Deep Science

We host world-leading experiments deep underground, seeking answers to some of the most profound mysteries of the universe.

World class Underground Research at SURF

Scientists study mysterious particles like neutrinos and dark matter deep underground where a mile of rock shields experiments from cosmic radiation that constantly bombards Earth. We also host biologists, geologists, and engineers, too.
