Reducing uncertainty and bias in acoustic biomass estimations of southern blue whiting (Micromesistius australis) in the southeastern Pacific: transducer motion effects upon acoustic attenuation Reduciendo el sesgo e incertidumbre de las estimaciones hidroacústicas de biomasa de merluza de tres aletas (Micromesistius australis) en el Pacífico suroriental: efectos del movimiento del transductor sobre la atenuación acústica

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...
