Ice Stories: First Day in the Field (webcast)

Running Time:
00:32:01

Weather permitting, correspondents Anne Jensen and Laura Thomas will have just returned from their first day at their field location at Nuvuk (a.k.a. Point Barrow). We'll take a look at conditions after the long winter, and watch as these scientists, and their students, prepare for a summer of digging.

Ice Stories: Snow Chemistry (webcast)

Running Time:
00:22:08

As the Arctic continues to warm, chemicals locked in the snow can be released-either into the seas or evaporated into the air. Dr. Glenn Rowland studies the chemicals locked in the ice to help us understand what is there now and how it will react when released into the environment.

Ice Stories: Tales of Adventure (webcast)

Running Time:
00:24:06

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.

Ice Stories: Sea Ice and Albedo Effects on Climate with Dr. Don Perovich (webcast)

Running Time:
00:16:56

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.

Ice Stories: Sniffing out Seals (webcast)

Running Time:
00:32:06

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.

Ice Stories: Preparing to Dig (webcast)

Running Time:
00:28:47

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.

Return to Mars: Mars Phoenix Lander Mission (webcast)

Running Time:
00:28:34

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!

Ice Stories: The Tundra and Climate Change, Part 2 (webcast)

Running Time:
00:19:01

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?

Ice Stories: Searching for Life in the Ice (webcast)

Running Time:
00:22:45

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.
