Horizontal and vertical distribution and demography of euphausiids in the Ross Sea and its adjacent waters in 2004/2005
Abstract: The horizontal and vertical distribution and population structure of euphausiids in the Ross Sea and its adjacent waters were investigated during the summers of 2004/2005 using stratified towed samples. Nine species of euphausiids occurred in the survey area. Among them, Euphausia

THE POWER OF ECOSYSTEM MONITORING
Abstract: 1. Implementing an ecosystem approach to fisheries management requires an effective ecosystem monitoring programme, the utility of which depends upon its ability (measured by the statistical power) to detect effects that trigger management action. 2. Using data from a long-term ecosystem

INTERANNUAL SPATIAL VARIABILITY OF KRILL (EUPHAUSIA SUPERBA) INFLUENCES SEABIRD FORAGING BEHAVIOR NEAR ELEPHANT ISLAND, ANTARCTICA
Abstract: We investigate the influence of krill (principally Euphausia superba) patchiness on the foraging distributions of seabirds to understand how variation in krill influences patch dynamics between krill and birds. At sea surveys were conducted near Elephant Island, Antarctica for three

THE WHITE-CHINNED PETREL (PROCELLARIA AEQUINOCTIALIS) ON SOUTH GEORGIA: POPULATION SIZE, DISTRIBUTION AND GLOBAL SIGNIFICANCE
Abstract: More white-chinned petrels (Procellaria aequinoctialis) are accidentally killed in fisheries than probably any other seabird in the world, but the population impact of this mortality is poorly understood, partly because there have been no estimates of the species’ abundance in recent

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
