Geoscience Tetrahedron

 

We envision the intellectual discipline of geoscience as a dynamic tetrahedron. Its volume includes the Earth system as a whole. Its six edges connect the four vertices:  the rock record, the solid Earth, the fluid Earth, and the living Earth. Below are some examples of current research projects.

Graduate student Matthew Kogle (right) and recent graduate Kelly Hoehn (left) meet in Weeks Hall to discuss locations in southern Wisconsin that were visited as part of the USArray program. Kogle and Hoehn logged thousands of miles driving rural Wisconsin roads searching for appropriate locations and seeking permission from landowners to place the equipment on their property.
