Comparison of geostatistical and random sample survey analyses of Antarctic krill acoustic data
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 statistic...
