Wiens heads seismology effort in international Antarctic study

Douglas A. Wiens, Ph.D., professor and chair of earth and planetary sciences in Arts & Sciences, will head the seismology research team of an ambitious international effort to map and analyze an unknown part of Antarctica. The project is called AGAP (Antarctica’s Gamburtsev Province) after the Gamburtsev Subglacial Mountains, which are the main feature of the region. Wiens, Patrick Shore, computer specialist in earth and planetary sciences, and graduate students David Heizel and Amanda Lough will install 26 seismographs on the frozen surface of central Antarctica, a part of the world that is a geological mystery.

Return to Europa: A closer look is possible

NASA/JPLThick or thin ice shell on Jupiter’s moon Europa? Scientists are all but certain that Europa has an ocean underneath its surface ice, but do not know how thick this ice might be.Jupiter’s moon Europa is just as far away as ever, but new research is bringing scientists closer to being able to explore its tantalizing ice-covered ocean and determine its potential for harboring life. William B. McKinnon, professor of earth and planetary sciences at Washington University in St. Louis, is discussing some of these recent findings and new opportunities for exploring Europa in a news briefing on Thursday, Dec. 13, 2007, at the meeting of the American Geophysical Union in San Francisco.
