Welcome to the Environmental Geophysics Lab

How is a rock like the hard disk in your computer? Both record magnetic fields, and store those records – we hope – for long periods of time. We use some of the same tools developed by the recording industry to study the magnetic record captured by rocks. We do this both as a way to understand how Earth’s magnetic field has changed in the past, and as a way to investigate the geological and environmental processes that affect a rock’s magnetic properties.
