At the National Ice Core Lab in Denver, Colorado, scientists study ice cores in a Class 100 clean room lab kept at minus 7 degrees F. The Jakobshavn Isbræ 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 (100x real speed) from glaciologist Mark Fahnestock 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. Time interval on this timelapse is 10 seconds per frame. A tattoo lasts a lifetime, thanks to your white blood cells. Watch and listen as researcher Mike McGrath explains how these warrior cells protect you from disease—and keep body art intact. What's so special about the sea urchin? Watch and listen as urchin researcher Fred Wilt describes the things he and others observe under the microscope. In this video, ride in a special Mattracks truck across the ice sheet with geologist Christina Riesselman as she travels with ANDRILL Staff Scientist Richard Levy from McMurdo Station to the ANDRILL drill site. They investigate the truck’s special wheels, observe beautiful panoramas of the Transantarctic Mountains, and hear the drill running at the drill site. Join us for more conversation with David Ainley and other researchers studying Adelie penguins in Antarctica’s Ross Sea. This machinima, a movie made entirely within Second Life (a 3-D virtual world), shows a simulation of the impact of a meteor on the surface of Mars. Join Exploratorium Senior Scientist Paul Doherty as he gives us an update on Mars and examines the possibility of an upcoming asteroid collision with the red planet! Scientist working on the South Pole Telescope explain data collection, focusing on the telescope's receiver, a precise instrument with a thousand "eyes" pointed to the distant universe. Glaciologist and Ice Stories correspondent Nadine Quintana Krupinski gives us a brief tour of her deep field camp on the West Antarctic Ice Sheet.
