Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms). How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it? Join us for an overview of the ANDRILL (ANtarctic geological DRILLing) Project, a multinational collaboration among 200-plus scientists, students, and educators from five nations, to recover sediment cores (layered sections of earth) from under the Antarctic ice and seas. Nadine, a glaciology graduate student from UC Santa Cruz, spent four weeks on the West Antarctic Ice Sheet investigating ice sheets and global climate change. Dr. Tulaczyk, a glaciologist from UC Santa Cruz, studies the lakes, floods, and ice quakes that occur under the giant glaciers of Antarctica. He is among only 200 scientists world-wide who study ice sheet dynamics and its role in climate change. Pulling food to prepare for four weeks at the West Antarctic Ice Sheet camp. Craig George and Glenn Sheehan explain how scientists have learned from Iñupiaq hunters to make more accurate counts of bowhead whales. Daniel Lum talks about the changes in ocean ice near Barrow. 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.
