Surveillance monitoring is important for detecting variations in species populations in response to natural and anthropogenic environmental changes. For seabirds this typically involves species-specific monitoring at breeding colonies.
Incidental mortality in fisheries is a major driver of population declines for albatrosses and petrels globally. However, accurate identification of species can be difficult due to the poor condition of bycaught birds and/or visual similarities between closely related species.
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.
The largest regional drivers of current surface elevation increases in the Antarctic Ice Sheet are associated with ice flow reconfiguration in previously active ice streams, highlighting the important role of ice dynamics in mass balance calculations. Here…
Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach…
The Antarctic environment is extremely cold, windy and dry. Ozone depletion has resulted in increasing ultraviolet-B radiation, and increasing greenhouse gases and decreasing stratospheric ozone have altered Antarctica's climate.
The 7th International Zooplankton Production Symposium was held in Hobart, Australia in March, 2024 with the theme 'New Horizons', chosen to reflect the current perception that oceans are now experiencing greater human impacts than ever before, and to explore how zooplankton are impacted.
New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world's experts on sea ice … Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice…

Vincennes Bay is a region of East Antarctica vulnerable to sub-ice shelf basal melting from warm ocean water intrusions. The sub-ice shelf bathymetry in this region is largely unknown, despite its importance for ocean dynamics within ice shelf cavities and associated sub-ice shelf basal melting.
Aim … To map presence, absence and ignorance of Antarctic seabird breeding occupancy at the spatial resolution of ice-free habitat sites to identify knowledge gaps and inform management and conservation. Location … East Antarctica between longitudes 30°?E and 150°?E.
Mosses play a key role in Antarctic ecosystems. Understanding of moss diversity and its likely drivers across Antarctica is, however, limited, as is the extent to which Antarctic Specially Protected Areas (ASPAs) represent this diversity.
Genomic adaptation and introgression can occur during the speciation process, enabling species to diverge in their frequencies of adaptive alleles or acquire new alleles that may promote adaptation to environmental changes.
The distribution of New Zealand sea lions is typically localised to New Zealand and its remote subantarctic islands. However, non-resident male sea lions were seen on Macquarie Island, 650 km from their nearest natal islands, in all months of all years from 1965 to 1980.
Conserving landscapes used by multiple stakeholder groups requires understanding of what each stakeholder values. Here we employed a semi-structured, participatory approach to identify features of value in the terrestrial Antarctic Peninsula related to biodiversity, science and tourism.
Heard Island and McDonald Islands (HIMI) are an external Territory of Australia, located approximately 4000 kilometres southwest of Australia in the southern Indian Ocean.
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds…
This Report documents discussions and recommendations of the Tenth Meeting of the Seabird Bycatch Working Group (SBWG10), held online, from 17 - 19 August (AEST/UTC+10).
This report to the Seventh Meeting of the Parties has been prepared by the Advisory Committee Chair and Vice-chair with the assistance of the Agreement's Secretariat under Article IX 6 (e).
This report to the Seventh Meeting of the Parties has been drafted as a document in progress for the Advisory Committee by the Chair and Vice-chair with the assistance of the Agreement's Secretariat.
Minimising seabird interactions with longline operations is a key objective of the management of fisheries in CCAMLR (see e.g. Conservation Measure CM 25-02 and 41-08). Longline fishing in the fishery for Patagonian toothfish (Dissostichus eleginoides) in Statistical Division 58.5.
