2. DISTRIBUTION AND ABUNDANCE OF ANTARCTIC TOOTHFISH IN THE ROSS SEA

   Abstract:  This report is a synthesis of mostly existing information which has been compiled for the purposes of addressing items on the FEMA 2 agenda. It summarises the management of the fishery, catch and effort, size distribution, and tagging data collected from the Antarctic toothfish fishery

3. CIRCULATION IN THE ROSS SEA SECTOR OF THE SOUTHERN OCEAN: REPRESENTATION IN NUMERICAL MODELS

   Abstract:  The circulation in the Ross Sea sector of the Southern Ocean is examined in three numberical models of intermediate to high resolution. Despite the model differences (including physics, forcing) the circulation representation is relatively consistent, both in terms of the mean and some

4. A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA

   Abstract:  We present a quantitative food web of the Ross Sea as a step towards investigating ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model consolidates quantitative information on trophic links across all the major biota of the Ross Sea and tests for

5. STRONG EFFECTS OF ENVIRONMENTAL CONDITIONS ON REPRODUCTIVE SUCCESS OF PENGUINS AT KING GEORGE ISLAND

   Abstract:  Generalized linear and additive models suggest that large proportions of inter-annual variability in the reproductive success of Adélie, gentoo, and chinstrap penguins can be explained by simple linear predictors based on local weather conditions and winter sea ice extent. Local weather

6. PROPERTIES OF WATER DYNAMICS AND KRILL DISTRIBUTION IN THE SOUTH SANDWICH ISLANDS SUBAREA

   Abstract:  of mean krill density in Subarea 48.4 there are premises for formation of the zones with increased density. These zones are located within the near-shore shelf-based SSMU and associated with meanders and eddy favorable for krill concentration. Here, in the cold water of the Weddell Sea,

7. KRILL DENSITY ESTIMATES IN CCAMLR SUBAREA 48.6 BASED ON ACOUSTIC DATA COLLECTED DURING JANUARY–MARCH 2008

   Abstract:  A multidisciplinary survey was conducted with the RV ‘G.O. Sars’ as part of the Antarctic Krill and Ecosystem Studies (AKES) from January to March 2008. Acoustical data were sampled continuously on six frequencies along one west-east and two south-north transects between latitudes 50 and

8. AREA PROTECTION AFFORDED TO CAPE SHIRREFF THROUGH CCAMLR AND THE ANTARCTIC TREATY

   Abstract:  Conservation Measure 91/02 (2004) affords protection of the Cape Shirreff CCAMLR Ecosystem Monitoring Program (CEMP) site. Cape Shirreff is also protected as ASPA 149 through the Antarctic Treaty. The management plans for Cape Shirreff are due for review by CCAMLR in 2009 and by the ATCM

9. KRILL CATCHES INDICATE THE IMPACT OF THE EL-NIŇO – SOUTHERN OSCILLATION RELATED PROCESSES ON THE DISTRIBUTION OF KRILL BIOMASS BETWEEN SUBAREAS OF THE ATLANTIC SECTOR OF ANTARCTIC

   Abstract:  This presentation addresses the need to incorporate recent studies aimed to identify different climate oceanographic regimes and its influence on krill biomass into the discussion of krill fishery management issues. Krill catch data in Subareas 48.1, 48.2 and 48.3 are compared to the

10. MODELING PREDATION BY TRANSIENT LEOPARD SEALS FOR AN ECOSYSTEM-BASED MANAGEMENT OF SOUTHERN OCEAN FISHERIES

    Abstract:  Correctly quantifying the impacts of rare apex marine predators is essential to ecosystem-based approaches to fisheries management, where harvesting must be sustainable for targeted species and their dependent predators. This requires modelling the uncertainty in such processes as
