Sensors and platforms, the gamma ray wavelengths to the very high frequencies (VHF) have been employed for remote sensing studies of ice and snow (Fig. 1.1). Although all objects emit radiation over all wavelengths, for most studies it is advantageous to use data from sensors operating in discrete portions of the electro

Permafrost,at least 2 years. It underlies 20 to 25% of the land surface of the Earth and is also found off-shore in many polar areas (Fig. 6.1). In the northern hemisphere permafrost covers an estimated 2.3 . 10. km. in area (Fujii and Higuchi, 1978). The occurrence of permafrost is either continuous, or disco

Emphasis is placed on the use of remote sensing for developing an improved understanding of the physical properties o

Lake and river ice,ome lakes freeze completely to their beds and are not suitable for a fish population whereas other lakes do not, allowing fish to survive below ice during the winter. In addition, ice that forms unexpectedly in lakes and rivers in a particular year can kill existing fish populations.
