 Post Doctoral Research Fellow - Evolution of Marine Ecosystems: Nd Isotope Records of Ocean Circulat

Closing Date25/02/2011
LocationWaterfront

Salary - £27,319 – £29,853 per annum 


School of Ocean and Earth Science 

This vacancy is part of a research grant awarded to the Universities of Southampton, Plymouth and Oxford entitled ‘The Evolution of Modern Marine Ecosystems’. It forms part of the NERC directed programme on Long-term Co-evolution of Life and the Planet (http://www.nerc.ac.uk/research/programmes/lifeplanet/). 


The project is a multi-disciplinary investigation into the effects of long and short term environmental fluctuation on the early evolution and ecological organisation of modern marine ecosystems. In particular, the project focuses on four global biotic crises ranging in time from the Permian/Triassic to the Cenomanian/Turonian events. High resolution records of community composition and ecological structure will be developed by the palaeontological team, and contemporary geochemical records of temperature, oxygenation and circulation will be produced by the geochemical team. The project has a large fieldwork component encompassing work in Europe, the USA, Spitzbergen and Canada, and the Southampton postdoc will be expected to participate in field work depending on experience. 

The Southampton component of the project concentrates on using Nd isotope composition of vertebrate material (e.g. fish teeth) to recover records of ocean circulation.  A major focus of this project will be using new ytical screening techniques based on the Lu-Hf isotope system to test whether (and under which conditions) the Nd isotope composition in ancient teeth preserves an intact bottom water signal. The project thus has wide implications for the use of bioapatite remains as a host for palaeoceanography proxies. The work will involve using state-of-the-art ytical techniques and equipment housed at the University of Southampton (Neptune MC-ICPMS and Element 2 ICPMS).  

The applicant will have a PhD in isotope geochemistry or palaeoceanography with experience in radiogenic isotope chemistry (e.g. Sr or Nd isotope ysis). They should also have a good knowledge of biominerals and biomineral diagenesis. An appreciation of Mesozoic climate and/or marine palaeoecology would be an advantage. In all cases, the applicant will demonstrate the ability to conduct innovative research leading to high-impact publications in international refereed journals.  Experience of isotope ysis by MC-ICPMS and clean laboratory practise is also desirable.  


The post is fixed term for 3 years commencing April 2011. 

Informal enquiries only (please do not send CV’s) can be made to Dr Clive Trueman on 023 8059 6571, email – trueman@noc.soton.ac.uk
