The Mount Brown South ice core (MBS 69.111S 86.312E) is a new, high resolution ice core drilled in coastal East Antarctica. With mean annual accumulation estimated to be ~30 cm ice equivalent throughout the length of the core (~290 m)…
Global fungal diversity is estimated to range in the millions, yet it remains severely underexplored, especially in extreme environments. Fewer than 5% of species have been officially identified and characterised. Estimates suggest that 70%–90% of soil fungi remain uncultivable…
Groundwater response to climate variations is often pivotal to managing groundwater sustainably. However, this relationship is rarely explicitly examined because of the complexity of surface to subsurface processes and the diverse impacts of multiple drivers…
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (?precip), meteoric water (?MW) and seawater (?SW)…
Gases released by human activity (greenhouse and ozone depleting gases) are responsible for global change. They are long-lived and well-mixed in the atmosphere. The Antarctic regions, remote from industrial and land plant activity are ideally located to measure global changes in the gases.
In situ chemical oxidation (ICO) has been identified as a potential technology for the remediation of petroleum hydrocarbon contaminated sites in Antarctica.
A climatology of hydroxyl (6-2) band temperatures has been derived from 15 consecutive years of scanning … spectrometer measurements at Davis station (68°S, 78°E), Antarctica.
The effect of different light regimes on physiological parameters (feeding activity, oxygen consumption, and … activity of the metabolic enzyme malate dehydrogenase [MDH]) of Antarctic krill, Euphausia superba, was studied … over 12 weeks under laboratory conditions.
A chelating ion-exchange resin, Rhom and Haas Amberlite IRC 748, was investigated for the exchange of … copper and sodium from aqueous solutions at four different temperatures. A two-parameter temperaturedependent…
Research and data collection over several years has allowed us to determine the best alternative energy option for Australian stations. This is to install a small number of large commercially available, minimally modified wind-turbines. They would be variable-speed, 280kW machines without gearboxes…
Six ice cores were collected during the 1997/1998 summer season along the 2000 m contour of Wilhelm II Land (ASAC 2085), followed by fifteen cores the following season from the 1800, 1500 and 1000 m contours in the same area (ASAC 1109)…
A GPS network has been installed to monitor vertical crustal movement … in the Lambert Glacier region, East Antarctica. The program … commenced in January 1998 with a solar-powered GPS system installed at … Beaver Lake.
The development of a semi-automated batch HG-AFS method for the shipboard determination of As(III), As(V), MMA and DMA is described. Procedures in the analytical sequence including addition of NaBH4 to samples, cooling and heating the U-trap used for preconcentration and separation of the arsines…
Surface sediments (0-25 cm) from Ace Lake (eastern Antarctica), a saline euxinic lake, were analyzed to study the early incorporation of reduced inorganic sulfur species into organic matter. The apolar fractions were shown to consist predominantly of dimeric (poly)sulfide linked C-27-C-29 steroids.
The borehole BHQ, 430 m deep, was drilled in Law Dome, Antarctica, by the Australian National Antarctic Research Expedition in 1977. The core from BHQ was estimated to contain ice layers for about 5000 a, and was sent partly to China in 1983 for studies in detail.
Two series of mutant polypeptides of the type I, 37 residue winter flounder antifreeze protein have been synthesized and analyzed by nanoliter osmometry, the ice hemisphere test, measurement of ice growth hysteresis and circular dichroism spectroscopy.
