In 2016, Tara Roberts was living in Washington D.C. and working at a nonprofit when she visited the National Museum of African American History and Culture and a photograph she saw there changed her life. The image was of Black scuba divers from the group Diving with a Purpose which searches for and documents slave shipwrecks around the world. Roberts quit her job, learned to scuba dive and chronicled the work of these scuba divers. Her book about that journey is “Written in the Waters: A Memoir of History, Home and Belonging.”
