Limnological and nearshore diatom communities of Macquarie Island: proxies of subantarctic climate change? MCMINN, Prof. Andrew Macquarie Island

Macquarie Island offers scientists a unique laboratory for investigating subantarctic climate change.

An integrated survey of the waters between 30 and 80 degrees East (CCAMLR Division 58.4.2) NICOL, Dr Stephen (Steve) Marine Science

A planned acoustic biomass survey for krill in CCAMLR Division 58.4.2 (South West Indian Ocean) in January-March 2006 will produce the data for a revised catch limit on the krill fishery.

What factors control bacterial biodiversity in a natural marine derived Antarctic laboratory? LAYBOURN-PARRY, Prof. Johanna (Jo) Davis

We propose investigating bacterial biodiversity and the factors that have shaped biodiversity in a natural marine derived laboratory – the saline lakes of the Vestfold Hills.

Fracturing and deformation along the Amery Ice Shelf COLEMAN, Prof. Richard Amery Ice Shelf, Davis

The break-up of Antarctic ice shelves has highlighted the need for a better understanding of the dominant fracture processes occurring within the ice shelves and whether there is any link to climate variability.

The hydraulic behaviour of Permeable Reactive Barrier materials under freeze-thaw conditions GORE, Prof. Damian Australia (or home country), Casey

Permeable Reactive Barriers (PRB), planned for remediation of contaminated sites near Casey Station, contain granular fillings. Freezing and thawing of granular materials can create subsurface channels that allow rapid throughflow of water and contaminants.

Heavy metal concentrations and isotope ratios in Law Dome snow as indicators of recent climatic and environmental variability ROSMAN, Prof. Kevin Australia (or home country), Casey, Law Dome

The widespread use of lead since antiquity has left an indelible mark on the Northern Hemisphere polar ice archives in Greenland. Using its isotopes this lead was traced to emissions from early Roman mining and smelting operations in southern Spain.

Heard Island 2003/04: Terrestrial Biology: Carbon acquisition and nitrogen economy of Heard Island plants as affected by climate change SCHORTEMEYER, Dr Marcus HIMI

Recent global warming has become evident on Heard Island, where sea temperatures have risen by 1°C over the last 50 years, and glaciers are rapidly retreating. Rising temperatures affect photosynthesis and respiration, and ultimately growth, of plants.

Selenium as a key micronutrient in primary productivity in the Southern Ocean BUTLER, Dr Edward Marine Science

Selenium will be studied in the Southern Ocean to learn of its role as a trace nutrient for microalgae and, therefore, as a possible regulator of carbon cycling in these waters.

Occurrence of eukariotic microbial, fungi and oomycoty from extreme environments ALIAS, Dr Siti Macquarie Island, Petersen Island, Ardery and Odbert Islands ASPA, Balaena Island, Casey, Snyder Rocks, Wilkes Land Coast

The project aims to study the diversity of Antarctic fungi and the protist. Comparison with the tropical species will be made based on their morphological, physiological, biochemical and molecular charateristics.

Three-dimensional microscale distribution and production of plankton populations SEURONT, Dr Laurent Marine Science

This project investigates how the microscale three-dimensional distribution of viruses, bacteria and phytoplankton, and the production/respiration rates of the microplankton community in the Southern Ocean varies with viscosity and nutrient concentrations…
