Khufu ship carbon dating
The surveying of the wreck site coincides with the deliberate sinking of two decommissioned Portuguese warships to create artificial reefs.
Local authorities are hoping to make Portimao a diving tourism site and the warships, which will eventually be joined by two more ships, into an underwater diving resort.
For nearly a century and a half, an Egyptian obelisk has graced the Victoria Embankment along the Thames River in London.
Last week, archaeologists began dive operations on a wreck in the Arade River near Portimao, Portugal.Engineers and archaeologists have successfully raised a 600 year old sailing cog from the depths of the Ijssel River in the Netherlands.The 55 ton vessel, along with a barge and punt, had been deliberately sunk to alter the flow of the river to make it more navigable and easier for ships to dock on the Ijssel’s banks.Archaeologists are hoping to learn more about Portimao’s role in Roman trade routes.Dives are also planned to wrecks discovered in the 1990’s that are believed to be Spanish ships from the 17th century.
