Abstract: This paper updates the SIOFA Scientific Committee on Australia's bottom fishing impact assessment for the SIOFA area.

Recommendations … That WG-SAM note these preliminary explorations of alternative decision rules for managing toothfish fisheries, which indicate that an approach based on a harvest rate H: Would be consistent with the CCAMLR decision rule and its objective…

Recommendations … (1) That this research plan with a revised sampling design within six existing research blocks in Division 58.4.1 and one existing research block in Division 58.4.2 be adopted. (2) If directed fishing was not allowed in Division 58.4.1 in 2021/22…

In this paper, we report on fish bycatch during exploratory fishing activities undertaken in Divisions 58.4.1 and 58.4.2 during the period 2016 to 2022. Fish bycatch was composed of at least 14 species or species groups. In 2021 and 2022, exploratory fishing occurred in Division 58.4.2 only…

Elasmobranchs (sharks, skates and rays) are among the least productive fish species, which make their populations vulnerable to increased mortality. Although skates exhibit elevated vulnerability to fishing, they are commonly caught as incidental bycatch in demersal fisheries.

During April 2022, the annual random stratified trawl survey (RSTS) around Heard Island and McDonald Islands (HIMI) was conducted in CCAMLR Division 58.5.2, with the completion of 165 stations. The survey was conducted on the FV Cape Arkona.

The software platform CASAL (C++ algorithmic stock assessment laboratory) has been used to implement integrated statistical catch-at-age toothfish stock assessments in CCAMLR since 2005. However, CASAL is no longer being developed or maintained.

Exploratory fishing for Antarctic toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. Since 2017/18, exploratory fishing has been conducted under successive research plans by Australia, France, Japan, Republic of Korea and Spain. Here…

The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.

In response to a report of the incidental mortality of three juvenile humpback whales in the Antarctic … krill trawl fishery in Subareas 48.1 and 48.2 during the 2021 calendar year, SC-CAMLR reconvened … the Working Group on Incidental Mortality Associated with Fishing (WG-IMAF).

Physical features preserved in ice cores may provide unique records about past atmospheric variability. Linking the formation and preservation of these features and the atmospheric processes causing them is key to their interpretation as palaeoclimate proxies. We imaged ice cores from Law Dome…

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.

The zonal wavenumber spectrum of planetary waves in the atmosphere above Antarctica was studied in two contrasting years: in 2019 when there was a sudden stratospheric warming (SSW), and in 2020 when the Antarctic stratospheric vortex was unusually strong and long-lived.

We have considered TOMS (2000–2004) and OMI (2005–2021) total ozone column (TOC) data sets for the second part of winter cold period (January–March). Variations in both total ozone and characteristics of the Fourier wave harmonics with zonal numbers 1–5 are analyzed.

The Australian Antarctic Division (AAD)1 is undertaking planning activities for a proposal to construct and operate a new aerodrome near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project). The Davis Aerodrome Project would involve the construction of a 2.

To ensure effective restoration and environmental protection of fuel spill sites on Macquarie Island that have undergone remediation, the Australian Antarctic Division has developed site-specific Environmental Quality Guidelines and Remediation Targets.

From 27–29 March 2019, a technical workshop was held at the Australian Institute of Marine Science (AIMS) in Townsville, Queensland, Australia to discuss key issues associated with the derivation of water quality guideline values (GVs).

Australia has decided not to proceed with a proposal to construct and operate a paved runway near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project), following careful consideration of the likely environmental impact, cost and complexity of the project.

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)…

The Australian Antarctic Strategy and 20 Year Action Plan: Update 2022 reaffirms Australia's ongoing commitment to best practice environmental stewardship in Antarctica. Related high priority actions over the next five years include establishing a Cleaner Antarctica science program…

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…

Collaborative research has shown that diesel fuels used at Australian and Argentine Antarctic stations are chemically distinct. Such findings can assist with understanding the relative risks associated with fuel spills, the identification of specific compounds for monitoring…

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…
