Odyssey’s first big treasure discovery came in 2003 when they found the Civil War-Era shipwreck of the SS "Republic". An extensive archaeological excavation was conducted that included a pre-disturbance survey and around 2,500 underwater high-resolution images captured and used to create a photomosaic of the entire site. Over 51,000 gold and silver coins were recovered from the site as well as 14,000 artifacts. Six archaeological reports were written about the shipwreck project and two books were published, Lost Gold of the Republic and Bottles from the Deep. PBS and National Geographic also aired documentaries on the discovery.
