Blue Marble: Explore the Possibilities

Welcome! Climate, biogeochemical cycles, and planetary tectonics are the three basic processes that shape the environment. Geoscientists face a unique challenge in seeking to understand the complexity of the Earth's physical and biogeochemical systems. The surface environment of the Earth is controlled by interactions between the deep Earth, the atmosphere, the hydrosphere, and the biosphere. These interactions occur on timescales ranging from picoseconds for chemical reactions on mineral surfaces to the billions of years over which plate tectonic processes and biological evolution have radically altered the composition of the atmosphere. Princeton’s Department of Geosciences is at the forefront of scientific discovery in the solid earth, the environmental geosciences and oceanography/climate science. Our faculty and students address critical societal issues, such as climate change and geologic hazards, through research and education at all levels. Our mission is to understand Earth’s history and its future, the energy and resources required to support an increasing global population, and the challenge of sustainability in a changing climate. Interested in coming to Geosciences for graduate school? Please get in touch with individual faculty members to find out more and ask about visiting us!

Faculty Spotlight

Prof. Fueglistaler

Professor Stephan Fueglistaler
Associate Professor of Geosciences. Dusenbury University Preceptor of Geological and Geophysical Sciences. Director, Program in Atmospheric and Oceanic Sciences.

Our primary research interest is the interaction of dynamical, physical and chemical processes across the wide range of scales in the atmosphere.  We focus on radiatively active atmospheric trace constituents whose abundance is sensitive to atmospheric motion (specifically: ozone, water vapor and clouds), and how these interactions shape Earth's climate as we know it. Working with observations, theory and numerical models ranging from highly idealised to highly detailed, our vision is to improve the understanding of the hierarchy of importance of processes governing Earth's climate, and to explain the climatic base state with the minimum amount of a priory information.
