  • 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 details

Project Background:

Phytoplankton are fundamental to all marine ecosystems and those that depend on them. They sustain oceanic biogeochemical cycles and help to regulate our climate, yet are under enormous threat and change from warming, ocean acidification, eutrophication, extreme weather events and pollution. Understanding the factors influencing the seasonal structure of phytoplankton communities and how this is influenced by environmental change is the key challenge of this PhD.  

Project Aims and Methods:

Within this PhD, you will determine the seasonal signature of key taxa, identify drivers of variability, and  predict the impact of a changing climate on phytoplankton communities. This will be achieved using both morphological (i.e. microscope) and molecular datasets as a means of taxonomic identification, and you will have the opportunity to learn both techniques. You will make use of extensive morphological (30+ year) and molecular (10 year) data collected at the Western Channel Observatory (WCO -https://www.westernchannelobservatory.org.uk/) site L4, and you will be responsible for continued collection of high-quality molecular data sets. DNA-based approaches have the potential to provide unprecedented detail and insight into the ecological connections between taxa and their environment at a fraction of the sampling cost of traditional methods such as time-consuming microscopy, but there is an urgent need for proof-of-concept studies that provide a thorough comparison of data derived from traditional methods.

Within this PhD, you will have a unique opportunity to explore detailed, matching morphological and molecular data sets to identify gaps and synergies, with the aim of developing best practises. There is increasing interest in the use of eDNA as a tool for marine management through the development of biological Essential Ocean Indicators (EOVs) as markers for ocean health. Your data will be mined to determine which key measurements can be used to assess the health of the WCO. You will also have the opportunity to learn and employ novel single cell sorting techniques to isolate individual species for DNA sequencing in order to create detailed DNA reference libraries for local species.

Candidate requirements:

We seek an enthusiastic, self-motivated candidate, with a broad interest in marine ecology. You will have at least a 2.1 BSc in biology, chemistry, oceanography or a suitable branch of environmental sciences. The ideal candidate will either have expertise and/or knowledge of molecular biology and bioinformatics, or a strong desire to learn these skills. Plymouth Marine Laboratory and Exeter University value a diverse research environment, and we welcome and encourage student applications from under-represented groups.

Project partners:

You will have the opportunity to work within two contrasting world-class research environments: PML and Exeter University’s Living Systems Institute. The majority of your time will be spent at PML where you will be immersed in a unique, independent research centre with a focus on cutting-edge interdisciplinary marine research. You will have access to PML’s recently refurbished molecular biology and microscope facilities and research vessels. At Exeter University, you will have access to the research facilities at the Living Systems Institute where you will learn state-of-the art sequencing, bioinformatics and bioimaging techniques. This project benefits from being closely aligned to the NERC’s National Capability Western Channel Observatory programme.

Training:

The supervisory team are committed to providing you with a comprehensive training experience, imparting you with the skills required for a future in scientific research. At PML you will receive specialist training in molecular biology techniques (DNA extraction, PCR) and, if desired, traditional microscope-based identification of phytoplankton. You will also receive a thorough grounding in the application of multivariate statistics. There are ample opportunities to collect your own samples on board PML’s research vessels if desired. At the Living Systems Institute (Exeter University), you will gain expertise in single cell sorting, nanopore sequencing and bioinformatics. You will also be given training in a wide range of professional skills (writing, communication) and will have the opportunity to present your work at national and international conferences.

Prospective applicants:

For information about the application process please contact the Admissions team via pgrenquiries@exeter.ac.uk. Please note that applications received via other routes including a standard programme application route will not be considered for the studentship funding.

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 2022 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.

Entry requirements

Applicants should have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK.   Applicants with a Lower Second Class degree will be considered if they also have Master’s degree.  Applicants with a minimum of Upper Second Class degree and significant relevant non-academic experience are encouraged to apply.

All applicants would need to meet our English language requirements by the start of the  project http://www.exeter.ac.uk/postgraduate/apply/english/.
