Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
allows the most efficient possible use of known data in the inference process. The method takes explicit ... account of spatial correlation in the observed data and seeks to reconstruct a distribution of density ... approximately 1600 observed data. We inferred krill density for all 32000 0.5 x 0.5 km cells in the area. The ... method is computationally demanding but appears to work well, even in cases when the distribution of ...
