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? Celebrate the spring equinox at the Mayan ruins of Chichén Itzá, in the state of Yucatan, Mexico. The alignment of the sun on this day creates the appearance of a shadow, in the form of a serpent, that descends the main staircase of the great pyramid. The Live@Exploratorium crew is there to capture the snake on film and to speak with local archaeologists, archeoastronomers, and solar scientists about this amazing phenomenon. Join the Live@ crew and NASA scientists as we delve into the ancient knowledge of the Chacoans, daily sky watchers who amassed a great knowledge about the movements of the sun. And learn why today's astronomers and solar physicists continue to watch the sun, using modern ground-based observatories and orbiting space telescopes.
