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! 

Special thanks to GEO students, staff, and faculty who have supplied photos for our slideshow.

Faculty Spotlight


Professor Laure Resplandy

Assistant Professor of Geosciences
Area(s): Oceanography and Climate

Prof. Resplandy is a biogeochemical oceanographer in geosciences and the Princeton Environmental Institute. Her research goals are to understand how climate and ocean physics influence marine biogeochemistry and ecosystems, and how these changes can in turn impact the climate itself. Resplandy’s approach is to design and develop numerical models (from ocean regions to global climate system) and statistical tools to interpret in-situ and satellite observations.

Resplandy joined the faculty in spring 2017 from the Scripps Institution of Oceanography at the University of California-San Diego. She also worked at the Laboratoire des Sciences du Climat et de l’Environnement, Paris and at the National Oceanography Center, Southampton prior to coming to Guyot Hall.  LEARN MORE
