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. Nadine, a glaciology graduate student from UC Santa Cruz, spent four weeks on the West Antarctic Ice Sheet investigating ice sheets and global climate change. Dr. Tulaczyk, a glaciologist from UC Santa Cruz, studies the lakes, floods, and ice quakes that occur under the giant glaciers of Antarctica. He is among only 200 scientists world-wide who study ice sheet dynamics and its role in climate change. Pulling food to prepare for four weeks at the West Antarctic Ice Sheet camp. Join us as we talk with Dr. William Fry, emeritus professor at Stanford University and the father of gelotology, the study of humor and laughter, and their effects on the human body. The Exploratorium's Ron Hipschman shows how a double disk with a string attached is a great way to study the physics of motion. Then Captain Yo and Doc Popular astound with amazing yo-yo tricks. A video portrait of Barrow, Alaska, the northernmost settlement in the United States.
