Size and stage composition of age class 0 Antarctic krill (Euphausia superba) in the ice-water interface layer during winter/early spring
Abstract: The condition and survival of Antarctic krill (Euphausia superba) strongly depends on ... developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains largely ... unknown. The aim of this study was to improve the understanding of the krill's interaction with the ... sea ice habitat during winter/early spring by conducting large-scale sampling of the ice-water ...

A quantified Bayesian maximum entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the 2000 CCAMLR survey
Abstract: We present the results of an alternative method of estimating krill abundance, and ... producing maps of krill distribution, from the data collected during the 2000 CCAMLR survey of the Scotia ... unsurveyed off-transect portions of the survey area were found by interpolation, and thus values for total ... inferred. The MaxEnt formalism allows an objective choice of the parameters of the interpolation, and hence ...

A distribution-free model of length-frequency distribution to inform fishery stratification for integrated assessments
Abstract: Length frequency distributions (LFD) of catch collected as a random sub-sample from ... /or gear specific selectivity. A distribution-free model of LFD is described which is fitted to the ... set of length quantiles L for a predetermined set of corresponding probabilities P (in this instance ... 0.05, 0.1 to 0.9 in 0.1 increments, and 0.95), constructed from individual length measurements of ...

Here we report on the successful use of micro geolocation logging sensor ... tags to track the movements, and activity, of four leopard seals for trips of between 142-446 days ... advance in our limited knowledge of leopard seals. We show the longest periods of tracking of leopard ... island of South Georgia. It appears that these tracked animals migrate in a directed manner towards Bird ...
