Humans are adding new reactive forms of nitrogen (N) into the environment, which has the potential to cause a range of problems. Andrew Babbin and Prof. Bess Ward set out to address this problem in the lab by constructing a series of mesocosms out of sediments from the Chesapeake Bay, United States, with large amounts of organic matter added to some of the columns.
Jessica Irving joined the Department of Geosciences on Feb. 1, 2013, as an assistant professor for a term of three and a half years. Irving will be teaching GEO 203 "Fundamentals of Solid Earth Science" in the fall alongside Prof. John Higgins.
A study of sed­i­ment cores col­lected from the deep ocean sup­ports a new expla­na­tion for how glac­ier melt­ing at the end of the ice ages led to the release of car­bon diox­ide from the ocean.

Nine students have received the 2013 Spirit of Princeton Award, which recognizes positive contributions to the University community. Undergrad Nathan Mathabane ’13 and others were selected from a pool of applicants who were nominated by other members of the University community.
Princeton professors have been studying extreme weather, ­natural disasters, and their impact on people and property for years, but Hurricane Sandy pushed their research to the forefront. No longer was their work theoretical: It now is ­discussed in front-page newspaper stories and in government offices, particularly in and around New York City.
On Friday, March 22, 2013, Post-doc Mélanie Barboni and Grad student Brenhin Keller, were given the opportunity to interact with the community by providing a departmental tour hosted by the Princeton Plasma Physics Lab (PPPL). The tour was part of the “The Young Women’s Conference in Science, Mathematics, Technology, and Engineering.”
This conclusion was reached at a multidisciplinary international conference on "Volcanism, Impacts and Mass Extinctions: Causes and Effects” held on March 27-29, 2013, at the Natural History Museum of London. The meeting brought together 150 experts from diverse fields across geosciences and astronomy to assess, discuss and evaluate research in this field over the past several years.
April’s Mineral of the Month brings us one of the minerals commonly referred to as “fool’s gold,” Pyrite.
