Radio echo-sounding of the Antarctic ice sheet.
Journal of the Japanese Society of Snow and Ice, 1989 氷床流動の観測に基づいて, 南極氷床の変動 (例えば, 氷床域の拡大, 縮小) を明らかにすることを目的として, 東南極の東経35度から東経45度に至るみずほ高原地域において, 過去20年にわたって観測が続けられてきた.その結果, 白瀬氷河流域では.年間約70cmもの氷厚の減少が観測された.この氷厚減少から, 白瀬氷河流域の氷床が不安定状態にあることが示唆され, 原因として, 氷床底面での“底面すぺり”が指摘された。そこで, 氷床底面の物理的状態を調べるために電波氷厚計を用いての電波探査が氷床上の流動測定・雪氷観測ルートに沿って, 1982年以降実施された.これまでの電波観測では, 送信時刻と基盤からの反射時刻の時間間隔から氷厚のみを求めていたが, この研究では, 氷床氷の厚さを測定するだけでなく,

Preliminary studies of electromagnetic sounding of cometary nuclei [PDF]
The internal structure of a comet could be determined with a spacecraft borne electromagnetic sounder. A dielectric profile of the comet could be produced in direct analogy with terrestrial glacier and ice sheet sounding experiments.
