In this interview from Greenland, glaciologist Mark Fahnestock describes the roar of a 1000-foot iceberg dropping off the Jakobshavn Isbræ into the Ilulissat Icefjord. Includes time-lapse photography of this massive calving event. What controls the speed of Greenland’s big outlet glaciers like the Jakobshavn? How do they interact with the climate system? And most importantly, what does the future hold for the glaciers of Greenland? In this video, glaciologist Mark Fahnestock discusses glacier dynamics and what he hopes to learn through his studies. An interview with Isabel Hawkins, Co-director/Research Astronomer, UC Berkeley Space Sciences Laboratory; Co-director, NASA Sun-Earth Connection Education Forum.
When astronomer Isabel Hawkins began exploring the astronomical work of Native Americans, their knowledge broadened
her view of the night sky. She's since discovered several scientists incorporating the work of native people, both modern and ancient, into their current-day research. Isabel describes how she sees science as a cultural construct, the value of learning from personal experience, and that evidence comes in many forms.
The Ice Stories crew caught up with glaciologist Mark Fahnestock on his way back home after a few weeks camping near Greenland's Jakobshavn Isbræ, the most productive and among the fastest-moving glaciers in the world. In this interview, Mark describes some of the physics of this speedy glacier and why so many scientists are interested in studying the dynamics of Jakobshavn. On August 1, 2008, a total solar eclipse occurred as the new moon moved directly between the sun and the earth. The moon's umbral shadow fell on parts of Canada, Greenland, the Arctic Ocean, Russia, Mongolia, and China. The Exploratorium's eclipse expedition team (our fifth!) Webcast the eclipse live from the remote Xinjiang Uygur Autonomous Region in northwestern China near the Mongolian border. Watch totality highlights. Watch the telescope-only stream of the total solar eclipse that occurred on August 1, 2008. In the summer of 2008, the only helicopter in Kangerlussuaq, Greenland, was effectively grounded by a diamond company, leaving scientists and logistics coordinators to frantically rearrange their field plans. Musk oxen graze on a rock ledge outside the town of Kangerlussuaq, Greenland. (No audio attached). In this video interview from Greenland, geologist Tom Neumann from the University of Vermont explains how he and his colleagues are attempting to read the history of the Greenland Ice Sheet by collecting and analyzing rocks spit out from the base of the glacier.
