Text Description: From south Greenland Dye 3 core. Ice samples of 2.5 cm along the core were taken over the depth range 736.325 to 736.800 m; substantial number of microtephra particles in the size range of 1 to 5 microns, with very few particles up to 10 microns. The total concentration of microparticles, some 0.1 mg/kg of ice, is much too small to give rise to a visible layer in the ice.
