Ice caves on the Mt. Erebus Volcano, frozen lakes in the Dry Valleys and the ice covered McMurdo Sound offer diverse and extremely cold environments in which highly adapted microbial communities use chemical energy from rocks and volcanic gases to build new organic compounds. Join Hubert Staudigel as he presents initial laboratory results and stunning images from the 2012/13 field expedition, including SCUBA diving under the ice and alpine exploration of ice caves.

Eric Allen’s research focuses on the discovery and genetic manipulation of microbial biosynthetic pathways involved in the synthesis of marine natural products such as omega-3 polyunsaturated fatty acids. He is a faculty affiliate of the Scripps Center for Oceans and Human Health, which studies halogenated organic compounds, contaminents found naturally in common seafood as well as manmade chemicals that accumulate in human breast milk.

Ocean acidification, the well-documented increase in ocean acidity resulting from increasing atmospheric carbon dioxide, poses threats to ocean ecosystems that are not yet fully understood. Join ocean chemist Andreas Andersson as he explains the basics of ocean acidification and how his research is allowing him to monitor the function and health of coral reef systems as the ocean changes.

Beach closures resulting from sewage spills and excessive runoff are all too common along the southern California coast. Physical oceanographer Falk Feddersen has spent much of his career working to understand what happens to pollutants once they make into and past the surf zone. Join us to learn how a combination of coastal zone dye release experiments and oceanographic models help us learn more about how sewage is transported and diluted in the ocean. Series: "Jeffrey B.

Dan Kahan, Professor of Law, and Professor of Psychology, Yale University, and Paula Apsell, Senior Executive Producer, NOVA and NOVA scienceNOW, discuss the challenges of understanding and responding to the risk of sea level rise. Moderated by Richard Hutton, Executive Director, Carsey-Wolf Center. Series: "Carsey-Wolf Center" [Science] [Show ID: 25546]

Manta rays are one of the most iconic and mysterious creatures in the sea, and they share several similarities with sharks—their elasmobranch cousins—including threats to their survival. Join Josh Stewart, a Scripps Ph.D. student and associate director of The Manta Trust, who describes the life of manta rays, threats to their populations around the world, and recent conservation successes that provide a ray of hope for this majestic species.

Dr. Kathryn Yusoff, The Lancaster Environment Center, Lancaster University, and Rear Admiral (ret.) Dr. David Titley, Former Deputy Under Secretary for Operations at the National Oceanic and Atmospheric Agency discuss how to plan for an uncertain future. Moderated by Ronald Rice, UCSB Department of Communication, and Co-Director, Carsey-Wolf Center. Series: "Carsey-Wolf Center" [Science] [Show ID: 25547]

Michael Williams, Chief of the Yupiit Nation, Akiak, Alaska, Kalei Nu’uhiwa, Hawai’ian, Researcher & Curriculum developer, and

Roberta Reyes Cordero, Coastal Chumash, Santa Barbara California discuss the human dimensions of risks and concerns of indigenous communities. Moderated by Georgiana Valoyce-Sanchez, Elder, Governing council of the Barbareno Chumash Council. Series: "Carsey-Wolf Center" [Science] [Show ID: 25548]

Carsten Kooyman of the Scripps Institution of Oceanography discusses his work with Emperor Penguins and how scientists learn to live among these magnificently adapted Antarctic creatures. Series: "Jeffrey B. Graham Perspectives on Ocean Science Lecture Series" [Science] [Show ID: 1979]

Protecting sharks from population decline has never been more important. Join us for a discussion about shark conservation with shark researcher Andy Nosal, recent Scripps Oceanography graduate and Birch Aquarium’s new DeLaCour Postdoctoral Fellow for Ecology and Conservation. Learn about threats facing these essential marine predators, such as overfishing, finning, and negative public perception. Series: "Jeffrey B.
