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 (100x real 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. Time interval on this timelapse is 10 seconds per frame.

In this video, ride in a special Mattracks truck across the ice sheet with geologist Christina Riesselman as she travels with ANDRILL Staff Scientist Richard Levy from McMurdo Station to the ANDRILL drill site. They investigate the truck’s special wheels, observe beautiful panoramas of the Transantarctic Mountains, and hear the drill running at the drill site.
