Abstract Investigation of centimeter-scale snow surface chemistry has been carried out at two polar sites with different site characteristics-in Dronning Maud Land, Antarctica and on the Greenland ice sheet, respectively. Large variations in both impurity content and stable oxygen isotope ratios (delta 18O) were found on the submeter scale. delta 18O and the concentration of nitrate correlated at both sites. At the Antarctic site, delta 18O is also correlated to concentrations of methanesulphonate and sulphate while no such correlation exists at the Greenland site. Instead, a strong anticorrelation between sulphate and methanesulphonate is found among the samples from the Greenland site. (mod. journ. abst.)
