Ice Stories correspondent Chico Perales is a great adventurer, photographer, and field coordinator for scientists. He's spent many seasons in Antarctica, but has finally made North to Barrow. Join us as we listen to Chico's incredible tales from both poles, and learn about what it takes to get scientists out on the ice.

How does the interaction of solar radiation on sea ice effect climate change? Please join us as we chat live with Dr. Don Perovich, an expert in the fields of albedo effect, and sea-ice mass balance on climate.

Brendan Kelly learned from Inuit hunters how to train Labrador retrievers to find ringed seals. This allows Brendan and his colleagues to set up live-capture nets to keep the seals from diving after they come up for air. The seals are tagged with satellite transponders so they can be tracked to learn about their breeding grounds and migration habits.

One of the first projects to move into the new BASC(Barrow Arctic Science Consortium)facility, the archeologist team of Anne Jensen and Laura Thomas, are preparing for their season of digging up the past. We will catch up with them in their lab: take a look at their tools and specimens, and learn about their plans as they prepare for their upcoming field work.

Learn more about the new mission to Mars! The Mars Phoenix Lander touched down on the Red Planet on Sunday, May 25, 2008, and began collecting data. Phoenix is designed to study the history of water and search for complex organic molecules in the Martian arctic's ice-rich soil. Join Exploratorium Senior Scientist Paul Doherty as he walks us through the mission and shows us the first pictures that the Phoenix Lander sends back!

In our second Webcast with biologist Steve Hastings, we'll learn about his collaborative research experiment in Barrow. As the climate changes in the Arctic, the amount of water on the tundra is affected (more rainfall, shorter freeze periods, changing sea levels,etc). How will these changes effect the tundra's release of greenhouse gases? Will less permafrost mean more or less CO2 in the atmosphere? Will warmer temperatures cause more evaporation? Will that be good or bad for the environment?

The Census of Marine Life is a growing global network of researchers in more than 70 nations engaged in a ten year (2000-2010) mission to assess and explain the diversity, distribution, and abundance of marine life in the oceans. Rolf Gradinger is an expert in Sea Ice Communities, studying the tiny animals that actually live inside the ice and those that live on the bottom of the ice sheets. We'll chat with Rolf about his current work, drilling ice cores just off Barrow, and looking for some of the world's most unique fauna.

Meet Barrow scientist and Ice Stories blogger Steve Hastings, who is investigating how the tundra responds to climate change. What exactly is the tundra? How can vegetation, no more than 3 inches tall, play such an important role in the world's climate? Why does the tundra release so much CO2?

The Exploratorium's remote crew has landed in Barrow, AK, to showcase the vast array of science being conducted at this northernmost tip of the continent. Join us for this introduction to Barrow: where is it? why are so many scientists here? why are May and June such important times?

At the National Ice Core Lab in Denver, Colorado, scientists study ice cores in a Class 100 clean room lab kept at minus 7 degrees F.
