SUMMARY:The evolution of the geobiological nitrogen cycle - Eva Stüeken\,
  University of St Andrews

CONTACT:David Wallis
DESCRIPTION:Nitrogen limits biological productivity in large parts of the 
 modern ocean\, and it may have constrained the proliferation of life over 
 Earth's history. This talk will discuss how nitrogen isotopes can be used 
 to reconstruct the evolution of nitrogen availability through time. Furthe
 rmore\, hydrothermal vents and lightning will be discussed as potentially 
 important nutrient sources that may have helped sustain the early biospher
 e.
