About the research project

Current predictions of future sea-level rise are very uncertain because the processes governing Antarctic Ice Sheet change in a warming climate are poorly constrained. It is not known how quickly, and where, the ice sheet will melt in the future. East Antarctica holds the largest proportion of continental ice in low-lying basins hundreds to thousands of meters below sea level, making these sectors susceptible to warming ocean temperatures. Past climate records from marine sediment cores can provide data on past ice sheet behaviour during previous warm climate states that can help lower model-based uncertainties on future sea-level rise.

This project will focus on tracking the geochemical signature of meltwater input and dissolved solute load released from the ice sheet in both the current climate state and in the past. The research will apply both elemental and isotopic methods in chemical oceanography and paleoceanography. The modern observations will inform marine sediment-based approaches, including understanding sediment-porewater interactions to assess geochemical proxies for recording episodes of past glacial meltwater release during warm climate periods. The project will be based on new samples collected on an upcoming field campaign to Antarctica. To participate in fieldwork in January 2023 please contact Taryn Noble as soon as possible to commence your PhD application.
