The motivation for this development is the capture of the isotopic composition of soil respired CO2 , which is sensitive to concentration gradients that are inherent to conventional chamber systems.
His work at SEI York concentrated on the fate of ozone in a plant-soil system. It involves a novel experimental approach, in which plant-soil systems are fumigated with isotopically labelled ozone (18O).
The aim is to trace the flux of this pollutant to individual components within the plant and the soil. This work is done in close cooperation with groups at the universities of Newcastle, Bradford and Bristol.
