An investigation of avoidance by Antarctic krill of RRS James Clark Ross using the Autosub-2 autonomous underwater vehicle
of the research vessel by Antarctic krill Euphausia superba. The AUV was equipped with the same type ... measured the density of krill along transect acoustically (g m-2 wet mass) prior to the ship’s arrival. We ... hypothesised that if krill avoided the ship, perhaps in response to radiated noise, then the ship should detect ... less krill than the AUV (which is very quiet). We were unable to detect any significant difference ...
