The Department of Geosciences and Princeton University congratulates Dr. Jessica Lueders-Dumont on successfully defending her Ph.D. thesis: "Nitrogen Isotopes of Otolith-Bound Organic Matter: A New Tool for Trophic Reconstruction Using Modern and Fossil Otoliths" on Friday, May 3, 2019.
When the landmass that is now the Indian subcontinent slammed into Asia about 50 million years ago, the collision changed the configuration of the continents, the landscape, global climate and more. Now a team of Princeton University scientists has identified one more effect: the oxygen in the world’s oceans increased, altering the conditions for life.
When nitrogen-based fertilizers flow into water bodies, the result can be deadly for marine life near shore, but what is the effect of nitrogen pollution far out in the open ocean? A 130-year-old brain coral has provided the answer, at least for the North Atlantic Ocean off the East Coast of the United States.
