Sea star wasting syndrome is the largest marine disease event ever seen. Microbiologist Ian Hewson shares what inspires him to study oceanic ecosystems, and how scientists from Cornell University are solving this ecological mystery.
Part of the "Branches on the Tree of Life" series. Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Covers phylum characteristics and key biological details for five classes: sea stars, brittle stars and basket stars, sea urchins and sand dollars (including developmental stages), sea cucumbers, and crinoids (feather stars).
How could a body of water as big as the Mediterranean Sea just disappear? It would take decades and more than a 1,000 research studies to even start to figure out all the possible causes of one of the greatest vanishing acts in Earth’s history. Part of the "Eons" series.
Hurricane season runs from June to November. During these months, all three requirements for hurricanes to form are present. Storms form off the coast of Africa and travel on currents of warm ocean water. Also, the wind patterns alter the location of the jet stream. Part of the "Seasonal Science" series.
Communication between people and cultures initially stemmed from trade and commerce. With Guttenberg's invention of the printing press, information was available to people beyond the elite and wealthy for the first time. Trade drew explorers out into the oceans, and mapmakers outlined their treacherous journeys. These basic maps are what led Columbus to believe he could reach the East by sailing west. Instead he found America, and established trade routes between America and Europe.
Astrophysicists at the American Museum of Natural History are searching through early photographs of the night sky in an effort to digitize the collection of photographs. Also in this episode, they discuss the advancement of astronomical instrumentation through the ages. Part of the "Shelf Life" series.
Investigates the physical features of a number of "ugly" animals to demonstrate the efficiency of their odd appendages or disproportionate body parts. Studies the nose of the star-nosed mole, the fleshy protuberances in the mouth of the snapping turtle, the warthog's warts and tusks, the vulture's head, the northern elephant seal's proboscis, the proboscis monkey's nose and protruding stomach, the naked mole rat's lack of hair or fur, the whip scorpion's alien appearance, the mouths of deep sea denizens, and the bat's head.
Gravity is the most powerful and exacting force in the universe. It binds us together, its reach hangs stars in the sky and its grip crushes light. Without gravity, stars, comets, moons, nebulae, and even the Earth itself would not exist. Explore how science and humanity discovered, overcame, and utilized gravity. Learn what it takes to propel objects into the heavens, to ride a wave, or to ski down a slope. Take a front row seat as an astronaut subjects himself to the weightless wonders of the specially modified aircraft used to train astronauts known as the "Vomit Comet."
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, on this morning, Moko is rowing relentlessly to bring back the barge as Mei-Lei sleeps. Suddenly the current shirts, he can't seem to make the oar move at all. He wakes Mei-Lei so she can help him row, but it is no use, the barge starts moving in the opposite direction. In the distance they notice a fisherman and try to call out to him, but he is too far and cannot hear them. Beyond a huge boulder they see a forest and start rowing furiously in its direction. Finally ashore, Moko and Mei-Lei think that the sea still had another secret in store for them, this new part of Mei-Lei's island.
Glaciers are melting, sea levels are rising, and the weather is becoming more extreme. Corporations talk about optimizing resource use, saving energy and reducing greenhouse gas emissions to stop worsening climate change. They start to promote hybrid cars, plant-based detergents and new technologies… but how much do they really intend to change, and what do plants have to do with marketing?
Host Jessica Robertson travels across North and South Carolina to gather questions about climate change. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
It is Fletcher's first autumn, and he is alarmed when the leaves on his favorite tree start to turn brown and fall off. He tries day after day to save the leaves that the tree is losing to the wind. When the tree has no leaves left, Fletcher goes to bed in despair. However, after a cold night, Fletcher wakes up to see his tree sparkling as he has never seen it before. Based on the children's book by Julia Rawlinson.
A young boy and his dog decide they have had enough of winter, so they plant a garden. They watch and wait until all the brown starts to become a hopeful shade of green, a sign that spring may finally be on its way. Based on the book by Erin Stead.
Parakeet talks about how sad and difficult it is when friends leave. The llama explains she is worried because the jaguar prefers to starve to death than to cross the river and search for food. The jaguar explains his fear: his brother drowned while crossing the river. Amanda feels the world is collapsing on her, she thought only the old died. The fleas show their documentary on death, the cycle of life, and the importance of mourning when someone you know dies. Talks about Celia Cruz's death, the grief her husband, friends, and fans experienced, and how she lives on through her work and music.
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, Moko and Mei-Lei are gathering seashells in between the rocks on the white sand beach to decorate the village's houses. Moko asks Mei-Lei if they can go to other beaches to try to find other shells. Mei-Lei likes the idea and goes to ask a fisherman to take them to another beach on his boat. Just beyond the village Moko sees a vast plain that has been flooded with water. He thinks this must have been the great wave, flooding the field with water so that the rice would grow. This is when Mei-Lei picks up a magnificent seashell and Moko believes that it must surely be a gift from the ocean. Moko and Mei-Lei make their way back home, carrying their gift and happy to have seen wonderful new places. They are certain that the ocean must know an underground passage in which it sends waves every now and then to feed the rivers and the fields.
A manatee turns up in Trinity Bay near Galveston, Texas. He is named Trinidad, but several rescue groups must work to save him when the water temperature drops. Then, two sea lions in San Diego have life-threatening entanglements around their necks, so the SeaWorld team steps in to save them. Part of the Sea Rescue series.
