Exploration and identification of ancient Roman shipwreck located at Quseir, Red Sea

Abstract

Recent marine geophysical investigations in front of the Myos Hormos Port (also known as Quseir al-Qadim) on the Red Sea coast of Egypt indicated the existence of an ancient Roman shipwreck, among other features on the seafloor. The study showed that side scan sonar imaging is a powerful technique for classifying the seafloor and detecting submerged targets among other seafloor features with resembling acoustic signatures. Integrating bathymetric data with sonar imageries displayed the seafloor topography in front of the ancient port where reef habitats were dominant. The Autonomous Underwater Vehicle was efficient in mapping closed and near-shore areas like bays. This vehicle provided high-resolution bathymetric and sonar data for the semi-closed bay area located at the entrance of the ancient port. Acoustic measurements were done for the sunken shipwreck using sonar software, and a structural model was established for the ∼ 32 m long sunken ship. The model suggested the presence of a pile of shipload gathered around the shipwreck. Results can contribute to the development of Egypt's tourism industry by promoting underwater cultural heritage preservation, as the discovery of an ancient Roman shipwreck is a significant finding that can attract tourists worldwide.
