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.
Dimethyl sulfide (DMS) and methanethiol (MeSH) are biologically co-produced marine volatile sulfur compounds, which play a critical role in climate-cooling aerosol formation. The spatio-temporal distributions of MeSH are poorly constrained, especially over the Southern Ocean.
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)…
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.
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.
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…
Concentrations of UV-B absorbing pigments and anthocyanins were measured in three moss species, over a summer growing season in Antarctica. Pigment concentrations were compared with a range of climatic variables to determine if there was evidence that pigments were induced by UV-B radiation…
Concentrations of UV-B absorbing pigments and anthocyanins were measured in three moss species, over a summer growing season in Antarctica. Significant seasonal differences were found in the potential UV-B screening pigments. The most exposed species, Ceratodon purpureus…
Antarctica has been exposed to increases in ultraviolet-B (UV-B) radiation as a result of … ozone depletion for several decades. In addition, climate change will alter temperature and … water availability to plant communities over the next century. Recent studies…
Concentrations of UVB (ultraviolet B) absorbing pigments and anthocyanins were … measured in three moss species, over a summer growing season in Antarctica.
Seasonal changes in the photosynthetic and photoprotective pigment content of three species of Antarctic moss; Grimmia antarctici…
