On March 1st, we connected live with scientists aboard the scientific drilling vessel the JOIDES Resolution off the coast of Antarctica. Meet geologists Rob Dunbar, Carlota Escutia, and Christina Riesselman and learn about their historic expedition to Antarctica that is helping reveal the history of Earth's climate and teaching us about our climate future. Astrophysicist Paul Coleman and expert ocean navigator Kalepa Baybayan visited the Exploratorium as advisors to our Polynesian Navigation project—a large-scale Web resource (launching April 2010) that will feature the astounding navigation practices of the Pacific Islanders, who were expertly navigating the Pacific thousands of years before the arrival of Europeans.
Paul Coleman works at the University of Hawaii Institute for Astronomy, where he concentrates on the large-scale structure of the universe. Kalepa Baybayan is an expert navigator who mentors Hawaiian youth in native navigation practices. Both men are native Hawaiians. We spoke with them about traditional navigation practices, the balance between science and spirituality from a native perspective, and the benefits of being grounded in one’s culture.
In May 2009, the ROV Jason captured these images of violent explosions of the West Mata volcano near Fiji. At almost 4,000 feet underwater, this is the deepest erupting volcano ever witnessed and captured on video. It's also the first time anyone has ever observed the formation of deep-ocean seafloor as it's happening. We talk to photographer John Weller, who spent the austral summer 2008 scuba diving under the ice in Antarctica. Hear from marine biologist Dr. Stacy Kim, who uses a small camera-equipped remotely operated vehicle (ROV) to investigate the bottom-dwelling creatures under the sea ice. Daniel Lum talks about the changes in ocean ice near Barrow. Join Exploratorium staff scientist Charlie Carlson as he continues to examine issues around the Gulf Stream and climate change. Meet Breea Govenar, a biologist at Penn State University, as she speaks to us from aboard a research vessel from Wood's Hole Oceanographic Institute. She'll discuss life near deep-sea thermal vents in the Pacific Ocean. The Webcast also includes Dr. Alissa Arp, a biologist from San Francisco State University studying the tube worms that live around these very hot marine spots. Jonathan Trent, Astrobiologist, NASA Ames Research Center studies "thermophiles," heat-loving microbes inhabiting places once thought too hostile for life, but analogous to environments that might be found on other planets. He discovered that some of these microbes make a protein that appears to stabilize their cell membranes (and may have applications for nanotechnology).
