Greenland, shots taken while flying in a helicopter from the Ilulissat Airport out over the Greenland ice sheet to the remote field camp of researcher Sarah Das. From a small rubber boat on a Greenlandic lake, climate researcher Billy D'Andrea introduces some of the equipment scientists use in limnological sampling. (Limnology is the study of freshwater systems, like lakes.) 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. In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: dental hygiene products! While hiking back from a research site near Kangerlussuaq, Greenland, Ice Stories correspondent Billy D'Andrea happened upon a Peregrine Falcon scrape. Two falcons, not too thrilled that he was passing by their cliff-side nest, began circling and screaming to chase him off. In this video, listen for the sound of Wheatears (songbirds) chirping and yipping in the foreground. Shots of the calving front of the Jakobsavn Glacier, Greenland's fastest moving glacier. Includes two shots of Mark Fahnestock's helicopter flying over. Working in the snow all day takes a certain type of skill set: digging skills, drilling skills, and snowmobile driving skills. It also helps to love what you do. Various shots of the margin of the Russell Glacier Shots on the Greenland Ice Sheet, including water running off Arctic Fox kits in the grass.
