The Pilae of Nisida. Some geological and archaeological observations

This paper represents an interesting case of coastal landscape reconstruction by using innovative marine robotic instrumentation, applied to an archaeological key-site in the Campi Flegrei (Italy), one of the more inhabitant areas in the Mediterranean during the Roman period. The multidisciplinary study of the submerged Roman port at Nisida Island was aimed to reconstruct the natural and anthropogenic underwater landscape by elaborating a multiscale dataset. The integrated marine surveys were carried out by a marine drone foreseeing the simultaneous use of geophysical and photogrammetric sensors according to the modern philosophy of multi-modal mapping. All instrumental measurements were validated by on-site measurements performed by specialized scuba divers. The multiscale analysis of the sensing data allowed a precise reconstruction of the coastal morpho-evolutive trend and the relative sea level variation in the last 2000 years.
