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).
[1] We analyzed d29Si of dissolved silicate for eight water column profiles across the … Southern Ocean (south of Australia in spring 2001) from the Seasonal Ice Zone (SIZ) north to the Subantarctic Zone (SAZ), including the first isotopic compositions measured … for Si-depleted seawaters.
Induction magnetometer data recorded at three closely spaced sites (110km) in Antarctica (mlat -75°) have been examined for ionospheric signatures of the outer magnetosphere and cusp/cleft regions. Cross-phase analysis of the 1–10 mHz band…
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…
ABSTRACT: Predictive species–environment models have numerous ecological and management applications, and can provide insight into the functional relationships between a species and its environment.
On sub-Antarctic Macquarie Island, we examined pup weaning mass of southern elephant seals in relation to human presence. Pup weaning mass was previously found to be positively associated with 1st-year survivorship. Weaned pups were weighed in a remote area, Middle Beach…
An experiment was conducted on an autoline longline vessel to derive a sink rate, and line weighting regime, that would minimise the capture of albatrosses based on knowledge of line sink rates and albatross diving abilities. Sink rates of lines deployed into propeller turbulence…
Abstract: Data on the response behaviour of seals (crabeater, leopard and Ross) and penguins (Ad¨¦lie and … emperor) to helicopter surveys over the pack ice off East Antarctica are presented.
A solid-phase extraction method based on an ion-exchange retention mechanism … has been used for in-line preconcentration of inorganic anions prior to … their separation by capillary electrophoresis (CE).
We combine ERS-1 satellite radar altimeter surface elevations (Fricker and others, this issue) with six different accumulation distributions to compute balance fluxes for the Lambert Glacier-Amery Ice Shelf Drainage system.
Photometric intensity measurements of the OH(6-2) band P1(2), P1(3), P1(4) and P1(5) emissions were collected at a four minute repetition rate at Davis station, Antarctica during 1994. These data are being examined to determine the magnitude…
Digital magnetometer data have been collected from Davis (68.58°S, 78.0°E) since 16 February 1988 and from Casey (66.28°S, 110.5°E) since 17 January 1989. The processing of the variometer data from Casey has been transferred to the Australian Geological Survey Organisation (AGSO)…
Pc3-4 pulsations observed at high-latitudes have been examined for evidence of magnetic field line resonances. Previous studies have suggested that these pulsations are due to harmonics of the lower frequency Pc5 pulsations.
High-resolution Fabry-Perot spectrometer observations of the OH(62) Q1(1) line, l834.46 nm, were made at Mawson, 67.6ºS 62.9ºE, and Davis, 68.6ºS 78.0ºE, Antarctica, in 1997. The observing program resulted in three sets of continuous OH observations suitable for tidal analysis: July 25…
