McMurdo Dry Valleys LTER News

The history of astrobiological research in the McMurdo Dry Valleys and the connections to the LTER are touched in this seminar conducted by Peter Doran

John Priscu's massive effort to explore the world beneath the Ross Ice Shelf has won an international award for his work in Antarctica.

NPR science friday program. Features John Priscu and Diana Wall, covers questions like "What happens when the ice in Antarctica melts?"

As posted:
he frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain.

A new study, led by an Oregon State University geologist, has found that that the salty soils in the region actually suck moisture out of the atmosphere, raising the possibility that such a process could take place on Mars or on other planets.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY, I'm Ira Flatow. Think of Antarctica as the world's largest ice cube. Ninety percent of the world's ice is locked up down there. But Antarctica is also home to one of the fastest-warming spots on the planet, the Antarctic Peninsula. That's the tip that points towards South America.

Diane McKnight, lead PI of McMurdo Dry Valleys, NAE elected member for elucidating the interrelationship between natural organic matter and heavy metals in streams and lakes.
