Soluble Particulates in Ice from Site 2, Greenland.
Abstract
Collections of soluble and insoluble particles made by sublimation techniques from small pieces of polar ice are well suited for microscopic and microchemical analysis. Examination of an 89-cm vertical profile of a polar ice core from a depth of 100m at Site 2, Greenland, indicated no seasonal cycle in the abundance of particles >2 micrometer in diameter. Microchemical spot tests made on individual particles indicated the presence of NH+, K+, Ca2+, Na+ and Cl-. Whole filter spot tests for K+ indicated no systematic variation in the concentration of potassium-bearing particles. The concentrations of Na+, K+, Ca2+ and Mg2+ were measured in melted fractions of the same core profile by atomic absorption spectrophotometry. Variation of the K+ concentration and variation of the number of potassium-bearing particles per gram of ice have a correlation coefficient of 0.93 over the 21/2 years of accumulation studied.
