Geologists Confirm Oxygen Levels of Ancient Oceans
Zunli Lu and Xiaoli Zhou, an assistant professor and Ph.D. student, respectively, in the Department of Earth Sciences, are part of an international team of researchers whose findings have been published by the journal Geology (Geological Society of America, 2014). View News Article (2014-06-11)

History book of lakes
Does man, through the felling of trees, alpine farming and atmospheric metal pollution produce a more negative effect on lakes than do natural changes, such as climate and vegetation? How long does it take until environmental protection measures actually show effect in lakes? Karin Koinig from the Institute of Zoology and Limnology at the University of Innsbruck tries to find an answer to this... View News Article (2001-02-22)

Scientists make new estimates of the deep carbon cycle
Over billions of years, the total carbon content of the outer part of the Earth -- in its upper mantle, crust, oceans, and atmospheres -- has gradually increased, scientists reported this month in the journal Proceedings of the National Academy of Sciences. View News Article (2015-06-22)

Ancient rocks yield clues about Earth's earliest crust
It looks like just another rock, but what Jesse Reimink holds in his hands is a four-billion-year-old chunk of an ancient protocontinent that holds clues about how the Earth's first continents formed. View News Article (2014-05-30)
