Since the 1960s, scientific deep-sea core sampling has given scientists tremendous insights into Earth's interior and its history. The international effort to recover rocks from deep under the ocean floor continues in places like the Bay of Bengal, where UW Tacoma faculty member Peter Selkin spent two months at sea in 2015. Find out what it's like to be on a deep-sea scientific drilling expedition, and what we hope to learn by looking under the seafloor. Dr. Peter Selkin is an associate professor in Science and Mathematics at UW Tacoma, where he teaches physics and geoscience. He and his students use magnetism and magnetic materials to study Earth's history and deep time.
