抄録
Identification of cosmic dust in Antarctic ice by magnetic methods is discussed based on the rock magnetic results of the clean-ice and dirt-ice. The cosmic dust sized several μm (in diameter) with the saturation isothermal remanent magnetization is identified by the superconducting quantum interference device (SQUID) magnetometer. The direction of natural remanent magnetization of the cosmic dust in ice is discussed. The cosmic dust may be preferably transported to Antarctica through the stratosphere atmospheric circulation. The cosmic dust may be concentrated under the ice surface of bare ice around Antarctic coasts by the interaction of precipitation of cosmic dust in melted water and ablation of ice by the solar radiation. The concentration may not occur in the high land in Antarctica due to too low temperature.
