Earth History

Investigating how the Earth’s atmosphere, oceans, surface, and interior have changed through time to understand fundamentally important climatic, tectonic, and biogeochemical changes.

We use field and geophysical observations, elemental and isotopic analyses, high-pressure experiments, and numerical models to investigate the evolution of the Earth. Research topics include: recent climate reconstruction, glacial-interglacial cycling, the rise of oxygen in the atmosphere, growth of the continents, and cooling of the Earth’s interior. Our community seeks to integrate observations and models of diverse phenomena across different timescales to understand how and why the Earth’s climate, life, and interior have interacted and varied over our planet’s history.

Kristin Kimble, PhD Candidate in Earth, Environmental, and Planetary Sciences, describes how she uses marine sediment from the tropical Pacific Ocean to reconstruct how Earth’s climate has changed from three million years ago to the present. This talk was part of Research Matters, featuring short talks about research by Brown University Graduate Students on April 21, 2022.
