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? Join us as UC Berkeley's Dr. Robert Levenson interviews acclaimed psychologist Dr. Paul Ekman about his 40 years of research into the universality of human facial expressions. The talk includes photographs and never-before-seen footage from Dr. Ekman's fieldwork among the Fore, an isolated New Guinea tribe he first visited in the early 1960s. Dr. Tejal Desai of UCSF talks about the intersection of nanotechnology and medicine, an area of research that has dramatic implications for the future. It could lead to artificially engineered tissues, or more effective drug delivery. It could also result in new kinds of health monitoring devices, as Dr. Thomas Murray, from the Hastings Center, explains. Join Exploratorium biologist Karen Kalumuck as she leads a Darwin 101 Webcast using hands-on explorations, audience participation, and special surprises—just in time to celebrate his birthday!
