Hydroacoustic data form almost the only basis for seabed imaging [1]. The accuracy of scanning devices is therefore crucial for the reliability of the images. In the paper, the precision of the Simrad EM3000 multibeam echosounder was examined by means of statistical methods on real data. The maximum and mean errors were estimated, the correlation of error(More)
This article presents a method developed for the estimation of measurement error values (and their distribution) that occur in the process of marine sounding by a multibeam echosounder. The method, based on real data obtained in a specific marine environment, yields much more precise information on measuring instrument accuracy. The author also describes(More)
