Measurements of sound-speed and density contrasts of Antarctic krill (Euphausia superba) on board RV Kaiyo Maru
Abstract: In order to calculate the target strength of Antarctic krill (Euphausia superba) using ... -density contrasts between the animal and the surrounding water are required. Sound-speed and mass-density ... of krill were measured during the Antarctic surveys conducted by the Japanese RV Kaiyo Maru in 1999 ... density bottle method. The mean total length and the mean mass-density contrast were 43.5mm and 1.028 near ...

Variability in krill length distribution in 48.1 derived from data collected by scientific observers
Abstract: Information on the length distribution of krill in the catch, and the spatial and ... temporal patterns of krill length in the population is essential to assess krill population status and ... dynamics, and the impacts of a fishery on the stocks. Here, we use generalised additive models (GAM) and ... generalised additive mixed models (GAMM) to evaluate the spatial and temporal patterns of length in Antarctic ...

PRELIMINARY ESTIMATION OF PENGUIN BREEDING ABUNDANCE AT SPATIAL-SCALES OF RELEVANCE TO CCAMLR: INCORPORATING UNCERTAINTY IN COUNT DATA
Abstract: One recommendation from the Predator Survey workshop was the undertaking of some ... immediate inter-sessional work to be reported to WG-EMM-08. The work to be undertaken included preliminary ... Antarctic data for Adélie penguins. It was recognised that the abundance estimates would not be corrected ... for availability (e.g. nest failure) and hence would to some extent be biased estimates of the ...
