Project Description

A full project description can be found on Find a PhD. Please see below for additional information about this project:

It is expected that suitable study sites will be identified at the outset of the project, and that most fieldwork will be completed within the first year of study. All necessary facilities are available at QUB or UAber.

Essential skills

  • Masters degree in palaeoenvironmental or related discipline; experience of laboratory work; experience of microscopy

Desired skills

  • Experience in any of the methods to be applied in this study

Impact

Peatlands are a globally important store of carbon, and are under considerable threats from both land-use and climate change. Records of past carbon accumulation inform our understanding of peatland’s ability to sequester carbon under differing climate regimes. This study will focus on a period in which peatlands were exposed to a warmer/drier climate, and will investigate peatland responses to those changing conditions. Firstly, it will control for human impact (deforestation) as a driving mechanism for the observed changes. Secondly, it will establish the nature and timing of climate change using multiple proxies from the peat and subfossil bog wood. Thirdly, it will consider carbon accumulation, and how this responded to changing climate, including the effects of oak and pine expansion onto bogs. The study will include a range of bogs in Northern Ireland and Scotland, encompassing a region that shares a common climate regime, in order to test replicability of results or identify site-specific factors influencing peatland responses to climate change. The study will contribute to a stronger understanding of peatland processes and their role in carbon capture, and to improving dynamic simulation models of soil organic matter turnover in present day peats.

Proposed Supervision

The project will be supervised primarily by Dr Gill Plunkett (QUB) whose expertise lies in peatland palaeoenvironmental reconstructions and palynological investigations of past land-use and vegetation history. Co-supervision will be provided by Jo Smith (UAber), who specialises in soil organic matter modelling, and Prof. Graeme Swindles (QUB) who will advise on testate amoebae and C analysis, and their interpretation.
