What is dark energy? Cosmologist Rocky Kolb explains how the South Pole Telescope will help us understand the properties and nature of this mysterious force. Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms). How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it? Join us for an overview of the ANDRILL (ANtarctic geological DRILLing) Project, a multinational collaboration among 200-plus scientists, students, and educators from five nations, to recover sediment cores (layered sections of earth) from under the Antarctic ice and seas. 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.
