. Yet how this extraordinary valley formed has been the subject of controversy for over 100 years. Was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?
Nestled deep inside the Siskiyou Mountains, the caves formed as rainwater from the ancient forest above dissolved the surrounding marble and created one of the world's few marble caves. The highly complex geology found on the Monument contributes to the unusual and rare plants and animals found nowhere else but here. The cave geology is combined with the diversity of plants and animals to tell a unique story of the Pacific Northwest.
Powerful forces have forged the conditions on Earth that have made life possible. The millennia have been witnesses to the formation of the planet: its singular position in relation to the sun, the evolution of the continents, and the birth of entire mountain chains. All of these elements combine to create Earth’s constantly changing climate. Homo sapiens emerge into this unpredictable and violent world, fighting for survival from the start. It is these early humans’ ability to adapt that allows them to triumph even in the face of incredible adversity and sets the path for modern man. Part of the "How Climate Made History" series.
Volcanoes are a part of the earth, and they have intrigued people for hundreds of years. Scientists study the earth's plates in order to understand the complexity of volcanic activity around the world. They also study different types of lava, rocks, and the gases that have dissolved into rocks. In the past, studying volcanic activity was extremely dangerous for scientists. Now they have access to tools, such as global positioning systems and seismometers, to help in predicting volcanic activity.
Humans construct boundaries around homes, neighborhoods, and nations to bring order to a chaotic world. However, they rarely consider how these boundaries affect the environment or others. Photographer Krista Schlyer and biologist Jon Beckman study how fabricated barriers influence the movement of wildlife. Schlyer and Beckmann have seen the damaging impacts resulting from the wall built along the Mexico-United States border. Humans probably will not stop constructing walls and fences any time soon, but planning the boundaries with wildlife in mind can help prevent these structures from causing environmental harm. Part of the "Think Like a Scientist" series.
Geologist John Goodge looks for clues about Antarctica's past in the two percent of the continent that is not covered in ice. The University of Minnesota, Duluth professor studies rocks that help provide evidence about how this desolate continent has formed and changed over time. In late 2010 and early 2011, he spent several weeks in the field with other scientists, visiting a dozen sites in Antarctica, along 1200 miles of mountains. They collected 2500 pounds of rocks, which are now being analyzed back in the states.
The Nakanai Mountains of Papua New Guinea are a remote part of the world, rarely seen by outsiders. Wild Chronicles joins National Geographic Young Explorers grantee Trip Jennings and a team of explorers as they embark on the first known kayaking expedition down the Pandi River from its underground source to the sea. But they must travel through dense jungle and uncharted caves before they can document the islands stunning landscape in hopes of protecting the area for the future. Segment of video from Wild Chronicles Series.
Canada's coastal forest is part of an ancient forest system of redwood, spruce, and cedar trees. It is also home to some of the largest aggregations of top predators in North America. The trees of this forest are huge, and forest productivity here rivals even some of the world's biggest tropical rain forests. Part of the "Nature's Microworlds" series.
The first in a series of five documentaries plots the course of the river, from its source to its delta. In a succession of spectacular images we see the extraordinary geographical route that the Mekong takes, from the Tibetan plateau, down the mountains of the Yunnan Province in China, then through the tropical valleys and virgin forests of Burma, Cambodia, Laos and Thailand before reaching the green plains of Vietnam. In the tropical forest, nature abounds with wild animal species, rare plants and flowers. In Laos', whole villages still pray to the Gods of Trees while in Thailand a hunter shows how the hunting of Asian elephants for preservation, now forbidden, was practiced. Series: The Soul of Southeast Asia
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, intrigued by the name given to the mountains, "the hills of the round earth," Moko sets off to find out if the earth is really round. An old man tells him if he keeps walking straight, he could travel round the earth and get back to his starting point. Moko follows his advice but since he never got the feeling he was walking around a sphere, he still thinks the earth is flat.

Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, having made their way beyond the great valley, Moko and Totemie discover a blanket of white stretching out in front of them. An old man tells them that once they get to the other side they will see what so many others have dreamt of seeing, but that they must fly like birds. He offers them a strange kite. As the wind picks up, they hang on tight and fly off from the salt pan.

Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, continuing their expedition, Moko and Totemie come across a great river. It is so beautiful and so wide that they decide to build a raft and explore it further. A woman who is returning from the fields warns them of a great danger, but it is too late, the current has already carried the raft along its waves. In the distance they can hear a deep rumbling sound, and it seems to be getting closer. As their raft is propelled forward, it is stopped by the edge of a reef just on the edge of a great chasm. The spectacle is so breathtaking that they forget their fear. When they finally manage to reach the shore safely, they thank the river for having kept them safe and having shown them the magnificent view of the waterfall.
