> STABLE ISOTOPES AND THE INTEGRATION OF BIOLOGICAL,
> ECOLOGICAL AND GEOCHEMICAL PROCESSES
> AAB Meeting to be held at the University of Newcastle upon Tyne
> 9-11 July 1996, in conjunction with SEB and BES.
> The meeting will provide a theoretical and practical framework to the 
> analysis and interpretation of the stable isotope signals across a range 
> of applications. Latest developments in mass spectrometric analysis and 
> sample preparation for carbon, oxygen, hydrogen and nitrogen will be set 
> against the theory underlying fractionation and implications for primary 
> production of organic material. The transformations associated with the 
> hydrological cycle, soils and vegetation will be compared for a range of 
> ecosystems. Ultimately, the aim is to validate models of resource 
> acquisition and turnover in terrestrial and aquatic ecosystems, producing 
> a sounder basis for palaeoclimatic reconstruction and more reliable 
> predictions for future climate change. 
> Provisional programme:
> Monday 8 July
> 12:00 Excursion to Hadrians Wall and the Whin Sill
> 17:00-18.30 Registration at Castle Leazes Halls of Residence
> Tuesday 9 July

> delegates from Castle Leazes to Curtis Auditorium at 08:30 Tues-Thurs)

> Howard -- Looks just great .  I shall be sorry to miss it : i could 
have learnt a lot.  But BOREAS COMES FIRST!! (Ican't underdtand how 
Jim and Larry can be away during the main IFC!!)
