Advances in Bergen Echo Integrator
Original version
This report is not to be cited without prior reference to the authorAbstract
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.
