Dates: Dec. 13, Jan. 10, Feb. 14 Time: 6:30-8 p.m. Public: $8 Students/Educators: $5 RSVP: 858-534-5771 Explore Earth's mysteries through the Jeffrey B. Graham Perspectives on Ocean Science Lecture Series, presented monthly at Birch Aquarium at Scripps. From the cosmos to the ocean abyss, join Scripps researchers on their paths to discovery in this acclaimed series. San Andreas Fault.

Join Scripps Oceanography geoscientist Neal Driscoll as he presents new findings on a possible relationship between these earthquakes and the flooding of Lake Cahuilla, which forms episodically as the Colorado River switches course and flows north into the Salton Trough. Learn how new data on the timing and magnitude of past earthquakes are being used to assess the potential for large earthquakes in the region. Monday, Jan. 10 Postponing the End of Oil: The Search for Offshore Energy Resources Steve Constable, Scripps geophysicist Peak oil may have come and gone, yet we are using oil faster than we are discovering it and have only just begun to think about alternatives. Join Scripps Oceanography geophysicist Steve Constable and learn how he is using sophisticated marine electromagnetic techniques to find dwindling offshore reserves during our transition from the hydrocarbon age to "beyond petroleum." Monday, Feb. 14 The Birth of Icebergs: Glacier Calving and Ice-quakes Fabian Walter, Scripps glaciologist New iceberg formed in Antarctica. Photo: NOAA If both polar ice sheets melted completely, global sea level would rise by about 64 meters (210 feet). Although this drastic scenario will not occur in the near future, we are witnessing a substantial rise in sea level due to glacial retreat. Join Scripps Oceanography post-doctoral scholar Fabian Walter as he describes how icebergs "calve" off of glaciers. Learn how techniques traditionally applied to studying earthquakes are being used to unravel the complexities of this process and how they are helping researchers better predict how glaciers interact with oceans in a changing climate. Perspectives lectures are intended for a lay audience. Birch Aquarium admission and parking are included. Light refreshments are available. Past lectures air on UCSD-TV and are broadcast to more than 16 million viewers via satellite and cable television. Archived lectures also can be found online.

About Birch Aquarium at Scripps Birch Aquarium at Scripps is the public exploration center for the world-renowned Scripps Institution of Oceanography at UC San Diego. Perched on a bluff overlooking the Pacific Ocean, the aquarium features more than 60 habitats of fish and invertebrates from the cold waters of the Pacific Northwest to the tropical waters of Mexico and the Caribbean. An interactive museum showcases research discoveries by Scripps scientists on climate, earth and ocean science. Accredited by the Association of Zoos and Aquariums, Birch Aquarium has an annual attendance of more than 410,000, including 45,000 school children.
Note to broadcast and cable producers: University of California, San Diego provides an on-campus satellite uplink facility for live or pre-recorded television interviews. Please phone or email the media contact listed above to arrange an interview.
About Scripps Institution of Oceanography Scripps Institution of Oceanography at the University of California, San Diego, is one of the oldest, largest, and most important centers for global science research and education in the world. Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical, and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today on every continent and in every ocean. The institution has a staff of about 1,400 and annual expenditures of approximately $170 million from federal, state, and private sources. Scripps operates robotic networks and one of the largest U.S. academic fleets with four oceanographic research ships and one research platform for worldwide exploration. Birch Aquarium at Scripps serves as the interpretive center of the institution and showcases Scripps research and a diverse array of marine life through exhibits and programming for more than 425,000 visitors each year.
