Echoview Software acknowledges Ken Foote and other researchers at the IMR in Norway for their pioneering work on post-processing of echosounder data (Foote, K.G., Knudsen, H.P., Korneliussen, R.J., Nordbø, P.E. and Røang, K. 1991. Postprocessing system for echo integrator data. J.Acoust. Soc. Am., 90, 37-47.).

Echoview Software acknowledges the great assistance provided to us by the early adopters of Echoview and in particular we would like to thank Dave Demer, Roger Hewitt, John Simmonds, Dave MacLennan, Paul Fernandes, Mike Soule and Manuel Barange for their faith in our abilities and their willingness to work with the very early versions of Echoview.

Dr Manuel Barange and Gareth Lawson, of South African Sea Marine and Coastal Management, are acknowledged for providing SHAPES algorithms, used to identify schools and calculate parameters of regions defined with the School Detection module. Partial funding for his work was provided by VIBES, a research initiative between Sea Fisheries (South Africa), the University of Cape Town and Orstom (France).

William Michaels and Michael Jech at NOAA/NMFS Northeast Fisheries Science Center in the USA for providing us with the data for the file demodata.ek5, used as the default file for our EK500 simulator.

Echoview users around the world who have taken the time to test Echoview, provide feedback and request enhancements. Your efforts have been essential to the development of Echoview—Thank you!
