About the Partnership

This project is one of a number that are in competition for funding from the NERC Great Western Four+ Doctoral Training Partnership (GW4+ DTP).  The GW4+ DTP consists of the Great Western Four alliance of the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five Research Organisation partners:  British Antarctic Survey, British Geological Survey, Centre for Ecology and Hydrology,  the Natural History Museum and Plymouth Marine Laboratory.  The partnership aims to provide a broad training in earth and environmental sciences, designed to train tomorrow’s leaders in earth and environmental science.

For eligible successful applicants, the studentships comprises:

  • An stipend for 3.5 years (currently £17,668 p.a. for 2022-23) in line with UK Research and Innovation rates
  • Payment of university tuition fees;
  • A research budget of £11,000 for an international conference, lab, field and research expenses;
  • A training budget of £3,250 for specialist training courses and expenses

Project Background

Volcanic ash and gas clouds pose significant hazards to human life, infrastructure, and aircraft. Understanding the relationship between the height of a volcanic plume, the intensity of an eruption (i.e. its mass flux) and atmospheric conditions at the volcano is key to managing eruptive crises, reconstructing past eruption dynamics, and preparing for future eruptions. Eruption intensity estimates vary by orders of magnitude depending on measurement method. These uncertainties undermine volcanic hazard management. Furthermore, it is currently unknown how climate change could affect the life cycle and dispersion of volcanic ash and subsequent hazards.

Project Aims and Methods

You will be encouraged to design your own project in the broad area of the rise and dispersion of volcanic plumes, based on your own ideas and preferences.

Our vision is that you will take advantage of novel datasets and state-of-the-art models to conduct a systematic comparison of eruption intensity estimates derived from: i) empirical field relationships; ii) ash dispersion models; and iii) satellite observations of volcanic clouds. You will get familiar with these methods for a case study eruption for which you will collect data on the ash deposit during field work, before extending your work to all eruptions for which required data are available in the literature. Your project will contribute to IVESPA (http://ivespa.co.uk/), a database of eruption source parameters endorsed by the international volcanology community in which intensity currently only rely on field-derived estimates. Ultimately, you will help stakeholders such as the BGS or the UK Met Office to improve advisories delivered to authorities during eruptive crises. In a forward-looking phase, you could apply your new skills in ash dispersion modelling to understand how climate change could modulate volcanic hazards at volcanoes in Guatemala, Italy, and Iceland. 

Candidate requirements

Applicants should hold a degree in Earth Sciences, physics, mathematics, or related fields. Strong skills and prior experience with scientific programming (e.g. Python, Fortran, Matlab) are preferred. Specialist knowledge in volcanology or atmospheric sciences would be a bonus but is not required.

Project partners 

You will work hand-in-hand with your interdisciplinary supervisory team and their international partners in volcanology, climate sciences and governmental agencies. We anticipate that you will spend 2-3 months in Barcelona at GEO3BCN with Arnau Folch, 1 month in Edinburgh at BGS with Samantha Engwell, and 3 weeks doing fieldwork abroad (potential locations: Guatemala or Indonesia). In addition to the £14,250 provided by the DTP for research and training activities, you will have access to high performance computing resources from GEO3BCN and we are applying for an additional budget of £8,000 from the BGS to support your research activities and placements.

Training

You will get training in scientific programming and modelling, one of the most marketable skills for both academic and non-academic employers, at the University of Exeter and GEO3BCN. You will gain experience in volcanology, including through fieldwork abroad, and training in volcanic deposit analyzing at the BGS in Edinburgh. You will improve your communications skills by presenting your results at least two international conferences and one UK conference as well as in scientific papers.

Eligibility

NERC GW4+ DTP studentships are open to UK and Irish nationals who, if successful in their applications, will receive a full studentship including payment of university tuition fees at the home fees rate.

A limited number of full studentships are also available to international students which are defined as EU (excluding Irish nationals), EEA, Swiss and all other non-UK nationals.  For further details please see the NERC GW4+ website.

Those not meeting the nationality and residency requirements to be treated as a ‘home’ student may apply for a limited number of full studentships for international students. Although international students are usually charged a higher tuition fee rate than ‘home’ students, those international students offered a NERC GW4+ Doctoral Training Partnership full studentship starting in 2023 will only be charged the ‘home’ tuition fee rate (which will be covered by the studentship). 

International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD. More information on this is available from the universities you are applying to (contact details are provided in the project description that you are interested in.

The conditions for eligibility of home fees status are complex and you will need to seek advice if you have moved to or from the UK (or Republic of Ireland) within the past 3 years or have applied for settled status under the EU Settlement Scheme.
