Description
Summary: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.
