Marine archaeologists and a small army of scuba divers are working to uncover the stories behind sunken ships from the trans-Atlantic slave trade. Marketplace’s Kimberly Adams talks with Justin Dunnavant, an assistant professor of anthropology at the University of California, Los Angeles, and one of those divers, about how advances in technology are improving our ability to examine those ships and understand the history they represent.
