Abstract

Underwater archaeological heritage is exposed not only to natural environmental stresses, but also is threatened by

human activity. As a matter of fact, both commercial fishing and recreational diving have caused considerable damage

toseveralmajorwrecksinthenorthernAdriaticSea.TheArchaeological Superintendence ofFriuliVeneziaGiuliaand

of Veneto have thus initiated an interdisciplinary collaboration with the University of Udine, involving the Department

of History and Preservation of Cultural Heritage, and the Department of Electrical, Management and Mechanical

Engineering, in order to develop a project that has as its primary objective the protection of underwater sites by both

surfaceandunderwatervideosurveillance.ItwasalsodecidedtostartanexperimentaltrialonthewrecksCaorle1and
