A quantified Bayesian maximum entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the 2000 CCAMLR survey
Abstract: We present the results of an alternative method of estimating krill abundance, and ... producing maps of krill distribution, from the data collected during the 2000 CCAMLR survey of the Scotia ... unsurveyed off-transect portions of the survey area were found by interpolation, and thus values for total ... inferred. The MaxEnt formalism allows an objective choice of the parameters of the interpolation, and hence ...
