On Speeding Glaciers and Huge Icebergs, Part 2

KANGERLUSSUAQ, GREENLAND– Last week, we showed you a video interview with glaciologist Mark Fahnestock who described how he and his team are measuring the motion of the Jakobshavn Isbræ, one of the fastest-moving glaciers in the world.

Here, Dr. Fahnestock describes the roar of a 1000-foot iceberg dropping off the Jakobshavn into the Ilulissat Icefjord. Watch 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, Dr. Fahnestock discusses glacier dynamics and what he hopes to learn through his studies.
