Summary
Antarctic biomass acoustic surveys generally yield biomass estimations expressed in terms of krill biomass, on basis of its being the major component of the Antarctic ecosystem. The influence of other scatterers is often left aside, thus introducing a bias in the estimations. The correlation between krill density distribution, as assessed by trawls, and Mean Volume Backscattering Strength frequency distribution in the range (-80, -60) dB(m−1·sr−1), allows to propose a method to reduce the bias. This method could be used to study the influence of each kind of scatterers on the recorded acoustic values, thus leading to better estimations.
