1. 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

2. OCCURRENCE OF DWARF MINKE WHALES (BALAENOPTERA ACUTOROSTRATA SUBSP) AROUND THE ANTARCTIC PENINSULA

   Abstract:  The occurrence of dwarf minke whales (Balaenoptera acutorostrata subsp.) around the Antarctic Peninsula was examined based on 406 sightings of minke whales recorded during the Chilean Antarctic Scientific Expeditions and other opportunistic cetacean surveys. Identification of the species

3. DISCRIMINATION OF ENVIRONMENTAL VARIABLES THAT INFLUENCE THE CATCH PER UNIT EFFORT: THE CASE OF THE ANTARCTIC KRILL FISHERY

   Abstract:  The use of the catch per unit effort (CPUE) as an index of abundance usually requires a standardization process consisting of isolating all those exogenous factors from temporal variations in abundance from the CPUE time-series. These exogenous factors include those generated by

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. Research plan for toothfish in Divisions 58.4.4a and b by Shinsei Maru No. 3 in 2011/12

   Abstract:  A tagging survey in SSRUs B and C in Division 58.4.4 a & b was initiated in the 2010/11 fishing season with the aims of providing the data required for assessments of the population structure, size, movement and growth of Dissostichus spp. in the centered area of Division 58.4.4 a

9. Principles for evaluating data collection plans in data-poor exploratory fisheries

   Abstract:  Since 1992, CCAMLR has agreed that exploratory fishing is not to be allowed to expand faster than the acquisition of information necessary to ensure that the fishery can and will be conducted in accordance with the principles set forth in Article II of the Convention. However, several

10. 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
