The internal structure of the Law Dome ice cap is being investigated by studying ice cores obtained from several sites along the summit - Cape Folger line. Profiles of measured physical properties for four of the ice cores from near the margin of the ice cap are presented.
Significant changes in zooplankton composition have occurred in various ocean systems in … recent years. These changes can be quite dramatic, occurring within one or two seasons, as … happened with the regime shift in the North Sea and North Atlantic in the late 1980s.
The effects of ultra-violet radiation (UVR) stress on the growth, biochemical … composition and fatty acid profiles of four Antarctic microalgae from the University of Malaya Algae … Culture Collection (UMACC) were investigated. The microalgae studied were Chlamydomonas UMACC … 229…
The growth, biochemical composition and fatty acid profiles of six Antarctic microalgae cultured at different … temperatures, ranging from 4, 6, 9, 14, 20 to 30 ◦C, were compared. The algae were isolated from seawater, freshwater…
Mark-recapture models applied to double-observer distance sampling data neglect the information … on relative detectability of objects contained in the distribution of observed distances.
Nearly 36,000 vertical temperature profiles collected by 15 king penguins are used to map oceanographic fronts south of … New Zealand. There is good correspondence between Antarctic Circumpolar Current (ACC)…
Abstract … Little effort has been devoted to differentiating between hydrocarbon losses through evaporation and biodegradation … in treatability studies of fuel-contaminated Antarctic soils. When natural attenuation is being considered as a treatment … option…
The Southern Hemisphere westerlies in the southwest Pacific are known to have waxed and waned numerous times during the last … two glacial cycles, though even semi-continuous histories of the westerlies extend back no more than about 20,000 years.
Industrial longline fisheries are considered worldwide as the main threat to albatross and … petrel populations, particularly at open oceans. However, inside countries’ EEZ artisanal … fleets account for a significant fishing effort and eventually…
Polar Mesosphere Summer Echoes (PMSE) were detected above the high-latitude station Davis, Antarctica (68.61S) using a 55MHz atmospheric radar during the 2003–2004 austral summer. In this paper…
To examine the potential of lipids as dietary markers in Euphausia superba Dana, juvenile … krill were fed 4 phytoplankton diets (diatoms, cryptomonads, dinoflagellates and thraustochytrids … over a range of food concentrations) and 2 species of zooplankton (rotifers and Artemia sp.) for 20 d.
Two phytoplankton diets with markedly different fatty acid (FA) profiles (thraustochytrid … and diatom over a range of concentrations) were fed to juvenile Euphausia superba Dana to … evaluate the time lapse required for the development of trophic lipid signatures in the digestive gland … (DG).
Spatio-temporal variability of zooplankton community structure off east Antarctica (90 to 160°E) was studied from 1988 to 1996 based on samples collected by the Japanese icebreaker Shirase. Three community groups with distinctive species compositions were obtained by cluster analysis.
Abstract: Austrochlamys heardensis (Fleming) is recorded from a boulder of Late Pliocene (3.62–2.5 Ma) volcaniclastic sandstone dredged 70 km east-north-east of Heard Island, the third record of the species.
Antarctica’s Lambert graben, Australia’s North West Shelf, and the eastern Indian Peninsula all host thick, fault-bounded … Permian-Triassic successions. These terranes were adjacent to each … other in Gondwana. The Lambert graben intersects the modern … coastline…
Antarctic coastal krill (Euphausia crystallorophias) were collected in Austral winter (July/August) 1999 in the Mertz … Glacier polynya off the coast of East Antarctica and were compared to krill collected off East Antarctica during … summer in 1996 and 2001 and spring 1999.
Abstract. Due to the typical high atmospheric noise and low opacity, submillimeter observations … can be carried out only from sites with very high atmospheric stability and very … low precipitable water vapour content.
