Princeton University’s Department of Geosciences is at the forefront of scientific discovery in Earth physics and geology, Earth chemistry and biology, and the study of Earth's ocean, atmosphere, and climate. The Geosciences Department, together with its affiliated inter-departmental programs and institutes, serves as the central focus for the Earth, atmospheric, oceanographic, and environmental sciences at Princeton. As such we encompass a rich diversity of scientific expertise and initiative that ranges, for example, from the measurement and modeling of global climatic change, to high-pressure mineral physics, to seismic tomographic imaging of the Earth's interior or the analysis of terrestrial and planetary tectonics.
