摘要

We have measured the in situ average electric field attenuation length, (La), for radio-frequency signals broadcast vertically through the Ross Ice Shelf, Antarctica. We chose a location, Moore Embayment, south of Minna Bluff, known for its high reflectivity at the ice-sea interface. We confirmed specular reflection and used the return pulses to measure the average attenuation length from 75-1250 MHz over the round-trip distance of 1155 m. We find to vary from 500 m at 75MHz to 300 m at 1250MHz, with an experimental uncertainty of 55-15 m.
