Christina, a geologist from Stanford University, investigates climate history by scouring sediment samples for diatoms, microscopic marine creatures that lived long ago in Antarctica's McMurdo Sound. Pulling food to prepare for four weeks at the West Antarctic Ice Sheet camp. A video portrait of Barrow, Alaska, the northernmost settlement in the United States. Craig George and Glenn Sheehan explain how scientists have learned from Iñupiaq hunters to make more accurate counts of bowhead whales. Interview with Ice Stories correspondent and archeologist, Ann Jensen. Footage of a small gray whale in the Chukchi Sea near the Barrow shoreline. Interview with Paolo Paulo Olivas about his research at the Barrow Environmental Observatory (BEO). Paulo Olivas points out the different equipment he uses to measure the amount of greenhouse gases being released from the tundra. The Jakobshavn Isbrae 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 by Jason Amundson of the University of Alaska Fairbanks 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. Dr. Tejal Desai of UCSF talks about the intersection of nanotechnology and medicine, an area of research that has dramatic implications for the future. It could lead to artificially engineered tissues, or more effective drug delivery. It could also result in new kinds of health monitoring devices, as Dr. Thomas Murray, from the Hastings Center, explains.
