1. Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins

   Abstract:  1. Estimating food consumption is central to defining the ecological role of marine predators. This study developed an algorithm for synthesizing information about physiology, metabolism, growth, diet, life history and the activity budgets of marine predators to estimate population

2. The krill fishery observer manual – points to be revised

   Abstract:  This document lists up the current form to be filled in the observer manual for the krill fishery. I raise the underlying problem to be clarified or modified. This includes technical problems, workload limit, and also the problem of the commercial confidentiality. The current manual

3. Results of an acoustic investigation of Antarctic krill, Euphausia superba, biomass-density in the Elephant Island area in January/February 2001

   Abstract:  Results from an acoustic krill survey in the Elephant Island Area carried out Jan 27th to Feb 4th 2001 are presented. Data were collected with a SIMRAD EK60 Scientific Echo Sounder installed on the R/V “Polarstern”. The collected acoustic data were post-stratified in three strata based

4. Design of the Italian acoustic survey in the Ross Sea for the Austral summer 2003/04

   Abstract:  In agreement with the Report of the IXX WG-EMM (Art. 2.78; p.128), the current paper presents the next Italian survey, that will be carried out in the Ross Sea during the austral summer 2003-2004. The research consists of three core activities: (1) Acoustic sampling on krill (E. superba

6. Krill of the Ross Sea: distribution, abundance and demography of Euphausia superba and Euphausia crystallorophias during the Italian Antarctic expedition (January–February 2000)

   Abstract:  Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography of krill in the western Ross Sea (Antarctica). A midwater sampler-trawl (Hamburg Plankton Net) was

8. Spatial and temporal variability in foraging patterns of krill predators at Signy Island and South Georgia

   Abstract:  While constrained by the requirement to feed their young, land-based marine predators act as central-placed foragers with movements between their breeding colony and their food resource. In a system where the distribution and abundance of prey is highly variable, foraging behaviour must

10. Estimating penguin populations using image analysis of colour aerial photography

    Abstract:  Penguin populations are potentially sensitive indicators of change in the Antarctic and sub-Antarctic and are used extensively to monitor changes in the marine ecosystem. Aerial photographic surveys may provide the most robust method for estimating breeding population size, particularly
