Ten years of recent fine-scale haul-by-haul krill data were used to characterise the … behaviour of the krill fishery. Analysis of distance between hauls in relation to their catch … level revealed a distinct pattern.

This article summarises the history of the discovery of emperor penguin Aptenodytes forsteri colonies. Emperor penguins were probably first seen on James Cook’s second voyage (1773–1775) but were not recorded as a … separate species until 1844.

Flexibility in foraging behaviour and diet are characteristics of many penguin species. While these 2 aspects of foraging ecology are presumably tightly coupled, the connection between … them is rarely examined directly.

1. Incidental mortality in fisheries is causing declines in many albatross populations around the world. To assess potential interactions with regional fisheries satellite tags were used to track black-browed albatrosses (Thalassarche melanophrys) and light-mantled sooty albatrosses…

We developed a computer program (HeardMap) to receive, manage, visualise and analyse Argos location data and … synchronised archival dive data.

The diet of free-living pinnipeds is most frequently estimated through identification of otoliths, squid mouth-parts and exoskeletons … of prey in scats. This is because, although important prey types may not always be detected, sample collection is non-invasive and … analysis is easy.

The Ade´lie penguin is broadly distributed throughout the … Antarctic, with a minimum breeding population of c. 2.5 … million pairs (Woehler 1993). This value is based on many … separate, independent studies at smaller scales…

Potential Ad´elie penguin Pygoscelis adeliae breeding habitat in the AustralianAntarctic Territory (AAT: 45◦E–136◦E, 142◦E–160◦E) was mapped using a geographic information system (GIS)…

Euphausiids are vital components of many oceanic foodwebs. Due to their large size, they are key prey … species for many vertebrates, and several species are subject to commercial fisheries. The best studied … euphausiid species is Antarctic krill (Euphausia superba)…

Seabird surveys in January – March 2006 of a poorly known area of the Southern Ocean … adjacent to the East Antarctic coast identified six seabird communities, several of which were … comparable to seabird communities identified both in adjacent sectors of the Antarctic…

A large-scale interdisciplinary survey of the waters between 30-80°E will take place between … January and March 2006.

We attached satellite tags to 16 humpback whales off South Eastern Australia in October/November 2008. The tags transmitted for an average of 55 days (range: 3-156 days) and provided data on migratory movements between Australia and the Antarctic feeding grounds.

This short paper describes 3 consistent regional differences in fin whale vocalizations recorded in the Southern … Ocean. Long term recordings were analysed from locations in eastern and western Australia, and locations south of … these in the Antarctic.

The diversity of parasites found on Nyctiphanes simplex and Nematoscelis difficilis … (Order Euphausiacea) was compared during 10 oceanographic cruises made off both coasts of the … Baja California peninsula, Mexico. We tested the hypothesis that N.

We examine global phylogeography of the two forms of giant petrel Macronectes spp. Although previously … considered to be a single taxon, and despite debate over the status of some populations and the … existence of minimal genetic data (one mitochondrial cytochrome b sequence per form)…
