Topography of the polar layered deposits of Mars
Synthesis of polar topographic data derived from the Mariner 9 radio occultation, ultraviolet spectrometer, and television imaging experiments provides new information on the behavior of polar volatiles and the topographic configuration of the Martian polar layered deposits. Gentle slopes in the vic...
