Tide gauges remain the fundamental instrument used to measure water level in the coastal environment. Issues … surrounding the calibration and vertical datum control of tide gauges are therefore fundamental in studies involving … the determination of absolute sea level and its variation over time.
A high-resolution, offline ocean general circulation model, incorporating a realistic parameterization of … mixed layer convection, is used to diagnose pathways and time scales of Southern Hemisphere intermediate, mode, and lower thermocline water ventilation.
This paper presents results on modeling the ground-level response of the higher energy protons for the 2005 … January 20 ground-level enhancement (GLE). This event, known as GLE 69, produced the highest intensity of relativistic … solar particles since the famous event on 1956 February 23.
Between January and April over six consecutive years (2000 to 2005) photographs of the … dorsal fin and lateral bodies of pygmy blue whales (Balaenoptera musculus brevicauda) were … collected at the Perth Canyon, Western Australia.
The application of blue-dye to fishing baits is a seabird bycatch mitigation technique used … in some pelagic longline fisheries that is thought to make the baits less visible and hence … less attractive to seabirds. We tested this assumption in two ways. First…
The Antarctic Biodiversity Database developed and hosted by the Australian Antarctic Data Centre (AADC), holds data and information on Antarctic and subantarctic flora and fauna in support of the SCAR Life Sciences programme Evolution and Biodiversity in the Antarctic (EBA).
Seismic anisotropy is investigated across the previously unstudied region of central East Antarctica including new coastal locations and remote, temporary stations far inland.
A conceptual, lithospheric-scale cross-section of the conjugate, oblique-slip margins of George V Land, East … Antarctica, and southeast Australia (Otway Basin) has been constructed based on the integration of seismic and sample … data.
Abstract Isotoma klovstadi Carpenter, 1902 was one of … the first Collembola described from the Antarctic continent. It was first collected in November 1899 during the … British Antarctic Expedition on the north coast of Victoria … Land in the Ross Sea region.
Throughout the Southern Hemisphere many terrestrial taxa have circum-Antarctic distributions. This pattern is generally … attributed to ongoing dispersal (by wind, water, or migrating birds) or relict Gondwanan distributions. Few of these … terrestrial taxa have extant representatives in Antarctica…
Hybridization among organisms can potentially contribute to the processes of evolution, but this depends on the fitness of hybrids relative to parental species. A small, recently … formed population of fur seals on subantarctic Macquarie Island contains a high proportion … of hybrids (17–30%)…
Human impacts on natural systems can cause local population extinctions, which may promote … redistribution of taxa and secondary contact between divergent lineages. In mammalian … populations that have mating systems shaped by polygyny and sexual selection…
the glaciation and isolation of the Antarctic continent completed by ~10 million years ago, and not by the sequential break-up of Gondwana (completed by ~32 million years ago). More recently…
Abstract. An eddying global model is used to study the characteristics … of the Antarctic Circumpolar Current (ACC) in a … streamline-following framework. Previous model-based estimates … of the meridional circulation were calculated using … zonal averages:
We reexamine the relationship between circulation, bathymetry, and surface … chlorophyll in the Southern Ocean, using new high-resolution maps of the frontal structure … of the Antarctic Circumpolar Current (ACC) derived from satellite altimetry.
Repeat hydrographic sections occupied in 1995 and … 2005 reveal a rapid decline in the salinity and density of … Antarctic Bottom Water throughout the Australian Antarctic … Basin. The basin-wide shift of the deep potential … temperature-salinity (qS)…
We describe the circulation and seasonal development of the upper ocean … in the Seasonal Ice Zone (SIZ) of the Southern Ocean along 140°E. The 140°E section … was repeated four times between November 2001 and March 2002, spanning the period … from early spring to autumn.
The quasi-stationary asymmetry of total ozone … over Antarctica during spring is studied by TOMS data during … the period 1979–2005.
The Mansurov effect, which for the Southern Hemisphere consists of a positive … association between the By component (east-west) of the interplanetary magnetic field … (IMF) and the ground-level pressure for stations poleward of 80 magnetic latitude, is … confirmed for Vostok (78.5S, 106.
Extreme solar processes at the Sun on 2001April 15 accelerated protons to relativistic energies, resulting in a groundlevel … enhancement in cosmic rays observed at Earth. The GOES 10 spacecraft measured the proton flux directly…
Ice sheet modelling of Antarctica supports a generally accepted view that most, if not all, currently ice free ground would have been obliterated at the LGM or previous maxima. However…
Effects of salinity and low temperature on the removal of dissolved contaminant … metals from water by an iminodiacetic acid (IDA) ion-exchange resin, Amberlite … IRC748, were investigated under batch equilibrium conditions. As expected for ions … retained by chelation…
