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.

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.

Ice Stories:  The Tundra and Climate Change (Webcast)
Running Time:
00:16:26
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?

Ice Stories:   The Road to ANDRILL (Clip)
Running Time:
00:04:45
In this video, ride in a special Mattracks truck across the ice sheet with geologist Christina Riesselman as she travels with ANDRILL Staff Scientist Richard Levy from McMurdo Station to the ANDRILL drill site. They investigate the truck’s special wheels, observe beautiful panoramas of the Transantarctic Mountains, and hear the drill running at the drill site.
