Forage Fish, Wild Olympics, Biofuel from Cornfield Residue, Fire Ants (#401) Duration: 26:46 STEREO TVG

Researchers on the Oregon coast study the role that forage fish play in the food chain. Sometimes called "bait fish", sardines, anchovies, smelt and other small fish are vitally important in sustaining larger species - including sea birds, salmon, and marine mammals like sea lions. Humans also catch forage fish, mainly for animal feed, and there's growing concern that large-scale commercial harvesting of forage fish comes at the expense of other marine life, potentially with catastrophic results. Spectacular Olympic National Park is the centerpiece of the verdant Olympic Peninsula in northwest Washington State, right up against the Canadian border. There's now a bill in Congress that would add more protection to the forests and watersheds around the park, and we explore why there's wide support for the proposal among the people living there. In another report on emerging second-generation biofuels, we travel to Iowa where farmers are discovering there's growing demand for the residue in their cornfields - stalks, leaves, husks and cobs - left on the ground after the corn is harvested, That residue, called "corn stover", is biomass that can also be converted into ethanol. Everybody wants to eradicate biting, invasive fire ants, but scientists say they can learn a great deal by studying the social structure of these insects. New research shows that the widespread success of fire ants has been assisted when humans disturb natural areas with roads and development.

Owyhee Canyonlands, Sustainable Alaskan Village, Algae Power, Fungi Fuel (#402) Duration: 26:46 STEREO TVG

Much of Oregon is a desert; and in the dry, remote southeastern corner of the state there's a wild and captivating canyon landscape carved by the Owyhee River. It's been described as the largest intact, unprotected stretch of the American West, but it needs more protection from development pressure, including mining. A robust campaign for wilderness designation is making progress. We travel to a remote Alaskan village, Igiugig, where young native Alaskans are adopting new technologies and green ethics to build a healthy, sustainable future while keeping true to their traditions. With another report on emerging biofuels, we learn about new advances in converting algae into a wide range of useful products, including oil, growing the algae with by-products from corn ethanol distilleries. We meet a scientist in Montana who searches the globe for botanical specimens, discovering fungi and bacteria in the tissues of some plants that can be converted into a diesel-like fuel.

Wilderness Anniversary, Arkansas Oil Pipeline, Climbing Fish (#403) Duration: 26:46 STEREO TVG

Marking the fiftieth anniversary of the Wilderness Act, we explore its origins and success in protecting more than 100 million acres of unspoiled natural wilderness, a distinctly American achievement. There are still many more areas of wild nature that deserve protection, and the Wilderness Act remains an essential law in the cause of conservation. In March, 2013, a rupture in a buried oil pipeline surprised suburban homeowners in Mayflower, Arkansas by flooding their streets with crude oil. Many of them didn't even know there was a pipeline under their yards. To find out more about this event, we offer a two-part investigative story co-produced with Inside Climate News, a Pulitzer Prize-winning reporting unit. Researchers study a type of Goby fish in Hawaii that climbs up steep waterfalls to reach its freshwater spawning areas, an amazing story of adaptation and evolution over time.

Seamount of Life. Arctic Traffic, Altamaha River Pollution, Diatoms and Climate Change (#404) Duration: 26:46 STEREO TVG

Using special recording technology to document the spawning of endangered fish like the Nassau grouper, scientists in the Caribbean study spawning aggregation sites that are critically important for the survival of many ocean species. We follow them to one of these sites off the western coast of Puerto Rico that has been severely impacted by overfishing; conservationists say an effectively enforced marine protected area is urgently needed there. Climate change is causing a rapid loss of summer sea ice in the Arctic Ocean, opening the region to more shipping traffic, oil exploration and other industrial activities that were never possible before. This is creating growing risks to whales, walruses, seals and seabirds - especially in the narrow migration corridor in the Bering Strait. The traffic also poses new risks to the region's local native people who hunt and fish in small boats. Conservationists are pressing for new measures to protect the marine environment, wildlife and welfare of local residents in the changing Arctic. The Altamaha River in southern Georgia is a major waterway, still undammed, flowing in its natural state more than a hundred miles to the Atlantic and its spectacular estuary. But there's a large pulp mill on the river that has been operating for decades, and critics say it has been discharging pollution into the river which they allege the pulp company refuses to clean up, and which the state of Georgia has been slow to address. We go to the river to see for ourselves. In another story on the warming Arctic, we meet researchers in Greenland who gather samples of fossilized microscopic algae in lake sediments, discovering vital clues about past and current climate change in the region.

Fish Lifts for River Herring, Biofuel Start-ups, Fabulous Fungi, Prickly Pear Cactus for Clean Water (#405) Duration: 26:46 STEREO TVG

Every spring, on the Saugatucket River in Rhode Island, tens of thousands of river herring try to swim upriver from the Atlantic to spawn, facing dams on the river that block their way. Many fish find it too exhausting to use fish ladders on the dams, and they give up their struggle. But happily there are people who volunteer to help the fish on their journey, using buckets in an effort called a "fish lift" to get the herring over the dams. We look at the new frontier in renewable sources of energy - sources grown as agricultural crops. New biofuel enterprises based on switchgrass, corn stover and wood waste are still in the start-up stage, trying to develop their technologies, scale up their production, and secure a market for their ethanol product with some controversial government support. Living on the San Juan Islands off the coast of Washington State means being conscious about protecting the land, water, and wildlife High school students on Orca Island are keeping their water clean with some help from Mother Nature. Our Science Nation report takes us to a lab where researchers are testing a Mexican folk recipe: using the "goo" inside prickly pear cactus to purify water contaminated by chemicals or oil spills.

    • KQED DT9s Over the Air: beginning Wed 7/09

      (DT9.1, 9.2, 9.3) The PSIP Info part of our Over the Air (OTA) signal for KQED DT9.1, 9.2, 9.3 dropped out of our overall signal early Wednesday 7/09. Once PSIP was restored most OTA receivers moved our signal back to the correct channel locations. However, for some viewers, it appears as if they have lost […]

    • KQED FM 88.1 translator off air Tues 6/03

      The Martinez translator for KQED-FM will be off the air all day Tuesday June 3rd. We are rebuilding the 25 year old site with all new antennas and cabling. This should only affect people listening on 88.1MHz in the Martinez/Benicia area.

    • KQET planned overnight outage: early Tues 5/13

      (DT25.1, 25.2, 25.3) KQET’s Over The Air (OTA) signal will shut down late May 12/early Tues 5/13 shortly after midnight to allow for extensive electrical maintenance work at the transmitter. Engineers will do their best to complete the work by 6am Tuesday morning. This will affect OTA viewers of the DT25 channels, and signal providers […]
