The authors report on methanesulfonate and non-seasalt sulfate found in an artic ice core from Greenland. The ice core record stretches back in time roughly 130,000 years, through a full glacial cycle. This record reveals a decreasing concentration of MSA with the advance of the glacial period, and a drop in temperatures, while the non-seasalt sulfate increased in concentration. The MSA data is in contrast to similar measurements from the southern hemisphere. The ratio of MSA to non-seasalt sulfate is found to have a strong linear relationship to the temperature, higher ratios being associated with warmer climatic periods.
