Research interests

Key Research Topics: 1) Stable isotopes in the understanding of a) greenhouse gases b) past climate change c) mantle-derived mineralization; 2) Greenhouse gas sources, sampling, instrumentation and measurement. Mobile measurement and characterisation of methane emission sources.

Since setting up the atmospheric laboratory and isotopic extraction lines at RHUL in 1994 I have become heavily involved in the use of carbon isotopes as tracers of environmental change. This has mostly involved the study of methane from understanding the seasonal to long term changes in global background, to investigating and understanding local sources, and more recently studying the potential of isotopic tracers as a validation tool for greenhouse gas reductions and inventory verification. One focus has been on the automation and reduction of sample sizes required for high-precision stable isotope analysis of greenhouse gases, including its application to diurnal cycles of greenhouse gases in urban areas.

Currently research project involvement includes NERC funding for the MOYA and ZWAMPS projects, studying tropical wetland and burning methane sources, and the Equipt4Risk and DARE-UK projects foxussing on UK methane emissions and distribution. I am isotope WP2 leader on the Marie Curie Integrated Training Network (ITN) Methane goes mobile: measurement and Modelling (MEMO2),, a member of the BEIS-funded baseline consortium, co-ordinator of the UN CCAC southern North Sea fugitive emission project and partner on other UN oil and gas fugitive emissions projects  Main interests in these projects iare the use of laser spectroscopy for the measurement of carbon gases in the atmosphere, particularly mobile measurement of methane emission plumes, and plume sampling for further lanalysis in our greenhouse gas laboratory, particularly carbon and hydrogen isotopes of methane.

Geological-focussed NERC projects in the 1992-1998 period included the application of stable isotopes to mantle or mantle-derived mineralization, mostly oxygen isotope work on diamond inclusions, mantle nodules, and chromites in ophiolites and layered intrusions, mostly in southern Africa, Greenland and Scotland (Rum, Shetland). Data are used to understand sources of oxygen, the heterogeneities of the mantle and temperatures of formation. More recent geological research has focussed on the use of the stable isotopes of S (pyrite) and C (carbonates, black shales) to better understand the Dalradian Supergroup of Scotland and Ireland, particularly the extreme Neoproterozoic climate fluctuations from greenhouse to icehouse between 720 and 580 Ma.
