  1. Krill biomass estimates for two survey boxes to the north east and north-west of South Georgia in January 1996: the beginning of a five-year monitoring program

    Abstract:  Acoustic surveys were carried out in January 1996 within two 100 x 80 km boxes located over the shelf-break to the north-east and north-west of South Georgia. Surveys were conducted from RRS James Clark Ross using a Simrad EK500 echo-sounder operating at 38, 120 and 200 kHz. These

  2. A synoptic review of energetic requirements of southern ocean krill predators

    Abstract:  The purpose of this paper is to synthesize information on the energetics and food requirements of krill predators that may be in the most direct competition with the krill fishery. These krill predators are the Adélie (Pygoscelis adeliae), chinstrap (Pygoscelis antarctica), gentoo

  3. A model at the level of the foraging trip for the indirect effects of krill (Euphausia superba) fisheries on krill predators

    Abstract:  1. Although the development of fisheries for krill in the southern oceans has prompted considerable work on the indirect effects of fisheries on krill predators, to date all work has focused on population level effects. Here, we present for. the first time a model at the level of the

  4. Climate change and zooplankton dominance in the Antarctic marine ecosystem: implications for the food web

    Abstract:  There is a growing body of evidence that the climate of the Antarctic Peninsula region has been warming over the past 40 years with an associated decreased frequency of winters with extensive sea-ice development. These trends potentially will have a major impact on the structure and

    Meeting Document : WG-EMM-96/21 : Author(s): Siegel, V., Fraser, W., Trivelpiece, S., Holm-Hansen, O., Loeb, V., Hewitt, R., Trivelpiece, W.

  5. Indices of prey availability near the Seal Island CEMP site: 1990 through 1996

    Abstract:  Four indices of prey availability are calculated for prey surveys conducted in the vicinity of the Seal Island CEMP site during the austral summers of 1990-96. The indices are measures of average prey density, depth, distance from Seal Island, and persistence over time. Acoustic data

  6. Distribution, biomass and abundance of Antarctic krill in the vicinity of Elephant Island during the 1996 austral summer

    Abstract:  Results from two acoustic and net surveys conducted in the vicinity of Elephant Island during the 1996 austral summer indicate very good krill recruitment from spawning in 1994/5. Areas of high krill density were mapped north of King George and Elephant Islands where water depth was

  7. Areal and seasonal extent of sea-ice cover off the northwestern side of the Antarctic Peninsula: 1979 through 1995

    Abstract:  Analysis of seasonal sea ice cover of a 1,250,000 km2 area off the northwestern side of the Antarctic Peninsula indicates that four "ice events" have occurred during the last 1 7 years. The most recent event was first apparent in 1994 and continues through the latest data

  8. Reporting of fine-scale krill data in the 1994/95 season

    Author(s):  Secretariat Title:  Reporting of fine-scale krill data in the 1994/95 season Approval:  Approved

    Meeting Document : WG-EMM-96/26 : Author(s): Submitted by Ukraine

  10. A way forward in the multivariate analysis of Antarctic predator, prey and environment indices: predator-environment interactions at Seal Island

    Abstract:  The CCAMLR Ecosystem Monitoring Programme has two aims: to detect changes in critical components of the antarctic ecosystem, and to distinguish between changes due to the harvesting of commercial species and changes due to environmental variability. Data from Seal Island are used to
