1. Population, breeding, diet and conservation of Crozet shag Phalacrocorax [atriceps] melanogenis at Marion Island, 1994/95 to 2002/03

   Abstract:  The number of Crozet shags or cormorants Phalacrocorax [atriceps] melanogenis breeding at subantarctic Marion Island decreased by 68% from 841 pairs in 1994/95 to 272 pairs in 2002/03. The mean number of pairs at colonies also decreased and was significantly related to the overall number

2. Population numbers of fur seals at Prince Edward Island, Southern Ocean

   Abstract:  During the period 17–22 December 2001, the onshore distribution and the abundance of Antarctic fur seals Arctocephalus gazella and Subantarctic fur seals A. tropicalis were determined for Prince Edward Island (46°38´S, 37°57´E). Two breeding colonies of Antarctic fur seals were located

3. Absence of haematozoa in breeding macaroni Eudyptes chrysolophus and rockhopper E. chrysocome penguins at Marion Island

   Abstract:  Haematozoan infections cause the death of penguins in captivity, but seldom in the wild. No haematozoa were found in 89 blood smears taken from macaroni penguins Eudyptes chrysolophus or 80 smears from eastern rock-hopper penguins E. chrysocome filholi at subantarctic Marion Island

4. Modern mean monthly SST and SST anomalies off South Georgia during recent years (based on satellite data)

   Abstract:  VNIRO has carried out monitoring of sea-surface temperatures (SSTs) in Subarea 48.3 (South Georgia). Current satellite surveys provide constant information for modern appreciation of changing the mean monthly SST and SST anomalies during recent years. Daily satellite data from GOES-E and

6. Preliminary analyses in support of the CEMP Review Workshop: power analyses

   Abstract:  A series of power (sensitivity) analyses of CEMP indices was made using the DOS-based software MONITOR (J. P. Gibbs, 1995). In all, 170 time series were investigated for their power to detect change over the range –10% to +10% of a mean survey value. Each run of MONITOR involved the

7. Preliminary analyses in support of the CEMP Review Workshop: serial correlations

   Abstract:  As part of the preliminary analyses undertaken in preparation for the CEMP Review Workshop, the Secretariat has documented serial correlation in time series of CEMP indices. The values input to the serial correlation analysis were the ‘transformed’ annual index values reported in WG-EMM

8. Different CPUE types in Soviet krill fishery statistics in 1977–1992

   Abstract:  The various CPUE indices used in Soviet krill fishery statistics and their main sources and primary data for their calculations were considered. The main CPUE indices were catch per fishing day (CFD), catch per extended fishing day (CEFD) and catch per hour (CH). The primary data for all

9. Ecosystem indicators: factors affecting the choice of predator performance indices for use in monitoring programmes

   Abstract:  The ability to use upper-trophic level species as ecosystem indicators is determined by the ability to relate changes in indices of their performance to changes at lower trophic levels. Using indices of predator performance from four species of krill-eating predator together with

10. Trends in bird and seal populations as indicators of a system shift in the Southern Ocean

    Abstract:  Although world oceans have been warming over the past 50 years, the impact on biotic components is poorly understood because of the difficulty of obtaining long-term data sets on marine organisms. The Southern Ocean plays a critical role on global climate and there is growing evidence of
