The Exploratorium's remote crew has landed in Barrow, AK, to showcase the vast array of science being conducted at this northernmost tip of the continent. Join us for this introduction to Barrow: where is it? why are so many scientists here? why are May and June such important times? 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. 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. Glaciologist and Ice Stories correspondent Nadine Quintana Krupinski gives us a brief tour of her deep field camp on the West Antarctic Ice Sheet. Meet glaciologist Slawek Tulaczyk and his team, who work in the fast-emerging field of ice sheet dynamics. They speak to us just after returning from a month at a remote camp on the West Antarctic Ice Sheet. Scientists at Palmer Research Station in Antarctica talk about their research: How is the rich marine ecosystem just offshore responding to melting sea ice and global climate change? Penn State University glaciologist Dr. Richard Alley explains why ice is cool. Today we wrap up our conversations with the ANDRILL scientists (including project leader Dave Harwood) and hear about what lies ahead for the project. Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms).
