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.

Faculty Spotlight

Professor David Medvigy
Assistant Professor, Department of Geosciences and
Program in Atmospheric and Oceanic Sciences (AOS)


My group's research focuses on the 3-way intersection between terrestrial ecosystems, the atmosphere and anthropogenic drivers of global change.  We seek to understand the natural laws that, at this intersection, govern the flows of water, energy and carbon between terrestrial ecosystems and the atmosphere, and that ultimately determine the dynamics of terrestrial ecosystems and the atmosphere.  Our approach is to develop state-of-the-science predictive models that enable us to answer fundamental questions at the intersection of ecosystems and climate in the Anthropocene.
