1. Workshop Report – The Ross Sea: Science, Policy and the Public in a Pristine Marine Ecosystemt

   Abstract:  Waters overlying the Ross Sea continental shelf and slope comprise slightly more than 3% of the Southern Ocean, which is inconsequential, yet its attributes, as identified in this workshop, coincide closely with the criteria agreed to by the UN Convention for Biological Diversity to

2. Antarctic toothfish and macrourids are likely important prey of Arnoux’s beaked whales in the Ross Sea region

   Abstract:  On the basis of circumstantial evidence, an elevated likelihood exists that Antarctic toothfish and the most-caught by-catch species, macrourids, in the Area 88 fishery are important components in the diet of the Arnoux’s beaked whale (Berardius arnouxii), which is a component of the

3. THE DIET OF THE ANTARCTIC TOOTHFISH IN THE ROSS SEA

   Abstract:  This brief review documents the species composition of prey consumed by the Antarctic toothfish, Dissostichus mawsoni, in the Ross Sea. The diet for a sample from McMurdo Sound in the southwestern Ross Sea indicates that fishes, especially Pleuragramma antarcticum, and mysids dominate

4. CHINSTRAP PENGUINS: MISUNDERSTOOD AND VULNERABLE MONITORS OF ECOSYSTEM CHANGES IN THE SCOTIA SEA REGION OF ANTARCTICA

   Abstract:  Sea ice plays a critical role in structuring ecosystem dynamics throughout the Scotia Sea (SS) region, and variations in ice extent are hypothesized to affect predator populations in this area directly. A paradigm guiding recent research in the Western Antarctic Peninsula (WAP) region of

5. CHARACTERISING KRILL FISHERY DYNAMICS USING A RANDOM WALK MODEL

   Abstract:  Krill fishery dynamics was analysed by using Fine-scale haul-by-haul data. Between-haul-distances were well described by a Levy Flight type random walk model. The inferred distribution pattern of fishable target concentrations showed differences between Subareas with targets in Subarea

6. JAPANESE SCIENTIFIC OBSERVER ACTIVITIES FOR KRILL FISHERY IN CCAMLR CONVENTION AREA FROM 2003/04 TO 2007/08 FISHING SEASONS

   Abstract:  This document introduces the recent activities and outcome of Japanese scientific observers onboard the commercial krill fishing vessel from 2003/04 to 2007/08 fishing seasons. Main fishing grounds of the Japanese fishery were the Subareas 48.1, 48.2, and 48.3. Recent observation effort

7. INTEGRATING COUNT EFFORT BY SEASONALLY CORRECTING ANIMAL POPULATION ESTIMATES (ICESCAPE): A METHOD FOR ESTIMATING ABUNDANCE AND ITS UNCERTAINTY FROM COUNT DATA USING ADÉLIE PENGUINS AS A CASE STUDY

   Abstract:  This work describes a parametric bootstrap model (Davison and Hinkley 1997) for standardising animal count data to a common reference point of breeding chronological for species showing temporal availability to sampling methodology. ICESCAPE (Integrating Count Effort by Seasonally

8. CLIMATE CHANGE AND THE ANTARCTIC MARINE ENVIRONMENT: MANAGEMENT IMPLICATIONS

   Abstract:  This paper discusses some of the implications of climate change and how these concerns necessitate that CEP and CCAMLR address a number of key issues if both organisations are to fulfil their international obligations. We suggest that in order for CEP and CCAMLR to undertake their

9. POPULATION ASSESSMENTS OF GENTOO PENGUINS (PYGOSCELIS PAPUA) BREEDING AT AN IMPORTANT ANTARCTIC TOURIST SITE, GOUDIER ISLAND, PORT LOCKROY, PALMER ARCHIPELAGO, ANTARCTICA

   Abstract:  Goudier Island is located in the Palmer Archipelago, to the west of the Antarctic Peninsula; it is one of the most frequently visited tourist sites in Antarctica. A number of gentoo penguin (Pygoscelis papua) breeding colonies are located on the island and these have been the focus of

10. PENGUIN RESPONSES TO CLIMATE CHANGE IN THE SOUTHERN OCEAN

    Abstract:  Penguins are adapted to live in extreme environments, but they can be highly sensitive to climate change, which disrupts penguin life history strategies when it alters the weather, oceanography and critical habitats. For example, in the southwest Atlantic, the distributional range of the
