New technology uncovers the underwater past
Swedish Radio News reports that the discovery of three major 17th century shipwrecks in the past year are due to the use of new technology. Johan Rönnby, professor in Marine Archeology at Stockholm’s Södertorn University calls it a “wreck boom”.
He says he hopes advanced technology will uncover more treasures from the past, and he looks forward to what could be learned from a ship from the Bronze Age.
The three discoveries were all relatively well-preserved in the slightly salty waters of the Baltic. They are the royal ship “Resande man”, the admiral’s flagship “Mars”, and the warship “Svärdet”.
The underwater archaeologists are using cameras with improved resolution that can take three dimensional images of the seabed. The technique provides the scientists with instant measurements that would otherwise have to laboriously made with rulers and printed photos.
