Antarctic Rocks Provide Clues to Bigger Earth Questions
John Goodge of the University of Minnesota Duluth is studying rocks from the 2 percent of Antarctica that is not under ice in search of clues to the rest of the continent: how it formed and shaped over time, along with what’s under the ice sheet. His team also hopes to learn more about the history of ancient continents, the health of the planet and the impacts of global climate change.
