Ice Stories:  Sandpiper Egg Swap (Clip)
Running Time:
00:03:18
Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, and his team fashion fake Sandpiper eggs, swap them for the real ones in the nest and incubate them in their lab at BASC’s (Barrow Arctic Science Consortium) new research facility. Once the hatchlings emerge, they take samples from them to determine factors such as paternity. The chicks are then returned to the nest, without the mother batting a feather.

Ice Stories:  Jakobshavn Isbræ Calving Timelapse, May 10, 2008 (Clip)
Running Time:
00:00:54
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.
