The world’s best known estuarine lagoon has historically importance for sheltering the City of Venice and is an ever-changing environment with only 8% covered by land, 12% by open water and the remaining 80% by mud flats, tidal shallows and salt marshes.

This geographical setting, hosting complex ecosystems, is influenced by tidal cycles entering through three sea inlets and freshwater and sediment supplied by river influx.

The Venice Institute of Marine Science (ISMAR-CNR) is engaged in research and monitoring projects of the lagoon.

Monitoring of changes to the environment is becoming ever more important with changing sea levels and as the human impact increases with the MOSE flood protection project enabling the closing of the sea inlets and dredging activities.

Kongsberg Geoacoustics has been was invited recently by the institute to demonstrate their technology for gathering high-resolution bathymetry data with the aim of effectively covering large very shallow water areas with portable installation, providing highly repeatable data to allow monitoring of even smallest changes through time.
