Environmental Geochemistry and Compositional Data Analysis
This research brings together world-leading expertise in the areas of geochemistry, geoscience, mathematics to stimulate debate and advances in the field of compositional data analysis.
Digital spatial data are becoming increasingly available for environmental studies through sub-continental scale and regional scale ground-based geochemical surveys and an ongoing global geochemical baseline survey. However, data sets such as geochemical surveys data pose many challenges for exploratory data analysis and any subsequent spatial data analysis. Geochemical data are compositional in nature in that they convey relative information. This has implications for a number of fields which routinely use geochemical data including baseline quality assessment, mineral and energy exploration, agriculture and ecology, medical geology, engineering and environmental management. A paradigm shift in thinking is advocated and alternative approaches presented through this collaborative research which emphasises opportunities for using compositional data analysis.
Research projects in this area engage with a multidisciplinary team from geography, geoscience, mathematics, statistics, engineering and health.

This research has brought together world-leading expertise in the areas of mathematical geoscience, geoscience, geochemistry and compositional data analysis to advance the field of compositional data analysis research and stimulate debate to acknowledge and deal with the inherently multivariate nature of compositional data including soil and water geochemistry. The research has encouraged a paradigm shift in the use of geochemical data in the fields of mineral and energy exploration, agriculture and ecology, resilient communities, medical geology, subsurface modelling, engineering and environmental management.
