USING A MOBILE RADIO ECHO SOUNDER TO MEASURE BEDROCK TOPOGRAPHY IN EAST QUEEN MAUD LAND, ANTARCTICA

概要
- 論文の詳細を見る
As part of the Dome-Fuji Project, the topography of the bedrock over a wide area around Dome-F and along routes from Dome-F to S16 (about 1000 km distance) was surveyed by radio echo sounder with a continuous recording system. The bedrock topography was successfully measured under ice sheets thicker than 3500m, and the performance of the radio echo sounder was confirmed. The highest point of Dome-F was located in the basin like topography of the bedrock, surrounded by more elevated areas. The strength of the bedrock echo were found to differ substantially between inside and outside of the Dome-F area. This difference is probably due to the difference of ice sheet temperatures between these areas, because the attenuation coefficients depend on the ice temperature. The stronger echo at high altitude will enable us to measure ice thickness more than 3500 m.
