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.

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.

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 (60x real-time 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.
