3. An 8-year cycle in krill biomass density inferred from acoustic surveys conducted in the vicinity of the South Shetland Islands during the austral summers of 1991/1992 through 2001/2002

   Abstract:  Data from single and multi-frequency active acoustic surveys conducted annually in the vicinity of the South Shetland Islands, Antarctica were re-analyzed using updated procedures for delineating volume backscattering due to Antarctic krill, adjusting for signal contamination due to

4. Populations of surface-nesting seabirds at Marion Island, 1994/95 to 2002/03

   Abstract:  During the 1990s and early 2000s, populations of surface-nesting seabirds at Marion Island showed different trends, but for the majority of species numbers decreased. Reduced numbers of gentoo penguins Pygoscelis papua, eastern rockhopper penguins Eudyptes chrysocome filholi, Crozet

5. Decrease in numbers of the eastern rockhopper penguins Eudyptes chrysocome filholi at Marion Island, 1994/95 to 2002/03

   Abstract:  Numbers of rockhopper penguins Eudyptes chrysocome breeding at Marion Island decreased from about 173 000 pairs in 1994/95 to about 67 000 pairs in 2001/02. During 1994/95-2002/03 pairs fledged on average 0.40 chicks per annum, an amount thought insufficient to balance mortality of

6. Differentiated catchability of trawls as a method for a more precise estimate of density of krill swarms and its biomass

   Abstract:  Krill escapement in different parts of krill trawls and their differentiated catchability have been studied. It is shown that krill possesses behavioural peculiarities representing considerable importance for catching results. It is proved that the estimation of density and size

7. WG-EMM Subgroup on Protected Sites: Terms of Reference – summary of CCAMLR decisions

   Abstract:  The proposed terms of reference of the WG-EMM Advisory Subgroup on Protected areas are presented "in a manner that properly places the tasks in context" of CCAMLR decisions (SC-CAMLR- XXI, paragraph 5.15; SC-CAMLR-XXI, Annex 4, paragraph 5.15). Author(s):  Secretariat Title:

8. Options for allocating the precautionary catch limit of krill among small-scale management units in the Scotia Sea

   Abstract:  With the intent of stimulating discussion, we present four options for subdividing the precautionary catch limit of krill for Area 48 into the small-scale management units (SSMU) adopted at CCAMLR-XXI. The first three are static allocations: the first is proportional to estimated

9. Foraging strategies of chinstrap penguins at Signy Island, Antarctica: importance of benthic feeding on Antarctic krill

   Abstract:  Chinstrap penguins Pygoscelis antarctica are one of the major consumers of Antarctic krill Euphausia superba in the Southern Ocean. To examine their foraging strategy, we studied foraging trip patterns and diving behaviour of chinstrap penguins breeding at Signy Island, Antarctica, using

10. Distribution of foraging by female Antarctic fur seals

    Abstract:  The study examined the distribution of critical habitat for foraging by female Antarctic fur seals breeding at the island of South Georgia. Bathymetric features of the continental shelf around the island of South Georgia were an important indicator for the localisation of foraging. This
