1. DEVELOPING FOUR PLAUSIBLE PARAMETERISATIONS OF FOOSA (A SO-CALLED REFERENCE SET OF PARAMETERISATIONS) BY CONDITIONING THE MODEL ON A CALENDAR OF EVENTS THAT DESCRIBES CHANGES IN THE ABUNDANCES OF KRILL AND THEIR PREDATORS IN THE SCOTIA SEA

   Abstract:  We tuned four parameterizations of Foosa to provide predictions that are consistent with the agreed calendar, as specified by the WG-SAM, that describes changes in the abundances of krill and their predators in the Scotia Sea. First, we compiled a set of base parameterizations from

2. THE ANTARCTIC KRILL AND ECOSYSTEM SURVEY WITH R/V “G. O. SARS” IN 2008

   Abstract:  This report describes the multipurpose AKES survey (Antarctic Krill and Ecosystem Studies) carried out with R/V G. O. Sars, 4.01-27.03.08, including some selected results. The main purposes for the AKES project were to • evaluate the links between the krill resources and distribution in

3. IN SITU MEASUREMENTS OF TILT ANGLE DISTRIBUTION AND TARGET STRENGTH IN ANTARCTIC KRILL (EUPHAUSIA SUPERBA)

   Abstract:  Knowledge of the scattering properties of Antarctic krill (Euphausia superba) is crucial for biomass estimates of the species, but in situ investigations regarding this are still very scarce. We conducted a field study in the Southern Ocean where one of the objectives was to acquire data

4. A RISK ASSESSMENT TO ADVISE ON STRATEGIES FOR SUBDIVIDING A PRECAUTIONARY CATCH LIMIT AMONG SMALL-SCALE MANAGEMENT UNITS DURING STAGE 1 OF THE STAGED DEVELOPMENT OF THE KRILL FISHERY IN SUBAREAS 48.1, 48.2, AND 48.3.

   Abstract:  We used Foosa and the reference set of parameterizations developed by Watters et al. (2008) to assess the risks and tradeoffs associated with various management strategies for subdividing the precautionary krill catch limit among SSMUs in Area 48. Our methodological approach follows

5. A PRELIMINARY BALANCED TROPHIC MODEL OF THE ECOSYSTEM OF THE ROSS SEA, ANTARCTICA, WITH EMPHASIS ON APEX PREDATORS

   Abstract:  We report on the development of a mass balanced carbon-budget trophic model of the Ross Sea as a step towards investigating ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model has 30 trophic groups representing all the major biota of the Ross Sea.

6. TROPHIC OVERLAP OF WEDDELL SEALS (LEPTONYCHOTES WEDDELLI) AND ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) IN THE ROSS SEA, ANTARCTICA

   Abstract:  We present information to investigate the significance of Antarctic toothfish as a prey item for Weddell seals in the Ross Sea. • We summarise the life history of Weddell seals to provide an overview of their use of the Ross Sea. As consumption of prey by Weddell seals (both the amount

7. CONDITIONING SMOM USING THE AGREED CALENDAR OF OBSERVED CHANGES IN PREDATOR AND KRILL ABUNDANCE: A FURTHER STEP IN THE DEVELOPMENT OF A MANAGEMENT PROCEDURE FOR KRILL FISHERIES IN AREA 48

   Abstract:  The updated version of the Spatial Multi-species Operating Model (SMOM) of krill-predator-fishery dynamics described in an accompanying paper is conditioned using the WG-SAM set of reference observations for Area 48 (the SAM calendar). Results are presented for two implementations of

9. INCOMPLETE SEARCH EFFORT AS A POTENTIAL SOURCE OF BIAS IN BROAD-SCALE ESTIMATES OF PENGUIN ABUNDANCE DERIVED FROM PUBLISHED COUNT DATA: A CASE STUDY FOR ADÉLIE PENGUINS IN EAST ANTARCTICA

   Abstract:  Potential Adélie penguin breeding habitat (defined as ice-free land with area >4000 m2 and within 500 m of the ocean) in the Australian Antarctic Territory (AAT) was mapped using a GIS, and the literature reviewed for evidence of the mapped habitat being searched for occupation by

10. ANTARCTIC FUR SEAL PUP PRODUCTION AND POPULATION TRENDS IN THE SOUTH SHETLAND ISLANDS WITH SPECIAL REFERENCE TO SOURCES OF ERROR IN PUP PRODUCTION ESTIMATES

    Abstract:  This paper reports the results of a ground survey of fur seal colonies from in the South Shetland Islands in 2007/08. Multiple counts of pups at each colony were conducted to establish confidence limits on pup production. Total pup production was 7,602 (±103) pups down 24.4% from the
