Distribution patterns and biomasses of Antarctic krill (Euphausia superba) and ice krill (E. crystallorophias) with note on distribution of Antarctic minke whales (Balaenoptera bonaerensis) in the Ross Sea in 2005
Abstract: Distribution patterns and biomasses of Antarctic and ice krill in the Ross Sea in ... austral summer in 2005 were studied using a multi-disciplinary survey data set combining cetacean, krill ... obtained from samples of RMT hauls and stomach contents of Antarctic minke whales. Ice krill was ... distributed on the continental shelf region (shallower than 1000m water depth). In contrast, Antarctic krill ...

MaxEnt reconstructions of krill distribution and estimates of krill density from acoustic surveys at South Georgia 1996–2000
Abstract: We present Maximum Entropy (MaxEnt) reconstructions of krill distribution and estimates ... of mean krill density within two survey boxes of dimensions 80 km x 100 km to the north east and ... gathered in the boxes in austral summers 1996 – 2000. Krill densities had previously been determined at ... 1600 krill density estimates per box. The MaxEnt technique uses a Bayesian approach to infer the most ...
