Identification of species' Biologically Important Areas (BIAs) is fundamental to conservation planning and species distribution models (SDMs) are a powerful tool commonly used to do this.
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.
In this paper, we report on fish by-catch during exploratory fishing activities undertaken in Divisions 58.4.1 and 58.4.2 during the period 2014 to 2020. Fish by-catch comprised 12 species or groups of species. In 2019 and 2020, exploratory fishing occurred exclusively in research block 58.4.
We present an update of ageing and estimates of biological parameters, and of the single-region integrated stock assessment for Antarctic toothfish (Dissostichus mawsoni) fishery in CCAMLR Divisions 58.4.1 and 58.4.2. The update of ageing and estimates of biological parameters addresses Milestone 1.
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…
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…
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…
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean…
Length frequency data (LFD) are an important input to integrated stock assessments, and statistical tests for variables that significantly influence the length distribution of fish can assist in the definition of effort strata, typically denoted as fisheries or sub-fisheries…
This study presents the first analysis of the energetics … associated with a hybrid cyclone’s transition in the Southern … Hemisphere, Hurricane Catarina (March 2004). Catarina has … earned a place in history as the first documented South … Atlantic hurricane…
Transition mechanisms characterizing changes fromhurricanes tomidlatitude cyclones … and vice-versa (extratropical and tropical transition) have become a topic of increasing … interest…
DNA-based techniques have proven useful for defining trophic links in a variety of … ecosystems and recently developed sequencing technologies provide new opportunities … for dietary studies. We investigated the diet of Australian fur seals (Arctocephalus pusillus … doriferus)…
Satellite remote sensing observations of three break-up events in 2008 for the Wilkins Ice Shelf (28 February … to 6 March, 27 May to 31 May, and 28 June to mid-July) provide unprecedented detail of ice shelf calving … during rapid break-up.
Identification of DNA sequence diversity is a powerful means for assessing the … species present in environmental samples.
Seismic anisotropy is investigated across the previously unstudied region of central East Antarctica including new coastal locations and remote, temporary stations far inland.
The preservation of tardigrade eggs and exuviae in Antarctic lake sediments provided an opportunity to assess post-glacial … colonisation and Holocene tardigrade dynamics on the southern continent. Tardigrade eggs were recovered from five lakes…
Long-range forecasts of Antarctic sea ice are tery much in demand, not only because of … the potential importance of sea ice in global climate, but also for the practical purpose of … exploring the Antarctic continent. Unfortunately…
Background: Poorly preserved biological tissues have become an important source of DNA for … a wide range of zoological studies. Measuring the quality of DNA obtained from these samples is … often desired; however…
