The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a newly-constituted international treaty that as yet may be little … known to marine ornithologists around the world. We outline the rationale for the existence of the Agreement, the history of its development…
Length-at-age data for Patagonian toothfi sh (Dissostichus eleginoides) at Heard Island … (Division 58.5.2) were fi tted using a von Bertalanffy (VB) growth model taking into … account response-biased sampling of fi sh that were aged. Subsampling of random lengthfrequency … (LF)…
[1] In September–October 2005, the juxtaposition of low- and high-pressure anomalies at … 130W and 60W, respectively, created strong and persistent northerly airflow across the … West Antarctic Peninsula (WAP). This had a major impact on regional sea ice conditions…
For wildlife managers, determining inter-species differences in the behavioral responses of seabirds to visitation can allow … greater efficacy of visitor guidelines. Two key management outcomes for such information include 1)…
A new ground-based technique for estimating … the density of nesting Adélie penguins (Pygoscelis adeliae) within occupied habitat is described and evaluated using an … experimental approach with model penguins. In this set-up…
Law Dome is situated in East Antarctica, and is a relatively high elevation … coastal site, with an ice core record spanning approximately 80,000 years. It … receives high snow accumulation and is situated on the most northerly … coastline in Antarctica (apart from the tip of the Peninsula)…
Fast ice makes up about 10 % by area (or 14 - 20 % by volume) of the total … Antarctic pack. Its growth is largely determined by thermodynamics processes, which makes it a valuable tool to monitor changes in the polar climate system. Time series of fast-ice properties…
Ozone climatologies are presented for a number of locations in the Australian region, making use of … both total ozone and ozone profile data, as measured by the Bureau of Meteorology’s Dobson and … ozonesonde networks. For mid-latitude sites (Melbourne and Macquarie Island)…
Understanding and characterising the variability of ozone in the lower atmosphere is a key aspect of … regional and global climate assessment. Tropospheric ozone influences climate by absorbing outgoing … longwave terrestrial radiation, thereby acting as a greenhouse gas…
In September 2007, a multi-disciplinary sea-ice voyage, jointly organised by the Australian Government Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Centre, sailed from Hobart. The focus of the Sea Ice Physics and Ecosystems Experiment (SIPEX)…
The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is bound by … its Article II, 3 to follow an ecosystem approach to management. This approach has been extended to … the application of a precautionary approach in the late 1980s. In our review…
The size-differentiated sex ratio (proportion of males, PM) of Antarctic krill Euphausia … superba was examined with an extensive dataset derived from scientific surveys in the Indian Ocean … sector and the southwest Atlantic sector, and from the krill fishery in the Southern Ocean.
Abstract. We examined sexual dimorphism in 11 morphological characters of the Flesh-footed Shearwater (Puffinus … carneipes) and used these characters in a discriminant function analysis (DFA) to enable sexual classification in the field.
Chlorophyll fluorescence was used to measure changes in the maximum fluorescence yield (F0m) and effective quantum yield (F/F0m ) of Antarctic macroalgae in response to dissolved copper.
Populations of Southern Rockhopper ( Euduptes chrysocome chrysocome … ) and Macaroni ( E. chrysolophus … ) Penguins at key breeding sites in the Southern Hemisphere have declined substantially in the past 50 years, but … their statuses at important breeding sites in southern Chile are poorly known.
The invertebrate fauna of many Antarctic … ice-free areas, even those close to permanent research … stations, can be poorly known. Here we describe some … nematodes from freshwater and saline, marine-derived … lakes of the Vestfold Hills, East Antarctica.
On 20 January 2005 the sun produced the highest intensity of relativistic … solar particles observed at Earth in 50 years. The sea-level increase at Terre Adelie … (~46 X in 1 minute data) was slightly less than in 1956 (Leeds ~47 X in 15 minute … data).
Blue-dyed bait is a seabird bycatch mitigation technique which is assumed to reduce the … contrast between the bait and the ocean background making baits visually cryptic to seabirds. We tested this assumption in two ways. First, using measured spectral profiles of blue-dyed … baits (fish and squid)…
Ship-borne and airborne infrared radiometric measurements during the ARISE cruise of September–October 2003 permitted in situ validation studies of two satellite-based ice surface skin temperature algorithms:
