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. 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? Hear more from scientists working on the Ice Cube telescope at the South Pole. Watch as three giant helium balloons are launched above Antarctica to study climate history; listen as scientists talk about balloon research. Today we wrap up our conversations with the ANDRILL scientists (including project leader Dave Harwood) and hear about what lies ahead for the project. Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms). How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it?
