摘要：

During the Mariner 7 flyby of Mars, the infrared spectrometer recorded distinct, sharp absorptions near 3020 and 3300 reciprocal centimeters between 61°S and 80°S. at the edge of the southern polar cap, with maximum optical density near 68°S and 341°E. These hands, which match in frequency the v3 bands of methane and ammonia, can be associated with previously unreported spectral features of solid carbon dioxide exceeding 1 millimeter in thickness. Possible reasons for the geographic localization are discussed.
