Polyhydroxyalkanoate (PHA) is a family of biopolymers produced by some bacteria and is accumulated intracellularly as carbon and energy storage material. Fifteen PHA-producing bacterial strains were identified from bacteria isolated from Antarctic soils collected around Casey Station (66°17'S…
Sea ice plays an important role in ocean–atmosphere heat exchange, global albedo and the marine ecosystem. Knowledge of variation in sea-ice extent is essential in order to understand past climates, and to model possible future climate scenarios.
A consequence of the wave-number rich tidal activity that has been observed in the southern polar MLT is that the horizontal flux of horizontal momentum (u'v') is likely to be non-zero. This quantity is affected by the phase angle between the zonal and meridional wind perturbations.
Abandoned work sites, disposal sites, hazardous waste and untreated fuel spills in Antarctica have … recently begun to receive significant attention. A profile of the clean-up at Casey waste disposal site demonstrates a suite of cultural, social…
We review the scientific literature, especially from the past decade, on the impacts of human … activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and … temporal scales.
Sensitive analytical techniques are typically required when dealing with samples from Antarctica as even … low concentrations of contaminants can have detrimental environmental effects. Magnetic Sector ICP-MS is … an ideal technique for environmental assessment as it offers high sensitivity…
