Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
Abstract: We present a maximum entropy (MaxEnt) method for inferring stock density and mapping ... across the whole survey area that is both consistent with the observed data and for which the entropy is ... 80 km. Survey data were integrated at 0.5 km intervals along ten 80 km transects, giving ... approximately 1600 observed data. We inferred krill density for all 32000 0.5 x 0.5 km cells in the area. The ...
