The Klotz Abakus laser sensor and the Coulter counter are both used for measuring the size distribution of insoluble mineral dust particles in ice cores. While the Coul- ter counter measures particle volume accurately, the equivalent Abakus instrument measurement deviates substantially from the Coul...
