Acoustic seafloor classification
article
Acoustic seabed classification is becoming increasingly important for many fields, including marine geology, hydrography and navigation, coastal engineering, environmental sciences, marine biology and fisheries. The main advantages over conventional bottom grabs are the continuous, non-invasive probing of the seabed and a vast reduction in survey time and costs. The difficulty of acoustic methods is associated with complicated acoustic wave scattering off the rough and layered seabed, which makes interpretation of the received signals cumbersome. In other words: how do we retrieve bottom type from the echo characteristics? This is why acoustic seabed classification is still the subject of extensive research.
