The demographic performance of high level antarctic predators is ultimately determined by the oceanic processes that influence the spatial and temporal distribution of primary productivity.
Sediment and water budgets for selected lakes in the Larsemann Hills, Eastern Antarctica. The lakes of the Larsemann Hills are almost all freshwater and have a number of characteristics that distinguish them from the lakes in other Antarctic Oases.
Analysis of polar ice cores is commonly used to produce records of climatic conditions in the past.
The lakes and fjords of the Vestfold Hills region of Antarctica provide unique ecosystems for studying environmental changes in Antarctica over the past 8000 years.
Marine sediments are important regulators in global biogeochemical and atmospheric cycles.
Most of the snow falling on inland Antarctica drains via large ice streams and floating ice shelves to the sea where it lost by iceberg calving or as melt beneath the shelves. Ocean interaction beneath the shelves is complicated, and regions of basal refreezing as well as melt occur.
Petroleum contamination poses a major threat to Antarctic ecosystems because petroleum products are persistent and potentially toxic in the environment. Natural attenuation of most fuels and oils that are commonly used in Antarctica is very slow (decades or longer).
The aim of this project is to determine how feasible it is to regularly sample the pelagic under-ice community during winter at a coastal site near Mawson.
