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…
A field trial for removal of dissolved metal contaminants in water from an abandoned waste disposal site, using ion-exchange … columns of an iminodiacetic acid chelating ion-exchange (IDA) resin, was conducted at Casey Station, Antarctica. An on-site … monitoring technique…
Salinity and lowtemperature effects on adsorption of contaminant metals from … water using an iminodiacetic acid (IDA) ion-exchange resin, were investigated under … dynamic flow conditions. The order of selectivity of the resin (20°C and 0% seawater) was: Cu2+Pb2+Cr3+ Ni2+Cd2+Zn2+ Low temperature…
I on exchange characteristics of Cu2þ on the natural zeolite clinoptilolite at 2 and 228C are … presented to facilitate the development of a permeable reactive barrier (PRB) to treat … heavy-metal contaminated waters in Antarctica.
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…
Sludge reduction and dewatering is an important aspect of water and waste water treatment. This is especially true in the case of … Australia’s Antarctic contaminated site remediation program…
Water collection and treatment is often required for effective cold regions contaminated site clean-up, where large volumes of … meltwater runoff might otherwise become contaminated during remediation activities and disperse pollutants into the surrounding … environment.
Two terrestrial Crustacea, Puhuruhuru patersoni (Amphipoda: Talitridae) and Styloniscus otakensis … (Isopoda: Styloniscidae), were discovered on sub-Antarctic Macquarie Island in 1991 and 1992, respectively. Each … species was identified as having been described, and previously only known…
Measurements of atmospheric trace gas composition from times before reliable direct observations began in the late 20th century come from air enclosed in polar ice and firn. This presentation will review the evidence for changes in atmospheric CO2…
Lowest temperature and snow accumulation rate are preconditions for retrieving the oldest ice core … from the polar ice sheets. The 10-m depth firn temperature at Dome A, the summit of the Antarctic Ice … Sheet, recorded by an automatic weather station (AWS) was −58.3 in 2005 and −58.2 in 2006…
An extensive Pb isotope ratio survey of ∼100 marine sediment samples from near Casey … Station, East Antarctica has been undertaken. Sediment surface grabs and cores were … collected over nine years between 1997–2006 and, following HF total digestion, were … analysed by magnetic sector ICP-MS.
A method is described for determining the relative extent of weathering in moderately biodegraded, hydrocarboncontaminated … soils from Antarctica. Plotting the pristane diastereomer ratio (PrDR) vs. pristane/phytane (Pr/Ph) allows … the relative extent of weathering…
Radar observations of the winds above the Antarctic coast have been … underway since 1968 using meteor (Molodezhnaya, 45.9E, 67.75) and MF … (Mawson 62.9E 67.65, Davis 78.0E, 68.65) radars. Comparisons between … concurrent observations from Moldezhnaya and Mawson…
1. Previous studies of Antarctic clonal moss populations using RAPD markers have reported … extraordinarily high levels of genetic variation. This has been claimed to reflect somatic mutation, possibly resulting from elevated UV-B radiation. 2.
