Colleagues--                                                                                    
                                                                                                
We would like to call your attention to Session 17f - Linking geochemical tracers and metabolic pathways - to be held at the upcoming Goldschmidt meeting in Davos.               

We have lined up Valeriy Smirnov (out of Justine Roth's lab at JHU, presently at U Montana) to deliver a keynote on the enzymatic mechanisms behind stable isotope fractionation, and have a slate of invitees onboard to give talks across the metabolic spectrum. Please consider joining us!

If you have any questions about the session, don't hesitate to email us. Note the abstract deadline (February 22nd, 2009 - 23:59 UTC) is fast approaching.                                                                                    

Best wishes,

17f: Linking Geochemical Tracers and Metabolic Pathways
Convenors: Boswell Wing, Aubrey Zerkle
Keynote: Valeriy Smirnov (University of Montana/Johns Hopkins University)                       

Several important problems in geology cannot be solved without including a geomicrobiological component (e.g. deep storage sites of CO2 or nuclear                         
wastes, oceanic crust hydrothermalism, low temperature serpentinization and hydrogen generation, sediments, generation of gas hydrates, anaerobic                       
oxidation of methane, acid mine drainages, interpretation of ancient mineralization, etc). Approaches relying upon molecular biology are being                       
developed and it is important to bridge their results with those of geochemical studies (e.g. stable isotopes) which allow for mass balance                         
and fluxes determination. The purpose of this session is to gather studies coupling stable isotopes or other tracers with major metabolic pathways.                        
The session will include studies showing laboratory calibrations of geochemical signatures induced by various microorganisms and                                    
biogeochemical interpretation of geochemical signatures due to specific microorganisms.
