Join A, K. C. Cole, author of Something Incredibly Wonderful Happens: Frank Oppenheimer and the World He Made Up, in conversation with Exploratorium Director Dr. Dennis Bartels, eminent San Francisco Chronicle science writer David Perlman, Cinema Arts Director Liz Keim, and Exploratorium physicist Thomas Humphrey. A question-and-answer session followed the panel discussion.
Produced by Thorne Films, this very early 1972 film details some of the history and thought that went into the creation of the Exploratorium as told by its founding director, Frank Oppenheimer. Geologist Chistina Riesselman explains how studying 3-million-year-old sediment from Antarctica is providing a glimpse of what our planet's climate might look like if atmospheric carbon dioxide continues to rise as projected. Dr. Marvin Speece, professor of geophysical engineering at Montana Tech and co-Principal Investigator of the Offshore New Harbor Project, discusses how their expedition collects scientific data. From a small rubber boat on a Greenlandic lake, climate researcher Billy D'Andrea introduces some of the equipment scientists use in limnological sampling. (Limnology is the study of freshwater systems, like lakes.) Working in the snow all day takes a certain type of skill set: digging skills, drilling skills, and snowmobile driving skills. It also helps to love what you do. To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae. At the National Ice Core Lab in Denver, Colorado, scientists study ice cores in a Class 100 clean room lab kept at minus 7 degrees F. The Exploratorium celebrates the 20th anniversary of Pi Day with a pie-throwing contest, Pi Day exhibits in Second Life, and more activities honoring everyone's favorite mathematical constant. In this video, ride in a special Mattracks truck across the ice sheet with geologist Christina Riesselman as she travels with ANDRILL Staff Scientist Richard Levy from McMurdo Station to the ANDRILL drill site. They investigate the truck’s special wheels, observe beautiful panoramas of the Transantarctic Mountains, and hear the drill running at the drill site.
