Effects of orientation on acoustic scattering from Antarctic krill at 120 kHz
. superb a DWBA scattering model is proposed that is scalable by animal length. With good orientation ... approximation (DWBA) method were developed for five animals and compared with the measurements. Both measured ... and modeled scattering patterns showed that 120 kHz acoustic scattering levels are highly dependent on ... animal orientation. Use of these scattering patterns with orientation data from shipboard studies of E ...

Genetic structuring of Patagonian toothfish populations in the southwest Atlantic Ocean: the effect of the Antarctic Polar Front and deep-water troughs as barriers to genetic exchange
species with potential for high dispersal are of great interest, not only from an evolutionary standpoint ... but also with regard to effective management. Previous genetic studies have demonstrated substantial ... these data indicate that the APF, as a barrier to larval dispersal, is the major inhibitor of genetic ... exchange between toothfish populations, with deep-water troughs and distance between sites contributing to ...
