Coastal Antarctic ecosystems feature long periods of sea ice cover, strong seasonality in primary production, and low biodiversity relative to marginal ice zone regions. There are few records of annual cycles of biodiversity and abundance of neritic Antarctic zooplankton…
Incidental mortality in fisheries is a major driver of population declines for albatrosses and petrels globally. However, accurate identification of species can be difficult due to the poor condition of bycaught birds and/or visual similarities between closely related species.
Plankton, a diverse group of aquatic organisms, make Earth livable, regulate aquatic life, and provide benefits to human societies such as access to clean water, food security, and well-being. They also support economies and inspire biotechnological innovations.
A range of leaching protocols have been used to measure the soluble fraction of aerosol trace elements worldwide, and therefore these measurements may not be directly comparable.
The East Antarctic krill fisheries are spread across two Divisions of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), Division 58.4.1 between 80-150°E and Division 58.4.2 between 30-80°E.
Accidental fuel spills associated with the storage, transfer, and use of diesel fuel for power generation have occurred on sub-Antarctic Macquarie Island since the establishment of the island's research station in 1948.
Antarctic krill (Euphausia superba) aggregations are important in the Southern Ocean ecosystem; however, the amount of energy that krill swarms contain is unknown. We assessed the population structure of E.
Following a recommendation from the Advisory Committee, a Work Programme for the 2019 - 2021 triennium was adopted by the Sixth Session of the Meeting of the Parties (MoP6, Resolution 6.4).
At the Third Meeting of the Advisory Committee (AC3), 129 species of Procellariformes were assessed using a number of categories in order to provide Parties with an approximate priority list of species that might be considered for nomination to Annex 1 of ACAP (AC3 Doc 18).
WG-FSA-19 recommended an update on stock parameters, including recruitment indices from the trawl survey…
Abstract: This paper updates the SIOFA Scientific Committee on Australia's bottom fishing impact assessment for the SIOFA area.
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.
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)…
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…
Understanding the sensitivity of Antarctic organisms to metal exposure is essential … for developing Antarctic specific Environmental Guidelines to manage contamination risks. For … the first time…
The ozone loss simulated with climate models is based on laboratory kinetic data. These laboratory data are difficult to conduct at stratospheric pressures and temperatures and there is substantial uncertainty surrounding these parameters.
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
With the development of next generation aircraft designs capable of ultralong-range flight and … extended flight endurance…
Mitochondrial ribosomal DNA is commonly used in DNA-based dietary … analyses. In such studies, these sequences are generally assumed to be the … only version present in DNA of the organism of interest. However…
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
A series of nutrient-amended microcosms was used to investigate changing microbial communities during biodegradation in … hydrocarbon-contaminated Antarctic soils at 4, 10 and 42 °C. Although sample heterogeneity resulted in no statistically significant … reduction in total petroleum hydrocarbons…
Natural attenuation of petroleum hydrocarbons in polar and subpolar soils is limited by low nutrients, low temperatures, and … water availability.
Many contaminated cold region soils are deficient in nitrogen, and addition of the proper amount of this nutrient can increase the biodegradation rate. However…
Models of variability in Adélie penguin foraging trip durations were constructed and fitted … to data collected at Béchervaise Island over a 12-year period when only natural variation … was known to occur. Variability among trips and penguins was greater in the crèche … stage…
