An article in Scientific American looks at the work of Tracy Gregg, associate professor of geology, who is aboard the RV Atlantis on a month-long journey to the Galapagos Spreading Center exploring the shapes of underwater lava flows after they've cooled to discover if the lava eruptions in this region are related and if the eruptions are affected by a hotspot a few hundred miles to the east.
