  1. Status and trends of Adelie penguin populations in the Ross Sea region

    Abstract:  Aerial reconnaissance and photography were used in the Ross Sea sector of Antarctica to determine the breeding locations of Adé1ie penguins Pygoscelis adeliae, and to count the numbers of nests occupied during the early incubation period. From 1981 to 1987, all islands and sea coasts

    Meeting Document : WG-CEMP-92/23 : Автор(ы): R.H. Taylor, P.R. Wilson and B.W. Thomas (New Zealand)

  2. New Zealand Antarctic research programme

    Abstract:  Since parameters of penguin populations may provide good indices of the abundance of the key prey species (krill) and thus the state of the Antarctic marine ecosystem, aerial reconnaissance and photography are used in the Ross Sea sector of Antarctica to determine where Adelie penguins

  3. Preliminary assessment of the data available for estimating the krill requirements of crabeater seals

    Author(s):  J.L. Bengtson (USA), T.J. Härkonen (Sweden) and P. Boveng (USA) Title:  Preliminary assessment of the data available for estimating the krill requirements of crabeater seals Approval:  Approved

  4. Krill biomass and distribution variability in Subarea 48.3 in June 1991

    Abstract:  Temporal and spatial variability of krill distribution features was investigated at the micropolygon of 8 x 6 miles, where eight consecutive hydroacoustic stations were carried out. Krill aggregations occurred as fields of small swarms of spatial distribution features (size and density

  5. Report of biological observations carried out on board the krill fishing vessel More Sodruzhestva in April to August 1991

    Abstract:  An observation program was carried out by a biologist-observer on board the krill fishing vessel More Sodruzhestva in April to August 1991 in Subareas 48.2 and 48.3. The program included observation of krill fishing operations, collection and processing of catch samples for analysing

  6. Status of krill target strength

    Abstract:  Empirical estimates for the target strength of krill are extracted from the literature. These are confined to measurements on aggregations of live euphausiids, which should avoid a frequent cause of bias in single-animal measurements, namely thresholding. Theoretical estimates for the

  7. Variability of krill stock composition and distribution in the vicinity of Elephant Island during AMLR investigations 1988-1992

    Abstract:  Krill stock composition and distributional patterns in the vicinity of Elephant Island during austral summer 1988-1992 are described. Changes in both size and maturity composition over the five year period indicates strong recruitment from the 1987/88 and 1990/91 year classes and poor

  8. 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 asks the Scientific Committee to provide the Commission with advice on how precautionary limits could be applied to subareas or

  9. Calibration of an acoustic echo-integration system in a deep tank, with system gain comparisons over standard sphere material, water temperature and time

    Abstract:  This paper outlines the theory and procedures for calibrating an echo integration acoustic system with a standard sphere. It presents the results of an extensive calibration of a Simrad EK500 scientific echo sounder with a 120 kHz sprit-beam transducer in a refrigerated 10m deep tank.

  10. Krill catch distribution in relation to predator colonies, 1987-1991

    Abstract:  The distribution of krill catches in relation to predator colonies in Subareas 48.1 and 48.2 is shown. 74-90% of catches in Subarea 48.1 are taken within 100 km of predator colonies between December and March, and these are between 10 and 18% of the estimated total penguin consumption in
