Rethinking deep water sedimentary processes on the Irish margin: a new perspective on North Atlantic circulation

Summary

The Irish continental margin sits within the glacially influenced portion of the NE Atlantic continental margin (Weaver et al. 2000). The interplay of alongslope and downslope sedimentary processes has been long been recognized as key to understanding the shaping of this margin in the long term (e.g. Stoker, 1998; Elliott et al. 2006; Georgiopoulou et al. 2021). While some parts of this margin (both geographically and within the stratigraphic record) show extensive contouritic deposition (e.g. Feni drift), others have been inferred to have been predominantly shaped by downslope processes in the Late Quaternary (Sacchetti et al. 2012; Verweirder et al. 2021).

Bathymetric, sedimentological and sub-bottom data however seem to show a predominance of contouritic deposits along this margin, on both sides of the Rockall Trough and at varied water depths. This region is known to be the pathway for the exchange of water masses in the North Atlantic (New & Smythe-Wright, 2001), but limited data exists to date on their actual distribution and velocity. This project will investigate past and present oceanographic processes as recorded in the current seafloor geomorphology and subseafloor stratigraphy using a combination of high-resolution multibeam bathymetric data, seismic and core data.

This will help to better understand contouritic deposition on this margin and refine the oceanographic models for this region with implications for our understanding of the broader North Atlantic circulation patterns.

Please note:

• A project proposal is not required with this application.
• Part-time mode of study is only applicable to DfE applicants.
• The project is suitable for a self-motivated applicant with Earth Science, Geology, Geography, Environmental Science or Marine Science background, with some experience using seismic data.

Essential criteria

Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.

We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.

In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.

• Experience using research methods or other approaches relevant to the subject domain
• A comprehensive and articulate personal statement
• A demonstrable interest in the research area associated with the studentship

Desirable Criteria

If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.

• First Class Honours (1st) Degree
• Completion of Masters at a level equivalent to commendation or distinction at Ulster
• Research project completion within taught Masters degree or MRES
• Practice-based research experience and/or dissemination
• Experience using research methods or other approaches relevant to the subject domain
• Work experience relevant to the proposed project
• Publications record appropriate to career stage
• Experience of presentation of research findings
• Use of personal initiative as evidenced by record of work above that normally expected at career stage.

Equal Opportunities

The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.

Appointment will be made on merit.

Funding and eligibility

This project is funded by:

• Department for the Economy (DfE)
• Vice Chancellor's Research Scholarship (VCRS)

Our fully funded PhD scholarships will cover tuition fees and provide a maintenance allowance of £19,237 (tbc) per annum for three years* (subject to satisfactory academic performance).  A Research Training Support Grant (RTSG) of £900 per annum is also available.

These scholarships, funded via the Department for the Economy (DfE) and the Vice Chancellor’s Research Scholarships (VCRS), are open to applicants worldwide, regardless of residency or domicile.

Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.

*Part time PhD scholarships may be available, based on 0.5 of the full time rate, and will require a six year registration period (individual project advertisements will note where part time options apply).

Due consideration should be given to financing your studies.
