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.
The Antarctic coastal marine region is a unique and highly complex environment, of which landfast ice and polynyas are key features, especially in the context of dense water formation. Current large-scale ocean-sea ice models used in climate studies simulate hardly any Antarctic landfast ice…
The Southern Ocean surrounding Antarctica harbours some of the most pristine marine environments remaining, but is increasingly vulnerable to anthropogenic pressures, climate change, and invasion by non-native species.
The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021)…
Like many polar animals, emperor penguin populations are challenging to monitor because of the species' life history and remoteness. Consequently, it has been difficult to establish its global status, a subject important to resolve as polar environments change.
Mapping Antarctic Specially Protected Areas (ASPAs) remains a critical yet challenging task, especially in extreme environments like Antarctica. Traditional methods are often cumbersome, expensive, and risky, with limited satellite data further hindering accuracy.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of -9.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. In Part I, we assessed the meteorological drivers that generated an intense atmospheric river (AR)…
To understand the scope and scale of the loss of biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land to the open ocean.

Report submitted to CCAMLR: Leaper, R., Biuw, M., Favero, M, Forster, I., Johnson, C., Kelly, N., Heinemann, D., Hines, E., Landry, S., Mattila, D., Meyer, M., Parker, S., Passadore, C., Reeves, S., Soffker, M., Stimmelmayr, R., Walker, N., 2022.
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.
Fisheries are human activities that alter resource availability for species in marine ecosystems. While fisheries remove fish biomass, they may also provide new feeding opportunities to various marine predators. These species, depredating on catches directly on the fishing gear…
Exploratory fishing for toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. Robust stock assessments and catch limits according to CCAMLR decision rules remain to be determined for these Divisions.
Spanish and Australian scientists are working on the age and growth estimates of Antarctic toothfish within divisions 58.4.1 and 58.4.2 from 2015 and 2017 respectively. During 2019, Korean scientists have joined this colaborative work.
Publication: 2019. Final Report, FRDC Project 2017/021. Australian Antarctic Division and the Fisheries Research and Development Corporation. Kingston, Australia. ISBN 978-1-876934-33-0. For this study, Antarctic toothfish samples were collected from CCAMLR Subareas 48.2, 48.4, 48.6, 88.1, 88.
This paper presents an updated assessment for the Patagonian toothfish (Dissostichus eleginoides) fishery at Heard Island and McDonald Islands (HIMI) in CCAMLR Division 58.5.2 with catch until the end of 2019 and observations until the end of 2018.
During late March to early April 2019, 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 150 stations. The survey was conducted on the FV Atlas Cove.
A draft workplan to develop a Management Strategy Evaluation for the CCAMLR Trend Analysis Rules and alternative data-limited approaches for managing toothfish fisheries under research plans is presented for discussion by WG-FSA.
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.
