Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved through acoustic-trawl surveys.

We investigated Weddell seal (Leptonychotes weddellii) and leopard seal (Hydrurga leptonyx) vocalizations using passive acoustic monitoring beneath landfast ice and open water, 5.6?km seaward from Davis Station, East Antarctica. Eight-minute recordings were manually sampled at 1?h intervals over 24?

Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high post-larval krill recruitment the following spring, suggesting that sea ice plays a critical role in larval overwinter survival.

Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging…

Poor coverage of the Antarctic continental shelf bathymetry impedes understanding the oceanographic processes affecting Antarctica’s role in global climate. Continental shelf bathymetry influences warm modified Circumpolar Deep Water movement onto the shelf…

Both net sea ice extent (SIE) and area (SIA) were close to the 1981–2010 average for January through August 2016, after which there was a dramatic departure from the mean through to the end of the year (Fig. 6.8a). Maximum net SIE peaked on 31 August (18.44 × 106 km2)…

Antarctic krill are a fundamental component of Southern Ocean ecosystems and perturbations to krill populations have ramifications for the entire ecosystem. Krill are fished across the Southern Ocean and sustainable management of this fishery is a high priority for the Australian Government.

INTRODUCTION The Commission and the Scientific and Conservation Committees have adopted numerous recommendations over the years for strengthening engagement with other organisations. The IWC Secretariat, in collaboration with members of the SC and CC have been working to carry out these mandates…

This paper summarises the outcomes of a quantitative analysis of the extent of Antarctic wilderness, recently published in Nature (Leihy et al., 2020). The researchers assembled an extensive database of ground-based human activity across the Antarctic continent and offshore islands…

This paper draws attention to the publication in the scientific journal Nature of the results of the Retrospective Analysis of Antarctic Tracking Data (RAATD), a project of the Scientific Committee on Antarctic Research (SCAR)…

Antarctic krill (Euphausia superba) is a keystone species of the Southern Ocean, vastly abundant and an essential food source of some of the Southern Ocean's most charismatic predators, including penguins, seals, and baleen whales. Antarctic krill are also targeted by a krill fishery…

Antarctic krill (Euphausia superba) is a keystone species in the Southern Ocean ecosystem, and monitoring its distribution and abundance is crucial for the sustainable management of expanding fisheries targeting the species. Environmental DNA (eDNA)…

Introduction: v … 1. The annual meeting of the SCAR Krill Action Group (SKAG) was held online from 7 to 11 March 2022 at 1500-1700 UTC, with a series of Zoom meetings. 2.

The relationships between flying Antarctic seabirds and their at-sea environments remain poorly understood, particularly outside of the breeding season. Improving our knowledge of how these marine predators use their habitat is a critical step towards conservation of these species.

The contamination of the marine environment surrounding coastal Antarctic research stations remains insufficiently understood in terms of its extent, persistence, and characteristics. We investigated the presence of contaminants in marine sediments near Casey Station…
