The use of CCAMLR Statistical Subareas 88.1 and 88.2 and Division 58.4.1 by Macquarie Island giant petrels
adult northern giant petrels (Macronectes halli), and two fledgling chicks of each species during the ... summer of 2005-06. Adults of both species spent time in areas under CCAMLR jurisdiction. Adult southern ... giant petrels spent 37% of their overall time at sea in statistical sub-area 58.4.1, and 14% in sub-area ... incubation. Northern giant petrels were tracked during chick rearing. While 3 of four tracked birds did not ...

Modelling growth of Antarctic krill: growth trends with sex, length, season, and region
Abstract: Growth trends of Antarctic krill with sex, length, season and region using over 10 ... years accumulation of instantaneous growth rate (IGR) measurements were modelled using a Linear Mixed ... Model (LMM). A model of inter-moult period (IMP) as a function of temperature, required to convert IGR ... this model was used to predict seasonal IMP using a model of the average sea-surface temperature ...

Dynamics of Antarctic penguin populations in relation to inter-annual variability in sea-ice distribution
Abstract: To investigate the role of sea ice cover on penguin populations we used principal ... component analysis to compare population variables of Adélie (Pygoscelis adeliae) and chinstrap (Pygoscelis ... population size remained stable, whereas that of chinstrap penguins decreased slightly. For neither species ... apparent inverse density-dependent relationship between the number of Adélie breeding pairs and the number ...

Semi-empirical acoustic estimates of krill biomass derived from simulated commercial fishery data based on single-frequency acoustics
fishing seasons. From these data we develop semi-empirical indices of acoustic biomass in a Generalized ... Linear Modeling framework. We correlate these estimates of biomass with acoustic estimates derived from ... Elephant Island and West Shelf Areas of the US AMLR survey grid. Cross-validation of acoustic estimates ... frequency of animals is skewed towards larger animals. We show that it is possible to develop semi-empirical ...
