摘　　要：The microparticle concentration in an ice core from coast area, East Antarctica, has been measured by a Coulter counter and optic counting. It is proposed in the present paper that the microparticle concentrations in different areas are different, especially from the coast to the inland in Antarctica. After its comparison with microparticle concentrations from other cores, it is also proposed that there is a lag between the coldest climate (i. e. 18 ka B. P.) and the highest microparticle concentration.The microparticle concentration in an ice core from coast area, East Antarctica, has been measured by a Coulter counter and optic counting.
