Abstract: The LOG_a DSLP®-echosounder method describes a new innovative method for hydrographical surveying. The LOG_a DSL®-method is based on a new concept and is independent of utilized frequencies as well as independent of core sampling. Only the frequency-independent method makes it possible to proof the layer-interfaces and the material-stages “fluid and solid”. Because of this, the performance parameters of high resolution detection are 3 cm in field use, the reproducibility is better 99%. The physically proof of the sequence and thickness of individual suspensions-, transitions-and sediment layers are achieved. The LOG_a DSLP®-method was developed by General Acoustics Gmb H, Ottendorf, Germany. The performance of the LOG_aDSLP®-method is presented by various results from different locations of the North and Baltic seas. Suspensions and consolidated sediment layers with thickness less than 5 cm were be proven, as well as physically definite classifications of sediment layers have been made up to a depth of 25m below solid bottom.
