Taking the Antarctic Arctic Polar Pulse-IPY 2007-8 (TTAAPP) Human Biology and Medicine Research AYTON, Dr Jeffrey (Jeff) Casey, Davis, Macquarie Island, Marine Science, Mawson

The IPY 2007-2008 provides a unique opportunity to create a human polar observatory and enhance our capacity to develop an innovative multinational and multidisciplinary Polar Health Surveillance System (PHSS) utilising synergies of existing national polar research programs…

Further elucidation of the freshwater fauna of the Australian Antarctic Territories DARTNALL, Dr Herbert (Herb) Davis, Vestfold Hills, Prince Charles Mountains, Beaver Lake, Casey, Framnes Mountains, Mawson, NE Bailey Peninsula ASPA, Australia (or home country), Mawson's Hut ASPA

Collections are to be made at Casey Station and at other specified areas within the Australian Antarctic Territories to expand our knowledge of the freshwater fauna.

Review of vegetation recovery from human impacts SELKIRK, Dr Patricia Casey

Recent observations suggest there has been substantial recovery of lichens in areas previously affected by alkaline cement dust and physical activity at Casey Station. This project will re-examine two 1989/90 study and control sites to evaluate the extent of vegetation recovery over two decades.

Modelling and mapping near-shore fast ice distributions and dynamics: a spatial perspective LUCIEER, Prof. Arko Australia (or home country), Casey, Macquarie Island

One of the aims of the Human Impacts Program is to understand the natural variability of coastal Antarctic marine communities and how they might relate to the varying environmental conditions of light, sea ice, water quality and sedimentation to assess the effects of human impacts.

Enigmatic Orogeny during the dispersal of Rodinia: Deciphering the Record of Tectonic Reworking in the Vestfold Hills COLLINS, Dr Alan Davis, Rauer Islands, Vestfold Hills

The Neoproterozoic was a time of extreme climate change, extra-terrestrial bombardment, furious biotic evolution and continent re-organisation. We don't fully understand what linked these events and processes and, surprisingly, we don't even really know the geography of the planet during this time.

Remote sensing for mapping and monitoring vegetation on Heard Island LUCIEER, Prof. Arko Australia (or home country)

Heard Island's pristine and rapidly changing environment makes it a relevant and exciting location to study the effects of global climate change on its subantarctic vegetation. This study will use satellite imagery to map vegetation types.

Development of geophysical methods for the study of contaminant transport in frozen ground ROACH, Dr Michael (Mike) Australia (or home country), Casey

This project will improve the understanding of pathways and mechanisms in contaminant transport in seasonally frozen ground by application of detailed geophysical methods at a known hydrocarbon spill and a former waste disposal site in the Australian Antarctic.

An integrated study of processes linking sea ice and biological ecosystem elements off East Antarctica during winter MEINERS, Dr Klaus Marine Science

A planned multidisciplinary survey of the processes linking sea ice with biological elements of Antarctic marine ecosystems will be conducted in winter 2007.

Molecular analysis of microbiota trapped in ancient antarctic glacial ice BOWMAN, Dr John Australia (or home country), Casey

Ancient Antarctic glacial ice is a potential resource of trapped microorganisms dating back several hundreds of thousand years that give a snapshot of the past.

Responses and adaptations by two seal species to variability in the Southern Ocean ecosystem HINDELL, Prof. Mark Australia (or home country), Casey, Davis, Vestfold Hills

Weddell and southern elephant seals are high-order predators living in the Antarctic marine ecosystem. Their place in that ecosystem is the result of a long history of evolutionary adaptation to a challenging and changing environment.
