4. Using vessel acoustics to detect diving patterns of krill foraging predators automatically: Development of a novel method for quantifying impact of krill fishing on seals and penguins

   Abstract:  The aim of this work was to assess the possibilities of automatically generating a ... of diving predators in the data is feasible. A relatively low detection probability of our algorithms ... compared to the manual detections, suggest that there is significant room for improvement. Given the ... caveats of an imperfect methodology, the results document the possibilities to automatically extract, with ...
