The Chemistry of 700 Years of Precipitation at DYE-3, Greenland.
Concentrations of sodium, potassium, magnesium, calcium, silicon, aluminum, lead and sulfate were measured in surface snow and in individual annual accumulation layers from a 373-m-deep ice core from Dye 3, Greenland (65 deg 12 min N, 43 deg 47 min W), covering the time period from 1232 to 1971 A.D....
