Ice core records provide us a way to investigate past climate and look in detail at past atmospheric conditions. With, on average, higher CO2 concentrations in the Greenland record, the focus of this project was on the potential mechanisms responsible for the higher CO2 concentrations in the Greenland ice core record. Contamination in the ice is believed to be due to oxidation and dissolution processes, however, our results show no significant connection between the chemical processes in the ice and the higher CO2 concentrations.
