The Campanian age (Late Cretaceous) is characterized by a warm greenhouse climate with limited land-ice volume. This makes this period an ideal target for studying climate dynamics during greenhouse periods, which are essential for predictions of fut

Isotopic ratios of Saturn's rings and satellites: Implications for the origin of water and Phoebe

Autor: Robert H. Brown, Dale P. Cruikshank, Gregg A. Swayze, Roger N. Clark

Publikováno v: Icarus. 321:791-802

Isotopic ratios have long been used to learn about physical processes acting over a wide range of geological environments, and in constraining the origin and/or evolution of planetary bodies. We report the spectroscopic detection of deuterium in Satu
