British Antarctic Survey, High Cross, Madingley Road, Cambridge CB3 0ET, England Comparison of geostatistical and random sample survey analyses of Antarctic krill acoustic data [Elektronische Daten] [A. W. A. Murray] Data from the acoustic surveys of MV SA "Agulhas” and FRV "Walther Herwig”, and the 1981 RRS "John Biscoe” South Georgia acoustic survey were analysed by geostatistical methods. Estimates of mean density (g m−2) of krill and their variances are compared with published results from statistical analyses based on random sampling theory. A further high-resolution geostatistical analysis of the MV SA "Agulhas” (ping-by-ping) data set of the density of each individual aggregation is also presented. These analyses illustrate the problems of applying geostatistical methods to data from highly aggregated species which can show marked skewness in their histogram of density. © 1996 International Council for the Exploration of the Sea Regular Articles nationallicence acoustic survey design nationallicence Antarctic krill biomass nationallicence geostatistics nationallicence spatial pattern nationallicence stock assessment nationallicence ICES Journal of Marine Science Oxford University Press 53/2(1996-04), 415-421 1054-3139 53:2<415 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0058 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0058 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Murray A.
