PhD Position in Deciphering Submarine Slope Processes
in the Ross Sea, Antarctica

Project description

The need to substantially improve knowledge about the future behaviour of the West Antarctic Ice Sheet (WAIS) has taken on a new urgency with rates of ice loss doubling in recent years around Antarctica (McMillan et al., 2014). Determining the signature of past slope processes (e.g. debris flows, turbidity currents, down-slope currents, along-slope currents, mass wasting) (e.g. Gales et al., 2014) provides huge potential for understanding how ocean and climate circulation changed in the past and may provide important clues as to how they may change in the near future; and what effects this may have on ice retreat and sea-level rise.

This project will examine an exceptional multidisciplinary dataset including geomorphological, geophysical, geological and oceanographic evidence of past and present slope processes on the Eastern Ross Sea continental slope. Data includes new multibeam swath bathymetry, sub-bottom profiles, seismic data and oceanographic data collected in 2017 and sediment cores collected during the International Ocean Discovery Program (IODP) Expedition 374 in 2018.

The signature of past slope processes are visible in newly collected seismic data along the shelf edge of the Ross Sea margin. This includes buried palaeo-gullies and channels at the shelf edge. This project aims to link these features through seismic-sediment core integration to understand when gullies and channels were active, the processes influencing their formation, and the triggering mechanisms behind the processes. The project will include grain size analysis using a laser particle size analyzer, sediment core and geotechnical analysis and integration with oceanographic and geophysical datasets. This will provide key insights into past ocean circulation, ice-sheet dynamics and climate change, critical for future ice-sheet and sea-level predictions.

Funding and How To Apply

The studentship will have a three year duration and will cover full-time Home/EU tuition fees plus a stipend of 14,777 per annum. The studentship will only fund those applicants who are eligible for Home/EU fees with relevant qualifications. Applicants required to cover overseas fees will have to cover the difference between Home/EU and overseas tuition fee rates (approximately 10,350 per annum).
