In situ chemical oxidation (ICO) has been identified as a potential technology for the remediation of petroleum hydrocarbon contaminated sites in Antarctica.
A comparison is made of results for barotropic, surface and abyssal flows during the formation and … passage of a warm-core ring in the East Australian Current. The barotropic velocities are estimated from … sea-floor measurements of the horizontal electric field, which is induced by water motion.
A series of nutrient-amended microcosms was used to investigate changing microbial communities during biodegradation in … hydrocarbon-contaminated Antarctic soils at 4, 10 and 42 °C. Although sample heterogeneity resulted in no statistically significant … reduction in total petroleum hydrocarbons…
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…
Australia’s Antarctic territory contains several hydrocarbon-contaminated sites of varying size and severity as a result of fifty years of human activities in the region. Contaminated site remediation in Antarctica is more challenging than in Australia.
Improved testing and remediation procedures for sites … contaminated with petroleum hydrocarbons are a priority … in remote cold regions such as Antarctica, where costs are … higher and remediation times are longer.
Natural attenuation of petroleum hydrocarbons in polar and subpolar soils is limited by low nutrients, low temperatures, and … water availability.
Many contaminated cold region soils are deficient in nitrogen, and addition of the proper amount of this nutrient can increase the biodegradation rate. However…
