SACLAF – Acoustic System for Automatic Seafloor Classification 22 March 2018 Subsea Tech has developed in partnership with Seaviews company an Acoustic System for Automatic Seafloor Classification (SACLAF) using a multibeam echosounder. This project was led within the framework of the ADEME’s Programme Investissement d’Avenir (with the contribution of the Pôle Mer Méditerranée). The developed system allows measuring and classifying the variations of the sounder signal in order to determine the seafloor nature and the presence of marine vegetation (Posidonia, Eelgrass, Cymodocea). By implementing this technology, detailed and high resolution maps can be produced for large areas at low cost. Sonar and aerial images can be combined to cross-check the data.
