BiographyI am a professor in Chemical Oceanography. I completed a B.Sc in biological chemistry at the University of Essex, a MSc in Forensic Science at Strathclyde University and a PhD at Leeds University. My PhD thesis was entitled “Diagenesis in deep sea sediments with special reference to iodine”. After a postdoctoral position at the Bullard Laboratoies, University of Cambridge, I took up my current position here at Bangor.
My research interests are focussed on the use of stable isotopes (carbon, nitrogen, oxygen and sulphur) in tracing biogeochemical process and in validating the use of tracers for palaeoenvironmental reconstruction. In the seagrass meadows of Asia and Europe stable isotopes are being applied to trace both the source of organic matter to the sediments and to the local food web; to validate their use as indicators of changes in nutrient loading to the coastal environment and to determine the impact of anoxic conditions on the health of seagrass meadows. I am also interested in the importance of
seagrass meadows as coastal carbon sinks.
In Antarctica, the spatiotemporal variations in stable isotope composition (13C and 15N) of sea ice algae and open water plankton are being used to examine how the extreme environment of Antarctica can affect the biogeochemical pathways for carbon and nitrogen. In more local studies I have been involved in calibration (experimental and field) studies of marine molluscs to determine their utility and validity in palaeo-reconstruction. This is being expanded to include the study of foraminifers, especially in polar waters. I also have a more general interest in sediment diagenesis and use both the elemental and isotopic records in sedimentary pore waters to determine benthic remineralisation and fluxes.
