Funded PhD Project (European/UK Students Only)
This is an innovative modelling proposal designed to investigate the role of wind waves on the evolution of northwest European shelf seas sediment dynamics since the Last Glacial Maximum (21,000 years before present), when global sea level was ~130 m lower than it is today. Throughout much of the present-day Irish Sea, sediment transport is dominated by tidal currents; however, wave-induced sediment transport can dominate in shallower waters. Through consideration of wave- and tidal-induced sediment transport, it will be possible to compare how their relative influence on sediment dynamics has changed over time. This project focuses on developing a comprehensive coupled wave-tide-sediment model for the northwest European shelf seas (for palaeo-time slices, last 21,000 years). Outputs from the model will be validated against observed evolution of seabed sediment grainsize from age-constrained marine sediment cores. Such a well-constrained model would be a powerful tool, including for predicting significant changes in hydrographic and habitat patters with time; for reconstructing patterns of accumulation of sediments (for marine aggregate extraction); for assisting archaeology and conservation; and for further refinement of observations of sea-levels.
You will be trained in a wide range of research techniques, including ocean modelling on supercomputers, as well as having an opportunity to conduct laboratory work. You shall make use of existing large scale model outputs of winds, tides and palaeobathymetries as input to your regional model. This PhD project is well funded, and includes costs for you to attend several international conferences to present and discuss your research with world-class scientists. By the end of this PhD, you will have developed into an excellent independent researcher with a deep understanding of the evolution of shelf sea environments and equipped with excellent research skills suitable to either further pursue a career in palaeo-environmental studies, or to move onto other exciting challenges in the marine environment.
Throughout the project the appointee will be given the opportunity to meet with diverse groups within the scientific community, and to travel to international conferences to disseminate results and progress the project. Applicants should hold a minimum of a UK Honours Degree at 2:1 level or equivalent in subjects such as Oceanography, Coastal Marine Science, Civil Engineering, Quantitative Methods/Statistics, or Environmental Science. Applicants who additionally have a Master’s degree, or relevant work experience, will be particularly competitive.
