The world's oceans, seas, and rivers are filled with relics of the past. These shipwrecks are like snapshots of history, frozen in time in the murky depths. Underwater archeologists study them to get a better understanding of our historical heritage. Laura's guests are David Switzer, retired Professor of History at Plymouth State University and also consulting Nautical Archeologist for the state of New Hampshire, and Brendan Foley, Postdoctoral Fellow specializing in Archeology in Deep Water at the Woods Hole Oceanographic Institution in Massachusetts and lecturer in the history of technology at M.I.T.
