Abstract
The purpose of this research was to investigate the statistical relationship between an oxygen isotope chronology from southern Greenland and climatic variables recorded at a coastal village. The response of the oxygen isotope time series to monthly temperature and precipitation data was calculated using a combination of principal components factor analysis and multiple regression analysis. Orthogonal eigenvectors extracted from 35 yr of climatic data reliably explained 59% of the temporal variance in mean annual oxygen isotope values. The response functions demonstrate an apparent seasonal reversal in the relationship between oxygen isotope values and temperature, with the response varying between a positive (direct) relationship in winter, spring, and autumn, and a negative (indirect) relationship in summer. The results, and their implications, are shown to be useful in the historical climatic reconstruction of the South Greenland region.

Although the data are unpublished, the Geophysical Isotope Laboratory of the University of Copenhagen graciously provided not only mean annual δ18O values for the South Dome core, but also made available the entire chronology of individual δ18O measurements and corresponding plotted δ18O profile.
Throughout this study, statistical significance was determined at the 0.95 confidence level.
