Relationships between size, body condition, age and feeding-attendance patterns during pup rearing of female Antacrtic fur seals Arctocephalus gazella and their effects on the timing of birth and weaning, pup […]
The effects of low temperatures, freezing and desiccation on a cyanobacterium (Phormidium) and an alga (Prasiola) from terrestrial Antarctic habitats were investigated. Net photosynthesis per unit dry weight, measured by […]
The number of Antarctic fur seals (Arctocephalus gazella) in the area of the Scotia Sea has been increasing. Observation of their distribution on the breeding grounds are important to help […]
Ice rheology governs how glaciers flow and respond to environmental change. The rheology of glacier ice evolves in response to a variety of mechanisms, including damage, heating, melting and the […]
The phase-sensitive radio-echo sounder (pRES) is a powerful new instrument that can measure the depth of internal layers and the glacier bed to millimetre accuracy. We use a stationary 16-antenna […]
The Southern Ocean is a pivotal component of the global climate system yet it is poorly represented in climate models, with significant biases in upper-ocean temperatures, clouds and winds. Combining […]
Investigators have used the temporal record of heavy metal and sulphur concentrations in Antarctic snow to assess the extent of global atmospheric pollution in the Southern Hemisphere. These studies would […]
Environmental impact assessment (EIA) is generally recognized as a useful tool in reducing human impacts on the environment. The Antarctic environment is especially sensitive to harmful perturbation. Regulations introduced under […]
The presence of hemolymph thermal hysteresis antifreeze proteins is described in both the nymphs and adults of the Antarctic oribatid mite, Alaskozetes antarcticus collected from Signy Island in the South […]
