The Ephorate of Underwater Antiquities, in collaboration with the American Woods Hole Oceanographic Institution, has completed the digital underwater surveying and dimensional precision display of the Shipwreck of Antikythera. Last year’s imprinting pinpointed the exact shipwreck site of the vessel that carried the Antikythera Mechanism. However, the proximity of other findings such as anchors and amphorae from the same era made archaeologists consider the possibility that there was a second cargo vessel that accompanied the original ship. Therefore it became imperative to map a wider area of 350X45 meters approximately. Archaeologists now can put all the findings together and draw conclusions about the possible relationship between the two wreck positions. The detailed mapping creates a clearer picture of the relationship between the two sites, while the placement of the findings in the now imprinted area enhances the understanding of all the findings in the two positions. The mapping was done by a specialized team of the University of Sydney using the autonomous underwater vehicle Sirius. Resources for the investigation/excavation were provided by the Woods Hole Oceanographic Institute, American, European and Greek organizations, to meet the needs in qualified technical and scientific personnel. The Catherine Laskaridis Foundation contributed greatly by offering the vessel that was used as the basis of the research team. The Ephorate of Underwater Activities and its partners will continue research at the end of the summer season. The Antikythera shipwreck research is conducted on a five-year plan.
