Classification of Southern Ocean krill and icefish echoes using Random Forests
two or more echosounder frequencies. For commonly used frequencies, however, the differences for krill ... icefish are currently surveyed using bottom-trawls, but the resultant estimates of abundance may be biased ... because of the species’ semi-pelagic distribution. An acoustic estimate of the pelagic component of the ... population could indicate the magnitude of this bias, but first a reliable target identification method is ...
