The Bergen Echo Integrator (BEl) is a software system designed for convenient postprocessing of echo sounder data. BEl is realized in international standards and is essentially machine independent. Development of BEl for analysis of such diverse scatterers as plankton, pelagic fish, bottom fish and bottom itself is reviewed. The system design is described and the latest advances are discussed. Among these: a more flexible database, an improved man-machine interface, an easier procedure for accessing data and a system for mapping the data. General operating procedures are described for extraction of information while scrutinizing acoustical data.
