Documentation and Conservation of Underwater Cultural Heritage (UCH) is crucial to preserve humankind’s history and traditions, safeguarding tangible testimonies of past human life while ensuring its accessibility to present and future generations. TECTONIC project will promote an intersectoral collaboration between academic and non-academic professionals (such as technical experts, archaeologists, conservator, geologists, engineers, computer scientists) working in different topics related to the UCHs, to respond and find solutions to the complex issues still existing in the field of UCH.
