Background … Satellite tags were deployed on 50 east Australian humpback whales (breeding stock E1) between 2008 and 2010 on their southward migration, northward migration and feeding grounds in order to identify and describe migratory pathways, feeding grounds and possible calving areas.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
In response to a report of the incidental mortality of three juvenile humpback whales in the Antarctic … krill trawl fishery in Subareas 48.1 and 48.2 during the 2021 calendar year, SC-CAMLR reconvened … the Working Group on Incidental Mortality Associated with Fishing (WG-IMAF).
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…
The ANGWIN Antarctic Gravity Wave Instrument Network has the ability to measure gravity-wave characteristics at various locations and height ranges.
The ANGWIN Antarctic Gravity Wave Instrument Network has the ability to measure gravity-wave characteristics at various locations and height ranges.
The Australian Antarctic Division (AAD)1 is undertaking planning activities for a proposal to construct and operate a new aerodrome near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project). The Davis Aerodrome Project would involve the construction of a 2.
This Information Paper supplements Working Paper 43 by setting out draft criteria that might be applied to identified Important Bird Areas (IBAs) as well as to other bird colonies or aggregations1 when considering ASPA designation.
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)…
Australia has decided not to proceed with a proposal to construct and operate a paved runway near Davis research station in the Vestfold Hills, East Antarctica (the Davis Aerodrome Project), following careful consideration of the likely environmental impact, cost and complexity of the project.
There is growing evidence that the Antarctic is increasingly exposed to chemical stressors. Antarctica is impacted by global issues such as climate change and long-range transport of chemicals. Furthermore, expanding tourism and research activities…
This paper provides an update to the ATCM on the implementation of Resolution 8 (2021) Antarctica in Changing Climate, one year after its adoption.
As the ATCM was sadly cancelled in 2020, in light of the global Covid-19 pandemic, ATCMXLIII in 2021 is the first meeting of the Parties since the publication of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The SROCC…
Every living organism sheds its DNA into the environment, leaving an invisible record of its presence. However, scientists have found ways to magnify this environmental DNA or 'eDNA' from water, soil and other environmental samples, allowing them to identify who the DNA belonged to.
Snow is a crucial and integral component of the sea ice system. It insulates the ice to retard the rate of thermodynamic ice thickening. At the same time, it contributes directly to sea-ice thickening through snow-ice formation…
The relationships between flying Antarctic seabirds and their at-sea environments remain poorly understood, particularly outside of the breeding season. Improving our knowledge of how these marine predators use their habitat is a critical step towards conservation of these species.
Polar oceans and sea ice cover 15% of the Earth's ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmosphere Study (SOLAS) project key focus…
Ecosystem dynamics at the northwest Antarctic Peninsula are driven by interactions between physical and biological processes. For example, baleen whale populations are recovering from commercial harvesting against the backdrop of rapid climate change…
Marine migratory species tend to be overlooked in marine spatial planning due to limited knowledge of their habitats and migration pathways, resulting in a disconnect between animal migration ecology and spatial management decision making.
The fin whale is listed as globally vulnerable, with ongoing threats to their population, yet little is known about the distribution and movements of the Southern Hemisphere sub-species, Balaenoptera physalus quoyi.
The fine-scale distribution of pelagic forage fish is shaped by competing factors as fish optimise foraging while avoiding predation.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the ‘2018–19 Area 48 Survey’.
Supporting Antarctic scientific investigation is the job of the national Antarctic programmes, the government entities charged with delivering their countries’ Antarctic research strategies. This requires sustained investment in people, innovative technologies, Antarctic infrastructures…
Sea ice kinematics impacts the global ocean–atmosphere system in numerous ways: modification of albedo, ice cover, and ice mass; heat transmission between atmosphere and ocean; and ice thickness distribution.
