Scientists announced today that a core drilled by the Higgins Lab in Antarctica has yielded 2.7-million-year-old ice, an astonishing find 1.7 million years older than the previous record-holder. Described at the Goldschmidt Conference in Paris by Yuzhen Yan, a graduate student at Geosciences, the ice revealed atmospheric carbon dioxide (CO2) levels that did not exceed 300 parts per million, well below today’s levels.
The Department of Geosciences and Princeton University congratulates Dr. Maria Paula Mateo Fernandez Caso on successfully defending her Ph.D. thesis: "Environmental Changes and Timing of Events During the Cretaceous-Paleogene Transition:  Assessing Consequences of Deccan Volcanism and the Chicxulub Impact" on Wednesday, July 5, 2017.
Ale Hakala ’03 first interest at Princeton was in environmental policy, though she hadn’t given much thought to more technical careers in the environmental field. Her courses, including a freshman seminar in geosciences and a policy-themed class with Greg van der Vink *83, helped to sharpen her focus, and a summer internship with CEE professor Catherine Peters gave her a closer view of research. But the course that would define her career path was geochemistry, taught by professor Satish Myneni.

Moab Khotsong mine claims to be home to the world’s deepest mine shaft: a 3000–meter descent at some 15 meters per second in a shaking cage, with only the arcs of head lamps piercing the darkness. It can be eerily quiet, and the air carries an acrid scent of burnt rock and ammonia from recent dynamiting. “It’s a smell that’d be associated with Hades,” says Tullis Onstott, a geomicrobiologist at Princeton University who has also joined the project.
Princeton and Rutgers researchers have found that climate-related sea-level rise is expected to cause more severe floods in some regions of the country and less severe floods than predicted in other regions of the country.
Princeton’s environmental-science programs are about to get a big boost. Officials announced in April that the University is moving forward with plans for a new building for environmental studies and more resources for ecology and evolutionary biology (EEB), geosciences, and the Princeton Environmental Institute (PEI).
A video from Professors S. George Philander and Mark A. Cane of Columbia University’s Lamont-Doherty Earth Observatory on how they untangled the complex forces that drive El Niño, the world’s most powerful weather cycle. Both professors won the 2017 Vetlesen Prize for achievement in earth sciences this past April.
The Department of Geosciences and Princeton University congratulates Dr. Dario Marconi on successfully defending his Ph.D. thesis: "Use of the Nitrate Isotopes in the Ocean Interior to Explore the Isotopic Composition of Sinking Nitrogen and its Implications for Marine Biogeochemical Cycles" on Thursday, May 18, 2017.
New evidence suggests that a nutrient that is both essential to life and an environmental scourge when present in large quantities is increasing in the open ocean, according to a new study published May 19 in the journal "Science." The increase of this nutrient, known as “fixed” nitrogen, was studied in coral. The findings give researchers new insight into ocean ecosystems.
