Project Description
Mud volcanism – the surface eruption of sediment-water mixtures – is evident across several planetary bodies. On Earth, mud volcanism is typically driven by methane and frequently found near subduction zones. On icy bodies, such as Ceres and Pluto, mud-ice mixtures are thought to be extruded as viscous slurries. On Mars, there is ongoing debate surrounding the prominence of mud volcanism. Recent experimental studies and remote sensing observations have suggested that mud volcanism might be widespread across the Martian surface; this leads to questions surrounding the availability of sub-surface water, the survival of surface water under the low Martian atmospheric pressure, and support for life. To test these emerging models of Martian mud volcanism an improved understanding of mud rheology is required – i.e., an understanding of how the mud flows under a range of conditions. During this studentship you will perform rotational and extensional rheometry experiments to quantify how variable mud-water mixtures flow under shear and extension. These experimental results will be used to (i) assess the likelihood that what are currently interpreted to be Martian volcanic landforms are in fact formed by mud volcanism and (ii) update models for mud flow advance.
The opportunity, support, and training
You will join a multi-disciplinary team within the Lancaster Environment Centre, one of the largest groupings focused on environment-orientated research in Europe. You will also be part of Dr Jones’ Geophysical Fluid Dynamics (GFD) research laboratory and the wider volcanology research group featuring multiple academic staff, post-docs, PhD and MSc students. The GFD lab is a new (2022) multi-million-pound research facility generously funded by UKRI, NERC and the Royal Society. You will be trained in aspects of physical volcanology, planetary science, and fluid dynamics. You will learn how to use specialist rheometry equipment and how to perform laboratory experiments scaled to the environments on other planetary bodies. You will develop your GIS mapping and computer-based skills by mapping and modelling mud flows on the Martian surface. You will enhance your scientific writing and presentation skills by having the opportunity to attend national and international conferences. Depending on your strengths and interests there could be the opportunity to perform overseas fieldwork.
General eligibility criteria
Enthusiasm, independence, self-motivation, curiosity, and the ability to communicate to a range of audiences are all distinctly advantageous qualities for a PhD. Applicants would normally be expected to hold a minimum of a UK Honours degree or equivalent at 2:1 level or above in a relevant subject area. However, applicants who have gained experience in relevant fields through non-traditional routes are strongly encouraged to apply. We particularly welcome applications from Black, Asian, or Minority Ethnic (BAME) candidates, candidates who are in the first generation of their family to go to university, candidates who have been in care or who have been a young carer, mature students, and candidates from a low-income background.
Project specific criteria
We are looking for an enthusiastic and determined student who wishes to work with us on this timely project. The project would suit candidates from many backgrounds such as physics, geology, environmental science, geography, and engineering or be able to demonstrate the required skills. No prior knowledge of planetary science is required provided that the candidate has an interest and shows desire to learn. The candidate will be supported by experienced supervisors with backgrounds in planetary science and laboratory experimentation and will receive appropriate training.
Studentship funding
Full studentships (UK tuition fees and stipend (£17,668 2022/23 [tax free])) for UK students for 3.5 years. No additional funding is available for international students. The stipend amount for 2023/24 will be announced in Spring 2023.
