Some comments on the procedure for testing estimators of krill abundance which utilise survey data
Abstract: Since krill distributional data do show evidence of spatial correlation, estimators ... performance in practice. Such studies require a simple method for computer generation of krill distribution ... " models of krill distribution are considered. These achieve overall spatial correlation by placing ... krill swarms at random within larger aggregation features termed concentrations; these concentrations ...

Acoustic data analysis and models of krill spatial distribution
used in three descriptors of krill spatial aggregation: power spectra for krill biomass fluctuations ... in space, semivariogram (spatial autocorrelation of krill biomass) and the frequency distribution of krill ... . The computed frequency distribution of krill biomass is bimodal and appears to be the mixture of two lognormal ... of data analysis suggest that krill patch size or rather a basic swarm size should be smaller that 200 ...
