An interview with Mel Zucker, Professor of Geology, Skyline College, San Bruno, California.
In the early 1900s, German meteorologist Alfred Wegener suggested that the earth's continents were once a single landmass that had somehow split into pieces, drifting their separate ways. Geologists the world over called his idea preposterous. Decades later, their ridicule shifted to admiration as new tools developed by the military to map the ocean floors revealed the engine that drives the continents' movement. Geology professor Mel Zucker tells the story of this brilliant earth scientist and how, long after his death, science finally caught up with Wegener's crazy idea.
Landings and take-offs of helicopters, a twin otter airplane, a LC-130 Hercules transport plane; and a shot of a Hagglund tracked vehicle. Transportation used in Greenland to do scientific research. Scenery of Ilulissat from a boat, the Katak. The Mars Phoenix Lander will have been collecting data and sending it back to earth for a month! Exploratorium Senior Scientist Paul Doherty will examine the data and tell us what new information we've gained about Mars. We'll also get an update on our old friends, the Mars rovers Spirit and Opportunity!
Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems. Join us as we celebrate the beginning of summer in the Arctic and the long, cold winter in Antarctica. We'll connect live to two polar field sites: Summit Camp atop Greenland's vast ice sheet, where the sun will be shining 24 hours a day, and the South Pole Research Station, now in the middle of 6 months of darkness.
Dr. Jewel Bennett, an endangered species biologist with the US Fish and Wildlife Service's Fairbanks field office, is in Barrow leading a survey team tracking the endangered Steller's and Spectacled Eiders' populations. Inupiaq elders, local experts and scientific researchers partner on the North Slope to study and understand the changing environment. Wendy Eisner and Chris Cuomo join us to talk about their project: Indigenous Knowledge and Landscape in Northern Alaska. Amanda Grannas' research group at Villanova University studies a wide range of topics under the umbrella of "analytical environmental chemistry", including the impacts of pollutants in the snow and ice. We'll chat with Amanda about her current research in the Arctic. Join us for this special Webcast from Summit Camp, which sits atop nearly 2 miles (about 3200 m) of ice on the Greenland ice cap. We'll talk with Zoe Courville, an Ice Stories blogger and snow researcher from the Cold Regions Research and Engineering Lab, about life on top of an ice sheet. She'll also discuss her research into how snow becomes glaciers.
