  1. ABUNDANCE ESTIMATES FOR CRABEATER, WEDDELL AND LEOPARD SEALS AT THE ANTARCTIC PENINSULA AND IN THE WESTERN WEDDELL SEA (90º - 30º W, 60º - 80º S)

    Abstract:  This paper presents spatial modelling based abundance and density estimates of pack-ice seals, crabeater, Weddell and leopard seals, based on aerial survey line transect data collected in January 1999 under the Antarctic Pack-Ice Seal (APIS) programme. Estimates are reported for the

    Meeting Document : WG-EMM-PSW-08/06 : Author(s): J. Forcada and P.N. Trathan (United Kingdom)

  2. SPATIAL AND TEMPORAL VARIATION IN ATTRIBUTES OF ADELIE PENGUIN BREEDING POPULATIONS: IMPLICATIONS FOR UNCERTAINTY IN ESTIMATION OF THE ABUNDANCE OF BREEDING PENGUINS FROM ONE-OFF COUNTS

    Abstract:  Broad-scale surveys of penguin breeding abundance generally rely on on-off counts of adults, nests or chicks across several or many breeding sites, and the timing of these counts is often outside the control of researchers. Time series counts of Adelie penguin breeding population

    Meeting Document : WG-EMM-PSW-08/07 : Author(s): C. Southwell, J. McKinlay, R. Pike, D. Wilson, K. Newbery and L. Emmerson (Australia)

  3. ASPECTS OF POPULATION STRUCTURE, DYNAMICS, AND DEMOGRAPHY OF RELEVANCE TO ABUNDANCE ESTIMATION: ADÉLIE PENGUINS

    Abstract:  Counts of Adélie penguin populations are most conveniently and most often undertaken at breeding sites during the breeding season. The objective of this paper is to identify and describe the aspects of Adélie penguin population structure, dynamics and demography that are relevant to the

    Meeting Document : WG-EMM-PSW-08/09 : Author(s): L. Emmerson and C. Southwell (Australia)

  4. SEASONAL ESTIMATION OF ABUNDANCE BY BOOTSTRAPPING INEXACT RESEARCH DATA (SEABIRD): A METHOD FOR ASSESSING ABUNDANCE AND UNCERTAINTY FROM HISTORICAL COUNT DATA USING ADELIE PENGUINS AS A CASE STUDY

    Abstract:  In addition to a review of published studies on Adelie penguin abundance at breeding sites in Antarctica, Southwell (2004) proposed a general abundance estimator appropriate for a species of that kind. The present study attempts to implement this estimator in the form of a parametric

  5. A BRIEF SUMMARY OF ADELIE PENGUIN COUNT DATA FROM EAST ANTARCTICA

    Abstract:  This paper very briefly summarises some aspects Adelie penguin count data from east Antarctica to demonstrate the extent and nature of variability in data from this large region, and to provide some background to some aspects of the R program SEABIRD outlined in McKinlay and Southwell

  6. Report of review group of data sources on odontocetes in the Southern Ocean in preparation for IWC/CCAMLR workshop in August 2008

    Author(s):  Van Waerebeek, K., Best, P.B., Donovan, G.P., Branch, T.A., Murase, H., Leaper, R. Title:  Report of review group of data sources on odontocetes in the Southern Ocean in preparation for IWC/CCAMLR workshop in August 2008 Approval:  Approved

  7. A REVIEW OF BIAS AND UNCERTAINTY IN ANTARCTIC PACK-ICE SEAL ABUNDANCE ESTIMATES

    Abstract:  While the joint CCAMLR-IWC workshop will consider a number of parameters for species groups, including abundance, trends in abundance, habitat utilisation, foraging and growth, this review of pack-ice seals focuses primarily on abundance and to a lesser extent trends in abundance. The

  8. Report of the review group on sources of data on Antarctic fur seals Arctocephalus gazella in the Southern Ocean in preparation for the CCAMLR-IWC workshop, August 2008

    Author(s):  Daneri, G., Kovacs, K., Hofmeyr, G., Torres, D., Gales, N., Martin, T., Staniland, I., Goebel, M., Osman, L., Vallejos, V., Blank, O., Reid, K., Guinet, C., Forcada, J.

  9. Krill population trends

    Abstract:  Krill (Euphausia superba) distribution and abundance data are available from a number of sources: from net surveys (the longest historical series of available date), from acoustic surveys, from fisheries data and from the distribution of krill predators. Each of these forms of data

  10. CCAMLR-IWC Export Group Report: Primary Productivity and Phytopalnkton

    Abstract:  This report summarizes the satellite ocean color (chlorophyll) data that are currently available, from missions beginning with the Coastal Zone Color Scanner in the late 1970s through to the SeaWiFS and MODIS sensors that have been providing data for the last ten years. The
