Dr Pauline Treble
Staff Profile
Role at ANSTO
Pauline's research is focused on reconstructing climate using geochemical data such as oxygen isotopes and trace metals preserved in cave stalagmites. This information serves as an archive of past changes in rainfall and temperature.
Her current projects are focused on caves in the southwest of Western Australia and the NSW Snowy Mountains. These are key areas currently facing water shortages and for which longer-term records of natural climate variability, over the last few millennia, are critically needed to better understand future climate change.
Pauline is also engaged with a number of collaborative projects, e.g. Flinders Ranges, to build longer-term records of climate change during the last deglaciation and the Holocene.
