i sistemi sonar per studiare i fondali marini e oceanografici: SideScan Sonar e SubBottom Profiler forniscono immagini ad alta e altissima risoluzione dei fondali, degli oggetti che vi giacciono, e di ciò che nascondono al di sotto. Presentazione tenuta a maggio 23 durante i Codevintec Days dal dott. Lorenzo Minno.
