1. Monitoring a marine ecosystem using responses of upper trophic level predators

   Abstract:  1. This study examined the changing status of the marine ecosystem at the island of South Georgia (Southern Ocean) using up to 27 variables measured over 22 years from 3 upper trophic level predators that specialise in foraging upon krill (Eupuasia superba Dana). These variables included

2. Spatial distribution of foraging by female Antarctic fur seals

   Abstract:  The study tested the hypothesis that the distribution of critical habitat for foraging by female Antarctic fur seals breeding at the island of South Georgia was influenced by physical gradients in the oceans and also by the need to avoid local competition for food. It also tested the

3. Integrated environment–prey–predator interactions off South Georgia: implications for management of fisheries

   Abstract:  The oceanography of the South Georgia region is principally that of the Southern Ocean rather than the South Atlantic. A combination of factors, including advection, local bathymetry and high local productivity, leads to relatively large concentrations of krill (Euphausia superba) in the

4. Variability of krill biomass estimates in repeated mesoscale surveys in relation to CCAMLR-2000 Survey

   Abstract:  One of the important problems in interpreting CCAMLR-2000 results is how they reflect the krill biomass status, is it high, medium or low at the present time. The comparative analysis of krill biomasses derived from trawl catches was carried out; retrospective data of three Soviet

5. Alternative methods for determining subarea or local area catch limits for krill in Statistical Area 48

   Abstract:  CCAMLR Conservation Measure 32/X sets a 1.5 million metric ton precautionary catch limit on krill (Euphausia superba) in Statistical Area 48. The measure also implies the application in future of precautionary limits could be applied to subareas or local areas. Nine alternative methods

6. Distribution of temperature, salinity, density and flow across the Drake Passage in December 1994

   Abstract:  This paper presents vertical distribution of temperature, salinity, density and flow across the Drake Passage. The seventh Antarctic Ocean Survey cruise by the R/V Kaiyo Maru of the Japanese Fisheries Agency was conducted in the waters around the Antarctic Peninsula in 199/95 austral

7. Sources of information on Global Marine Protected Areas (MPAs)

   Abstract:  This information paper is a compilation of websites and publications on Marine Protected Areas (MPAs). The paper is intended as an educational guide and contains an array of national, international, academic, governmental, and non-governmental sources. The list is not exhaustive and

8. Penguin demography and winter distributions in the Antarctic Peninsula region

   Abstract:  Our long-term seabird research at Admiralty Bay has documented annual variability in the life history parameters of the breeding biology and ecology of Adélie, gentoo, and chinstrap penguins. Long-term data acquired on these species including: survival and recruitment, population size

9. Seabird research on Cape Shirreff, Livingston Island, Antarctica, 2000/01

   Abstract:  The austral summer 2000/01 marked the fourth full season of land-based predator research at Cape Shirreff, Livingston Island, Antarctica. Results of the monitoring activities undertaken in support of CCAMLR WG-EMM, are summarized in the report Author(s):  M. Taft, I. Saxer and W.

10. Interannual variability of polynya extent in the Antarctic Ocean

    Abstract:  There are two general kinds of polynya (an ice-free area within sea ice borders), coastal polynya and open ocean polynya, in the Southern Ocean. Polynya accelerates oceanic and atmospheric processes by exposing the surface of ocean to the atmosphere. Additionally, we think that the
