Abstract

To ensure safety of navigation, the monitoring of high-risk seabed areas is one of the primary tasks of the hydrographic activity. Monitoring of these areas also provides insights into environmental and scientific applications. The Graham Bank (Strait of Sicily in the Mediterranean Sea) has been monitored by the Italian Hydrographic Institute (IIM) for over a century. This article describes the IIM monitoring of the Graham Bank by conducting surveys using techniques and technologies available at each time and integrating all of the data into a modern bathymetric database. Based on the outcomes of this case study, the IIM proposes ways to minimize the risk to vessels passing close to the Graham Bank.
