Program in Geophysics

Driven by a fundamental curiosity about processes on Earth and other planets, students in the EAPS Geophysics Program (PG) work to understand complicated physical and chemical interactions—occurring over a broad range of spatial and temporal scales—that result in the rich behaviors of a variety of geosystems. We develop advanced tools of observation to address questions such as: What is the pattern of mantle convection and what are the underlying dynamics? How are subcontinental keels created and preserved? How do magmas and deforming host rocks interact? How can microwave signals help us learn more about the distribution of water vapor in the atmosphere?

Thanks to recent advances in instrumentation and computer power, geophysicists now have access to data sets covering spatial, temporal, pressure, and temperature ranges previously unavailable, opening new and exciting avenues of discovery. Through a combination of theory, field work, and precise laboratory experimentation, we use innovative techniques to gather and examine data crucial for understanding a multitude of geodynamic processes. Leaders in the field, EAPS geophysicists often perform work that is of grave importance to society, investigating such global issues as petroleum reservoirs, atmospheres and climate, and active fault systems.le.

The term geophysics, literally the physics of the Earth and its environment in space is, by nature, a highly interdisciplinary field. Geophysicists seek to understand the interactions among the physical and chemical processes occurring over a broad range of spatial and temporal scales, that result in the rich behaviors of geosystems from the scale of a fault in a rock you can hold in your hand up to tectonic motions on the scale of continents.

As leaders in the field, EAPS geophysicists provide important global insights on issues such as petroleum reservoirs, groundwater flow, climate, and the earthquake cycle.

Looking beyond our planet, our planetary scientists are putting geophysics lessons learnt on Earth to work to understand and remotely sense bodies they encounter in the solar system and beyond.
