Abstract
This study combines marine remote sensing and photogrammetry to investigate underwater cultural heritage (UCH) sites in the Gulf of Patras, Greece. The research utilized multibeam echosounders, side scan sonar, and marine magnetometers to detect potential UCH sites, followed by visual inspections using a remotely operated vehicle (ROV) equipped with a GoPro camera. Photogrammetry techniques were applied to create high-quality 3D models of the identified UCH site, revealing sunken cannons within a Posidonia oceanica meadow. Despite shape alteration caused by concretions and biological colonization, the 3D models provided valuable morphometric data. This integrated approach demonstrates the effectiveness of marine remote sensing and photogrammetry in mapping and documenting UCH sites, contributing to the preservation and exploration of underwater heritage. In addition, it demonstrates the need of detailed mapping of the costal marine environments in regard to protected habitats and potential archeological sites by providing a multi-platform approach. Advances in today's technology, has made it possible to acquire high quality visual and spatial data through the marine environment with relative ease. Surveying the ocean floor with a phenomenal amount of detail in the most cost-efficient way and highlighting targets of importance is a major key to underwater research. The coastal area of Achaia serves as the main area of focus in this current endeavor.
