Although much work has been done over the past 60 years to investigate the underwater archaeological remains in the Venice Lagoon, often the findings lack high-resolution mapping and positioning. The recent application of high resolution multibeam echosounder and sub-bottom profi ler, not only allows for paleoenvironmental reconstruction, but it also provides new evidence of the presence of archaeological structures both over and within the seafloor. Th e new extensive mapping together with selective video inspections support a new interpretation and quantitative description of underwater and buried structures. The new maps represent the starting point for a reinvigorated eff ort to discover, document, and preserve the highly valuable underwater archaeological heritage in the Venice Lagoon.
