Dusenbury Professor of Geological and Geophysical Sciences Daniel Sigman has been recognized for excellence in Graduate Student Mentoring. (Updated version) Featuring comments by Lisa Herschbach, director of the McGraw Center for Teaching and Learning and associate dean of the college regarding Prof. Sigman.
Prof. Em. Lincoln Hollister writes in "As a scientist who cares about evidence-based decision making, I'm astounded that Clean Ocean Action (COA) has chosen to misrepresent facts in order to shovel sand against sea level rise." Get the Facts on NJ Sea Levels:
Three Princeton University-related computer programs have been chosen to run on a new supercomputer that will deliver enhanced scientific findings when it begins crunching numbers in 2018. The three projects were among 13 selected to run in the Center for Accelerated Application Readiness program at the Department of Energy's Oak Ridge Leadership Computing Facility.
Please join The Department of Geosciences in congratulating the

More than 2,000 Princeton University students will graduate at Commencement on Tuesday, June 2.  GEO Undergrad Joan Cannon '15 appears in this video and thanks her peers who helped her succeed to graduation (1:41).
The 2015 "Smilodon" alumni newsletter is now published and available in the department and online. Geosciences Alumni can look for copies to be delivered this summer.
A team of researchers with members from Princeton University, the University of Maine and Oregon State University has found that greenhouse gasses a million years ago, were only slightly higher than they were between 450,000 and 800,000 years ago. In their paper published in "Proceedings of the National Academy of Sciences," the team describes their study of the newly retrieved ice cores and how it is helping to better understand the changes to the Earth's ice ages.
A whiff of air frozen in ice for 1 million years provides a new snapshot of Earth's ancestral climate. "Gas bubbles are the gold standard for reconstructing climate," said lead study author John Higgins, a geochemist at Princeton University. (DOI:10.1073/pnas.1420232112)
Deforestation is believed to cause drier and warmer conditions because of a decrease in tree cover. However, a counterintuitive effect of increase in cloudiness and rain due to deforestation has been found by Khanna and Medvigy in Rondônia, a state in west central Brazil, which was once covered by over 50 million acres of Amazonian rainforests, half of which has been replaced by pasture.
