Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
solution. We apply the method to reconstruct maps of distribution of Antarctic krill throughout areas 100 x ... approximately 1600 observed data. We inferred krill density for all 32000 0.5 x 0.5 km cells in the area. The ...
