In this audio dispatch, correspondent Saffia Hossainzadeh describes her journey to her team's deep field site via a stop at Siple Dome station. In part one, hear about the difficulties involved in escorting 700 pounds of explosives through Antarctica. In this audio dispatch, correspondent Saffia Hossainzadeh describes her journey to her team's deep field site via a stop at Siple Dome station. In part two, hear about our combat-style landing at Siple Dome’s remote air strip. On his team’s 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. Meet glaciologist Slawek Tulaczyk and his team, who work in the fast-emerging field of ice sheet dynamics. They speak to us just after returning from a month at a remote camp on the West Antarctic Ice Sheet. Penn State University glaciologist Dr. Richard Alley explains why ice is cool. 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. Join Senior Scientist Paul Doherty as he explains the difference between floating ice and land ice, and why they effect sea levels differently. Stephanie Chasteen speaks with Jerry Osborne of the University of Calgary about his work studying glaciers to understand how the climate is changing in recent years. Chris McKay, Planetary Scientist at the NASA Ames Research Center, has traveled the world seeking Mars-like environments. In the Dry Valleys of Antarctica—his favorite Mars analog on Earth—Dr. McKay discovered a kind of algae living inside rocks porous to light and water. He’ll show us some of these rocks and talk about the physical conditions required for life. In preparation for the 2004 landing of the Mars Exploration Rovers, NASA engineers and scientists tested their remote operation procedures using a rover called FIDO (field integrated design & operations rover). Our remote team traveled to the desert test site to see what they learned in the desert and what they hoped to learn on Mars.
