1. ESTIMATION OF MANAGEMENT REFERENCE POINTS CONSISTENT WITH THE CATCH TRIGGER LEVEL FOR THE ANTARCTIC KRILL FISHERY IN AREA 48

   Abstract:  The Generalised Yield Model was used to estimate fishing mortality and spawning stock biomass reference points for the krill fishery in CCAMLR Area 48 consistent with the catch trigger level of 620,000 tonnes. Projections were run with various increased levels of recruitment variability

2. USING ECOSYSTEM STRUCTURE TO IDENTIFY FINER-SCALE SSMUS FOR OCEANIC AREAS IN SUBAREAS 48.1 TO 48.3

   Abstract:  One of the main issues in the management of the krill fishery is finding a spatial subdivision of catches that allows CCAMLR to achieve its objectives for both the fishery and the ecosystem. This requires a framework of spatial areas over which catches can be subdivided. WG-EMM has

3. VARIABILITY IN KRILL BIOMASS LINKS HARVESTING AND CLIMATE WARMING TO PENGUIN POPULATION CHANGES IN ANTARCTICA

   Abstract:  The West Antarctic Peninsula (WAP) and adjacent Scotia Sea support abundant wildlife populations, many of which were nearly extirpated by humans. This region is also among the fastest-warming areas on the planet, with 5–6 °C increases in mean winter air temperatures and associated

4. ADÉLIE PENGUIN SURVIVAL: AGE STRUCTURE, TEMPORAL VARIABILITY AND ENVIRONMENTAL INFLUENCES

   Abstract:  The driving factors of survival, a key demographic process, have been particularly challenging to study, especially for winter migratory species such as the Adélie penguin (Pygoscelis adeliae). While winter environmental conditions clearly influence Antarctic seabird survival, it has

5. WILL KRILL FARE WELL UNDER SOUTHERN OCEAN ACIDIFICATION?

   Abstract:  Antarctic krill embryos and larvae were experimentally exposed to 380 (control), 1000 and 2000 μatm pCO2 in order to assess the possible impact of ocean acidification on early development of krill. No significant effects were detected on embryonic development or larval behaviour at 1000

6. OCEAN-BOTTOM KRILL SEX

   Abstract:  For the first time the entire sequence of the mating behaviour of Antarctic krill (Euphausia superba) in the wild is captured on underwater video. This footage also provides evidence that mating can take place near the seafloor at depths of 400–700 m. This observation challenges the

7. COLLAPSE OF SOUTH AFRICA’S PENGUINS IN THE EARLY 21ST CENTURY

   Abstract:  The number of African penguins Spheniscus demersus breeding in South Africa collapsed from about 56 000 pairs in 2001 to some 21 000 pairs in 2009, a loss of 35 000 pairs (>60%) in eight years. This reduced the global population to 26 000 pairs, when including Namibian breeders, and

8. Summary of the work of the CEP on Marine Protected Areas

   Abstract:  At CEP XIV (2011), the Antarctic Treaty Secretariat presented Secretariat Paper 6   “Summary of the Work of the CEP on Marine Protected Areas”. This paper reports on the development of the topic of Marine Protected Areas (MPA’s) in discussions of the Committee for Environmental

10. A balanced trophic model of the ecosystem of the Ross Sea, Antarctica, for investigating effects of the Antarctic toothfish fishery

    Abstract:  We report on the development of a mass balanced carbon-budget trophic model of the Ross Sea with which to investigate effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). A survey of the available literature provided an initial set of parameters describing the abundance
