Currently there is an array of persistent organic pollutants that undergo long-range transport in air and seawater and are present in the Earth’s Polar Regions. These chemicals, arising from industrial, agricultural and domestic sources are present in surface media (seawater, snow) often at trace level, but are undergoing bioaccumulation/biomagnification in the Arctic marine foodweb.

The role of the cryosphere in accumulating and subsequently releasing these chemicals is not understood and yet sea-ice may have a profound influence on pollutant behaviour, serving to accumulate, enrich and finally release chemicals to surface seawater, possibly at times of the year when biological activity is high.

This PhD research project aims to characterise the presence and behaviour of perfluoroalkyl substances and current-use flame retardants in sea-ice and the ice-rafted snowpack, and explore enrichment processes during ice ageing. There is growing concern about the presence of these two groups of chemicals in the wider environment and their wide range of physical-chemical properties make them useful candidates for process-based studies. The goal of the project is to fully resolve contaminant processes in ice by developing a snow-ice model to simulate chemical fate. This is particularly relevant in a ‘warmer’ Arctic with changing ice conditions.

The project will entail ship-based fieldwork in the Arctic and provide excellent opportunities to work with international partner scientists with access to world-leading analytical laboratories.
