A quantified Bayesian Maximum Entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the CCAMLR-2000 Survey
intensity of each pixel in the reconstructed image corresponds to an estimate of krill density (g m–2) in ... from the CCAMLR-2000 Survey. Densities of almost 24 000 g m–2 were reported for individual 1 n mile2 ... regions, but only 0.8% of measurements exceeded 1 000 g m–2, and two-thirds were under 10 g m–2 (see ... Figure 2). Methods What is Maximum Entropy image reconstruction? Image reconstruction, in this case ...
