GOALS
Observe changes in the isotopic composition of oxygen in the air (in a controlled environment) and quantify the isotopic fractionation of oxygen associated with biological processes in order to reconstruct past changes in biosphere productivity from gas samples measured in ice cores.
Past dynamics of continental atmospheric humidity and vegetation: contributions from the triple oxygen isotope composition
