Funded PhD Opportunity Fluctuations in North Atlantic Ocean circulation since the beginning of the last glacial cycle

This opportunity is now closed.

Subject: Geography, Environmental Studies and Archaeology

Summary

Knowledge of past deep-ocean current speeds has the potential to inform our understanding of changes in the climate system on glacial-interglacial timescales as these may be used to help constrain changes in deep-ocean circulation rates and pathway. The Rockall Trough, a deep water basin offshore Ireland and UK, 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 the changes in ocean circulation over time in this part of the Atlantic Ocean.

Previous works on deep-water sedimentation in the region have recognised the presence of thick sediment bodies related to the flow of deep-ocean currents, including the Feni Drift and contouritic deposits on the eastern side of the Rockall Trough (Stoker, 1998). Proxies obtained from deep-water sediment cores, such as the mean size and percentage of sortable silt, can be used to assess the variations in the speed of bottom currents (Mao et al., 2018; Spooner et al., 2018).

This project will utilise a series of sediment cores from the continental slope and deep Rockall Trough, for which a chronostratigraphy is already established, to investigate fluctuations in current vigour using grain size measurements with a focus on the sortable silt fraction.

The project is suitable for a self-motivated applicant with Earth Science, Geology, Geography, Environmental Science or Marine Science background, with capacity to learn new analytical techniques and basic statistical analysis.

Funding

    Vice Chancellors Research Scholarships (VCRS)

    The scholarships will cover tuition fees and a maintenance award of £15,009 per annum for three years (subject to satisfactory academic performance). Applications are invited from UK, European Union and overseas students.

    DFE

    The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £15,009 per annum for three years. EU applicants will only be eligible for the fees component of the studentship (no maintenance award is provided).  For Non EU nationals the candidate must be "settled" in the UK.
