Petroleum contamination poses a major threat to Antarctic and subantarctic ecosystems because diesel and lubricants are persistent and, at poorly defined concentrations, are toxic in marine environments.
Can animals raft between countries on floating seaweed? We aim to answer that question using powerful genetic tools.
The abundance of sediment-living communities in the impacted marine bay adjacent to Casey Station is related to sediment metal concentrations, particularly tin, lead, copper, cadmium and iron.
This proposal describes an exciting new initiative for Coordinated Research into Antarctic Calving (CRAC) on the Amery Ice Shelf during the International Polar Year (IPY) in 2007-09. CRAC's particular emphasis will be on studying the calving of tabular icebergs, a process which…
IPY Aliens in Antarctica will assess the threat of humans carrying non-native seeds and spores into Antarctica. We will identify routes of transport and attempt to calculate how many seeds and spores are transported each year.
This research will contribute to a large multi-disciplinary study of the physics and biology of the Antarctic sea ice zone in early Spring 2007. The physical characteristics of the sea ice will be directly measured using satellite-tracked drifting buoys, ice core analysis and drilled measurements…
Micronutrient trace elements exert an important influence on the growth and activity of microscopic life-forms in Southern Ocean surface waters. They in turn govern the drawdown of atmospheric carbon dioxide, a major factor in global climate change.
We will conduct a genomic analysis of Archaea and Bacteria collected from lakes in the Vestfold Hills, Antarctica. This will provide a new level of understanding about the life forms inhabiting these cold lakes.
The aim of this multi-disciplinary proposal is to examine the molecular evolution of toxic proteins across the full taxonomical spectrum of venomous Antarctic marine animals.
The temporal and spatial variations of penguin and seal populations and their colonies, the relationship between the ecology of penguin, seal and environmental factors, and the biogeochemical cycles of C, N, P in penguin colony ecosystem.
