Life beneath the ice sheets of Antarctica
28 July 2009
Geoscience Australia geologist Dr Alix Post recently participated in Fresh Science 2009. Fresh Science is an annual national media competition and training program that highlights new and interesting research being undertaken by early-career scientists from around Australia.
Dr Post presented research on the history of colonisation of a unique 9000 year old seafloor ecosystem found beneath the Amery Ice Sheet in east Antarctica. Scientists from Geoscience Australia, working in collaboration with the Australian Antarctic Division, studied the sediment samples to determine their age and to look for clues to changes in the environment over time. They also studied shell fossils within the core samples looking for clues about changes in the environment over time.
Studying habitats such as these can help to improve understanding about changes in species diversity over time, and allow us insight into how ecosystems are able to survive and prosper in such hostile environments.
Further information about Dr Post's work is available on the Fresh Science website.
