The zonal asymmetry in the Antarctic total ozone column (TOC) has been widely studied in … recent decades. However, little is known about how spatially dependent the TOC response is to sudden … stratospheric warmings (SSWs).
Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…
Sea-ice surface temperature from atmospheric reanalysis has been used as an indicator of ice melt and climate change. However, its performance in atmospheric reanalyses is not fully understood in Antarctica. Here, we quantified biases in six widely-used reanalyses using satellite observations…
Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…
During the summer of 2021, we conducted a comprehensive study on zooplankton communities along East Antarctica (55°E to 80°E) as part of the Trends in Euphausiids off Mawson, Predators, and Oceanography (TEMPO) survey program.
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
Genetic diversity is fundamental to biological diversity, vital for species’ health and adaptation to environmental change. Under the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF)…
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.

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…
Due to its persistence and potential ecological and health impacts, mercury (Hg) is a global pollutant of major concern that may reach high concentrations even in remote polar oceans. In contrast to the Arctic Ocean…
Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity are affected by different environmental factors including anthropogenically forced ocean and climate change. Until now…
Persistent organic pollutants (POPs) are well known to accumulate in polar food webs; yet there is little ecotoxicological data available for environmental risk assessment of POPs in these extreme ecosystems. The premise of the tissue residue approach (TRA)…
Current interpretation of histological alteration in fish as an indicator of contaminant impact is subjective. Generally severity of alteration is poorly described, and does not allow direct comparison between studies. A histological health index (HHI) modified from Bernet et al (1999)…
Polar communities are expected to experience the impacts of ocean acidification sooner and more heavily than other regions, and serve as indicators of the consequences we can expect from increasing ocean CO2 concentrations.
Terrestrial fuel spills in Antarctica commonly occur on ice-free land around research stations as the result of human activities. Successful clean-up of spills not only requires appropriate remediation strategies and technologies that are effective in cold climates…
Several fuel spills have occurred near Australia’s Antarctic stations, associated with the use of SAB diesel for power generation. This has resulted in significant petroleum hydrocarbon contamination in soils.
