Ice Stories: Why We Install GPS Systems (podcast)

Running Time:
00:03:19

The POLENET project installed their newest high-precision GPS system on Deverall Island, Antarctica. These GPS systems tell scientists how much the ground underneath the ice sheet is moving upward. This has important implications on the movement of the West Antarctic Ice Sheet and its interplay with the rock below. Learn more about it in this audio report from correspondent Kelly Carroll.

Ice Stories: Interview with Glaciologist Mark Fahnestock, Part 1 (clip)

Running Time:
00:02:53

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.
