GEOS - Captain Jack & the Halogen Hunters
(Click the RETURN Button to Return to Media Palooza)

In this 2-part research-oriented podcast, "Captain Jack" Dibb - who's been doing snow and atmosphere research at Summit Station since 1989 - leads a dynamic and diverse crew of colleagues, undergraduates and grad students in a state-of-the-art experiment designed both to address basic scientific questions ("Do ice core records reflect what actually happens to gases trapped in snow?") and social issues: "Do model projections of Earth's atmosphere account for all the elements and molecules actually present?" You'll see the harsh conditions in which they work, and how they sample snow and atmosphere. Professors and students alike walk miles to work each day - ensuring their open air lab remains a "clean air sector" where generators and snowmobiles are banned.
