MaxEnt reconstructions of krill distribution and estimates of krill density from acoustic surveys at South Georgia 1996–2000
of mean krill density within two survey boxes of dimensions 80 km x 100 km to the north east and north ... interannual and regional (east box cf west box) differences in mean krill density, the MaxEnt approach seems ... to work well, providing plausible maps of distribution. The technique also yields mean krill densities ... We present Maximum Entropy (MaxEnt) reconstructions of krill distribution and estimates of mean ...
