Glen Penfield used magnetic and gravitational field measurements as part of the evidence to identify the Chicxulub crater. These geophysical methods helped reveal the structure and characteristics of the crater beneath the surface. His work contributed significantly to the understanding of the impact event associated with the mass extinction at the end of the Cretaceous period.
