Dynamic Mars: Recent Landscape Evolution of the Red Planet presents the latest developments in understanding the geological history of Mars. Presenting observational data and tightly-linked scientific hypotheses across a broad swath of landscapes, latitudes and geological contexts, as well as an examination of the impact of climate change mitigated by multiple geomorphological agents, the book covers a diverse array of themes and subjects. This highly illustrated book includes data from recent missions, and will be of interest to all levels of research in the geological history of Mars, as well as other terrestrial planets.
For years after the first detailed orbital and ground images of Mars were taken, it was thought that the red planet could have been wetter and warmer in its deep past than today. However, as the book demonstrates, the possible involvement of water in recent, if not contemporary, gully-like flows and slope streaks (i.e. recurring slope lineae), as well as the identification of a suite of geomorphological agents (i.e. glacial, periglacial, aeolian, meteorological, volcanic and meteoric) associated with surface and near-surface changes on a local to regional scale, suggest the history of the red planet may be much more dynamic than previously thought.
- Utilizes observational as well as geological context to examine the geomorphology of Mars and its implications
- Encompasses a broad spectrum of highly-regarded experts and themes contributing to a comprehensive examination of the geological history of Mars
- Includes extensive and detailed imagery to illustrate the topics clearly

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.
Conway, Susan J.
Susan Conway is a CNRS research scientist in Nantes, France, having graduated with a PhD in planetary science from the Open University (United Kingdom) in 2010. She is chair of the International Association for Geomorphologists (IAG) Planetary Geomorphology Working Group, and has run the Planetary Geomorphology session at the European Geoscience Union since 2011. She is lead editor for a collection of papers on Martian gullies and their Earth analogues, based on the workshop she organized at the Geological Society of London in June 2016 and is co-editor on a collection of papers entitled "Frontiers in Geomorphometry". She is a team member on the High Resolution Imaging Science Experiment (HiRISE) instrument on NASA's Mars Reconnaissance Orbiter and Guest Investigator on the ESA Trace Gas Orbiter mission to Mars, specifically focused on the CaSSIS camera and NOMAD/ACS spectrometer instruments. She is on the author list of 35 peer-reviewed papers concerning the geomorphology of Earth, Mars, Mercury, the Moon and the asteroid Vesta. Her work is concentrated around glacial, periglacial and fluvial landforms on Mars, encompassing field, remote sensing and laboratory simulation data, with a specialty in analysis of 3D terrain data.
Clifford, Stephen M.
Stephen Clifford is a Senior Scientist at the Planetary Science Institute in Tucson, Arizona. He received his PhD in Astronomy from the University of Massachusetts in 1984. His research focuses on the nature, evolution and geophysical investigation of planetary volatiles, with a special emphasis on water on Mars. He is the author/co-author of 70 peer-reviewed publications whose topical focus has varied from investigations of H2O transport in cold planetary regoliths; large-scale groundwater transport; low-temperature hydrothermal convection in a sub-permafrost vadose zone; the formation and stability of gas hydrates; glacial flow and polar evolution; thermal modelling of planetary surfaces; the thermal, seismic and hydrologic effects of impact catering; and radar investigations of subsurface geology and the distribution and state of H2O. He was the principal convener of the 1st-4th International Conferences on Early Mars, 1st-5th International Conferences on Mars Polar Science and Exploration, and the Conference on the Geophysical Detection of Subsurface Water on Mars. Steve is the Deputy Science Team Leader for the WISDOM Ground Penetrating Radar which is part of the payload of ESA's 2020 ExoMars Rover. He is also a U.S. Participating Scientist on the MARSIS orbital radar sounder on ESA's Mars Express mission. Prior to joining the science staff at PSI in February 2018, Steve was a Senior Staff Scientist at the Lunar and Planetary Institute in Houston, Texas, where he conducted his Mars research for 34 years.
