Background

Dr. Geoff Abbott has more than three decades of research experience in organic geochemistry. He is a member of the Geoscience group which is now incorporated into the School of Civil Engineering and Geosciences. His research focuses on the carbon cycle in peat, soils, ancient sediments and waters. This work therefore has a potential impact on mitigating climate change. His teaching focuses on biomarkers, kinetics and analytical geochemical methods.

Memberships

European Association of Organic Geochemists (EAOG);
Founding member of British Organic Geochemical Society (BOGS).

  

Research Interests

Dr. Geoff Abbott's research interests and expertise currently encompass the following areas: (i) the fundamental processes controlling carbon cycling in peat, soil, litter, and waters within peatland, forest, moorland and grassland ecosystems; (ii) the structure and function of asphaltenes where the recent application of acoustic spectroscopy has been particularly exciting; (iii) the identification, fates and the reaction kinetics of biomarkers in sedimentary rocks, kerogens, asphaltenes and coals; and (iv) the molecular characterization of early land plants and the unravelling of past climate and environmental change during phytoterrestrialisation (Ordovician-Silurian-Devonian).

Funding

Current funding includes:
1) Geochemical control of organic matter turnover in peatlands: Long-term security or short-term vulnerability of a major carbon store?
Dr Geoff Abbott (with Belyea (Queen Mary) and Cowie (Edinburgh)
NERC NE/E004709/1
2008-2011, £566,834
Peatlands cover vast areas of the world - around 4 million square kilometres - and store about as much carbon as do the living plants in tropical rainforests. For the past 5,000-10,000 years, the plants living on peatlands have been fixing carbon dioxide from the atmosphere and storing it as dead plant matter - "peat". In a future warmer, and possibly drier, climate, this stored carbon could be respired back to the atmosphere or leached into rivers. Will increased temperatures and decreased rainfall lead to rapid loss of the peatland carbon store? If so, then the extra carbon released from peatlands could enhance "greenhouse" warming further, leading to a runaway positive feedback on global climate. Or will rapid climate change trigger a shift to peatland types that accumulate peat (and store carbon) at a faster rate than present-day peatlands? If the latter, then peatlands could buffer further climate change.
