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. 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. Daniel Lum talks about the changes in ocean ice near Barrow. 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. B-Roll for playback during webcast, "Tundra and Climate Change with Steve Hastings," on 5/24/08. Footage includes shots of data gathering, facilities and landscape at the Barrow Environmental Observatory. Join host Mary Miller and Dr. Mickey Glantz in a discussion on issues around climate change and how it may affect communities. Join Exploratorium staff scientist Charlie Carlson as he continues to examine issues around the Gulf Stream and climate change.
