The aqueous search for objects covered by sediment is a common and challenging problem. Here we outline a sequential methodology for the assessment of targets identified by sub-bottom profiling. This comprises desktop study of available data; background hydrological information gathering (bathymetry, sediment cover, water chemistry); acoustic sub-bottom imaging (water penetrating radar, sonar); geolocation and probing of sub-bottom anomalies; deployment of suitable scent dogs. This procedure creates a hierarchy of targets for examination by dive teams and thence recovery.
