Deep under the ocean, enormous tectonic plates push against one another and spread apart. Shawn Wei, a doctoral student and McDonnell Scholar at Washington University in St. Louis, wants to understand what's really going on down there. Deep in the Pacific Ocean, how do rock, magma, and water interact? To find out, Wei analyzed data collected at the famous Lau Basin, one of the most geologically active places on Earth - and his results surprised all the experts. Here, Shawn describes his discovery, his methods, and how science isn't always like what you seen in the movies.
