Record #35370:

Polar ionospheric spread echoes and radio frequency properties of ice shelves / Stanley Evans.

Title: Polar ionospheric spread echoes and radio frequency properties of ice shelves / Stanley Evans.
Author(s): Evans, Stanley.
Date: 1961.
In: Journal of Geophysical Research. (1961.), Vol. 66(12) (1961)
Abstract: Based on records obtained in Antarctic and Arctic. Downward radiation from ionosonde aerial is reflected from sea water under ice shelf. As ice is several wavelengths thick, interference pattern is established which makes it possible to derive thickness and dielectric constant of ice, and direction from which ionospheric spread echoes arise.
Notes:
