It’s midnight. Kayla Goforth and her research assistants have been traveling by car, boat and even golf cart for some seven hours to get to Bald Head Island — but the work is just beginning. They get into a utility task vehicle and head to their field site: the nest of a loggerhead sea turtle. A biology doctoral student in Ken Lohmann’s lab at Carolina, Goforth studies the magnetic orientation of loggerhead sea turtle embryos. Scientists already know that sea turtles navigate using a sense called magnetoreception, allowing them to detect slight fluctuations between Earth’s magnetic fields at different latitudes and longitudes.
