Informationen zum Autor Richard Soare is a physical geographer (MSc, Geography; BSc/BArts, Biology-Geography (McGill University); D.Phil., Political Philosophy (Oxford University); MA, Political Science, BA, Honors Philosophy (McGill University). He specializes in the study of periglacial (cold-climate and non-glacial) landscapes and has spent numerous field seasons in the low, medium and high Canadian arctic pursuing this interest. Through the last twenty years his focus has been off-planet, i.e. identifying possible periglacial-environments on Mars and evaluating the extent to which these environments may have been shaped by freeze-thaw cycling in the relatively recent past. His work spans Mars geographically, ranging from Utopia Planitia in the northern hemisphere to the Argyre impact-crater in the southern hemisphere, and has been published widely in high-impact journals such as Icarus and Earth & Planetary Science Letters. He is the principal convenor of the 1st Late Mars Workshop (October 2018), to be held in Houston, Texas and was recently a participating scientist on a Synthetic Aperture Radar instrument concept-study funded by the Canadian Space Agency. Klappentext Dynamic Mars: Recent and Current Landscape Evolution of the Red Planet presents the latest observations, interpretations, and explanations of geological change at the surface or near-surface of this terrestrial body. These changes raise questions about a decades-old paradigm, formed largely in the aftermath of very coarse Mariner-mission imagery in the 1960s, suggesting that much of the interesting geological activity on Mars occurred deep in its past, eons ago. The book includes discussions of (1) Mars' ever-changing atmosphere and the impact of this on the planet's surface and near-surface; (2) the possible involvement of water in relatively new, if not contemporary, gully-like flows and slope streaks (i.e. recurring slope lineae); and (3) the identification of a broad suite of agents and processes (i.e. glacial, periglacial, aeolian, meteorological, volcanic, and meteoric) that are actively revising surface and near-surface landscapes, landforms, and features on a local, regional, and hemispheric scale. Highly illustrated and punctuated by data from the most recent Mars missions, Dynamic Mars is a valuable resource for all levels of research in the geological history of Mars, as well as of the three other terrestrial planets.
