B-Roll for playback during webcast, "Tundra and Climate Change with Steve Hastings," on 5/24/08. Footage includes shots of data gathering, facilities and landscape at the Barrow Environmental Observatory. The Jakobshavn Isbrae is among the fastest-moving glaciers in the world. The Jakobshavn is an outlet glacier, one of the few places where the giant Greenland ice sheet can shed ice in the form of gigantic icebergs. This timelapse video by Jason Amundson of the University of Alaska Fairbanks shows one of these massive calving events. Notice the dark blue ice that surfaces when the iceberg flips over in the ice-choked Ilulissat icefjord. The South Pole Telescope captured its first light on Feb. 16, 2007! Join Exploratorium host Mary Miller as she talks with scientists at the South Pole and finds out more about life at the Pole. Mary Miller chats with scientists at the South Pole about the nearly-completed telescope. The satellite connection to the pole deteriorated quickly, and we hope to repeat this program in the near future. Stay tuned for updates! Check out this amazing footage of how scientists drop detectors miles into the ice to search for elusive neutrinos. What's Christmas like at the South Pole? Also learn about the Race Around the World and the installation of the telescope's new receiver. Join us as we talk to scientists from the ANDRILL (ANtarctica DRILLing) project, who are currently on a geological drilling expedition in Antarctica. Tom Crawford and Jeff McMahon show us a day in the life of a South Pole scientist, then talk about what the telescope will be searching for: dark matter, galaxy clusters, and evidence of the universe expanding. South Pole scientists Tom Crawford and Jeff McMahon take us on a virtual tour of the South Pole Station, then discuss working in the polar environment. After years of preparation, scientists from the University of Chicago are making the long journey to the South Pole to begin construction on the new 10-meter telescope. Join us as we talk to scientists at the pole about their long journey, learn about the pre-building of the telescope in Texas last summer; and find out what challenges they face in constructing a major scientific instrument in freezing conditions.
