On his teams first day out in the field near Kangerlussuaq, geomorphologist Paul Bierman of the University of Vermont explains what kind of rocks they look for to help determine the last time Greenland was free of ice. 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. The Jakobshavn Isbr 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. 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 Greenland Ice Sheet shots of melting What does a ringed seals breathing hole look like and how do you find one on a vast sheet of sea ice? Dr. Brendan Kelly uses the canine skills of Cooper, a Black Labrador he trained to chase the scent of ringed seals and point to their holes. Passionate about wildlife and climate change, Melanie Duchin has loaned her dog to work with Brendan for the past 5 years. Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems. Join us as we celebrate the beginning of summer in the Arctic and the long, cold winter in Antarctica. We'll connect live to two polar field sites: Summit Camp atop Greenland's vast ice sheet, where the sun will be shining 24 hours a day, and the South Pole Research Station, now in the middle of 6 months of darkness.
