Geoscientists Take Part in Frontera Supercomputer

UC Davis scientists are taking part in a project to build the new “Frontera” supercomputer at the University of Texas at Austin. Funded by a $60 million grant from the National Science Foundation announced last week, Frontera will be the fastest computer at any U.S. university and among the most powerful in the world.

There and Back Again: Mantle Xenon Has a Story to Tell

By Talia Ogliore

The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to incorporating and retaining volatile compounds such as water, nitrogen and carbon from the atmosphere in the mantle before spewing them out again through volcanic eruptions.

This transport could not have begun much before 2.5 billion years ago, according to researchers at UC Davis and Washington University in St. Louis, published Aug. 9 in the journal Nature.

Augmented Reality Sandbox Hits Worldwide Milestone

By Becky Oskin

With more than 500 installations on six continents, the UC Davis Augmented Reality, or AR, Sandbox, has become a worldwide phenomenon.

The AR Sandbox brings earth science to life by merging hands-on play with digital effects. The setup combines a real sandbox with a motion-sensing camera (such as a Microsoft 3D Kinect) and a digital projector. As people shape the sand with their hands or with tools, the camera detects the changes and a computer projects colors depicting elevation, vividly illustrating the principles of topographic maps. Users can also create rainstorms, lakes and rivers and immediately see how reshaping the sand surface changes the water flow.
