Reducing uncertainty and bias in acoustic biomass estimations of southern blue whiting (Micromesistius australis) in the southeastern Pacific: transducer motion effects upon acoustic attenuation

We evaluated the loss of sensitivity due to the motion experienced by a hull-mounted transducer and its effects upon the estimated biomass of southern blue whiting (Micromesistius australis) in an acoustic survey conducted in the southeastern Pacific, off the Chilean coast, during the austral winter...
