Measurements of sound-speed and density contrasts of Antarctic krill (Euphausia superba) on board RV Kaiyo Maru
Abstract: In order to calculate the target strength of Antarctic krill (Euphausia superba) using an acoustical scattering model, information on size, morphology, orientation, sound–speed and mass-density contrasts between the animal and the surrounding water are required. Sound-speed and mass

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

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

ESTIMATING THE NUMBER OF PRE- AND INTERMITTENT BREEDERS ASSOCIATED WITH THE BÉCHERVAISE ISLAND ADÉLIE PENGUIN POPULATION
Abstract: The size of two of the inaccessible (non-breeding) components of the Adélie penguin population associated with the Béchervaise Island breeding population is estimated over the past decade using a series of mark-recapture analyses and some simple population modelling techniques. Author(s)

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

FLYING SEABIRDS IN AREA 48; A REVIEW OF POPULATION ESTIMATES, COVERAGE AND POTENTIAL GAPS IN SURVEY EXTENT AND METHODS
Abstract: Published accounts of population surveys and population estimates for flying seabirds across Area 48 are reviewed. Spatial coverage of count data and population estimates varies greatly between species across their breeding ranges in Area 48. Most population estimates reviewed date from

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
