Chemical and biological interactions shape Earth's surface environments, including the atmosphere, soils, sediments, oceans, and groundwater. Princeton researchers investigate marine nutrient dynamics and biological activity, global cycles of nitrogen and carbon, the significance of metals in marine and terrestrial ecosystems, ocean acidification, and extremophile contributions to geochemical processes on Earth and possibly Mars. The Geosciences Department, along with its interdisciplinary programs and research centers, forms Princeton's core hub for Earth, atmospheric, oceanic, and environmental science research. This academic unit brings together diverse scientific specialties aimed at deciphering Earth's interior structure, climate systems, biosphere, atmospheric and oceanic processes, surface features, and their complex interactions across geological timescales.
