抄録

A laser-light scattering method was evaluated from the viewpoint of the measurement ability of concentration and size distribution of microparticles in molten ice core samples. It was demonstrated that analysis can be performed with 10 % accuracy by diluting the sample with ultrapure water by 50 times to eliminate coincidence loss. Using this method, the concentration and size distribution of microparticles were determined on 2829 samples from a 2503 m deep ice core drilled at Dome Fuji, Antarctica. The present paper shows the profiles of number and volume concentrations through the whole depth and the changes in the size distribution through three glacial cycles in the past 320 k-years.
