According to TED.com: “Hundreds of meters below the surface of the ocean, Laura Robinson probes the steep slopes of massive undersea mountains. She’s on the hunt for thousand-year-old corals that she can test in a nuclear reactor to discover how the ocean changes over time. By studying the history of the earth, Robinson hopes to find clues of what might happen in the future.”
“Dr. Laura Robinson’s research the processes that govern climate on time scales ranging from the modern day back through hundreds of thousands of years. To do this research, Robinson uses geochemical techniques, with an emphasis on radioactive elements including uranium series isotopes and radiocarbon. These elements are particularly valuable as they have a wide range of decay rates and geochemical properties and can be analyzed in geologic materials such as corals, marine sediments and seawater.”
For those of you not familiar with TED Talks here is a brief summery from www.ted.com: “TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader. Along with two annual conferences — the TED Conference in Long Beach and Palm Springs each spring, and the TEDGlobal conference in Oxford UK each summer — TED includes the award-winning TEDTalks video site, the Open Translation Project and Open TV Project, the inspiring TED Fellows and TEDx programs, and the annual TED Prize”
