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…
As we learn more about the importance of cetaceans in the Antarctic, including their populations' recovery and needs as krill and fish predators, it is increasingly clear that cetacean science is vital for informing ecosystem-based management.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
Atmospheric gravity waves play an important role in transporting energy and momentum between atmospheric spheres and drive circulations that affect key processes such as formation of the ozone hole and the cold summer polar mesosphere.
This Information Paper supplements Working Paper 43 by setting out draft criteria that might be applied to identified Important Bird Areas (IBAs) as well as to other bird colonies or aggregations1 when considering ASPA designation.
In 2015 the ATCM endorsed a report listing 204 Important Bird Areas (IBAs) across Antarctica and offshore islands south of 60o South. In doing so the ATCM adopted Resolution 5 (2015)…
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)…
Marine non-native species present an increasing threat to Antarctic marine ecosystems, particularly under climate change. This paper sets out progress with ongoing work initiated by the CEP Subsidiary Group on Climate Change Response (SGCCR)…
Increasing levels of chemical contamination in the Antarctica environment are resulting from global and regional human activities. Unlike other areas of the world, Antarctica lacks continent-wide systematic and coordinated monitoring of contaminants. Germany, Italy, Australia, United Kingdom…
There is growing evidence that the Antarctic is increasingly exposed to chemical stressors. Antarctica is impacted by global issues such as climate change and long-range transport of chemicals. Furthermore, expanding tourism and research activities…
This paper provides an update to the ATCM on the implementation of Resolution 8 (2021) Antarctica in Changing Climate, one year after its adoption.
As the ATCM was sadly cancelled in 2020, in light of the global Covid-19 pandemic, ATCMXLIII in 2021 is the first meeting of the Parties since the publication of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The SROCC…
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the ‘2018–19 Area 48 Survey’.
Supporting Antarctic scientific investigation is the job of the national Antarctic programmes, the government entities charged with delivering their countries’ Antarctic research strategies. This requires sustained investment in people, innovative technologies, Antarctic infrastructures…
Preliminary findings from the Australian contribution to the Chemistry-Climate Model Initiative (CCMI) are presented. This initiative builds on the 2nd Chemistry Climate Modelling Validation (CCMVal-2), Atmospheric Chemistry & Climate (AC&C) and other global modelling.
Results from the chemistry—atmosphere—climate model version of the Australian Community Climate and Earth System Simulator (ACCESS) are presented. ACCESS is based on the UK Met Office Unified Model version 7.3 (UM 7.3) including the United Kingdom Chemistry and Aerosols (UKCA) module.
