Professor Lucy Blue chats with maritime archaeologist, Dr Daniel Pascoe about discovering the 17th century 70-gun warship, the HMS Edgar.  Dan explains how a combination of boundless determination, in-depth archival research and geophysical investigations helped identify mounds that appeared to be the remains of the ship blown apart by sloppy storage of gun powder.  By probing these mounds and digging test pits Dan and his team uncover artefacts and human remains that identified them as remains from the Edgar and the crew who went down with it.
