This book describes how sand dunes work, why they are the way they are in different settings, and how they are being studied. Particular attention is paid to their formation and appearance elsewhere in the solar system. New developments in knowledge about dunes make for an interesting story – like the dunes themselves, dune science is dynamic – and the visual appeal of Aeolian geomorphology ensures that this is an attractive volume. The book is divided into 4 parts, the first of which introduces dunes as a planetary phenomenon, showing a landscape reflecting the balance of geological processes – volcanism, impact, tectonics, erosion, deposition of sediments. Dunes are then considered as emergent dynamical systems: the interaction of sand and wind conspires to generate very characteristic and reproducible shapes. Analogies are given with other emergent structures such as patterned ground before the influence of dunes on desert peoples and infrastructure is studied, together with their use as forensic climatological indicators. Dune Physics is looked at with regard to the mechanics of sand, the physics of wind, saltation – interaction of sand and air – dunes versus ripples and transverse Aeolian ridges, the classification of dune morphology and the sources and sinks of sand. Dune Trafficability considers soil mechanics, effects on mobility on Earth, Mars and elsewhere. In the second part, Earth, Mars, Titan and other moons and planets are examined, beginning with a survey of the major deserts and dunefields on Earth. The authors then turn to Mars and its environment, sediment type, dune stratigraphy, sediment source and sinks and the association of dunes with topographic features. Titan follows - its thick, cold atmosphere, methane dampness, low gravity, morphology – interaction with topography and the implications of dunes for climate and winds. Dunes elsewhere conclude this part. There are few dunefields on Venus, but there is a .possibility of Aeolian transport on Triton and volcanic-related windstreaks on Io.

This completely revised and enlarged second edition provides an up-to-date overview of all major topics in sedimentary geology. It is unique in its quantitative approach to denudation-accumulation systems and basin fillings, including dynamic aspects. The relationship between tectonism and basin evolution as well as the concepts of sequence cycle and event stratigraphy in various depositional environments are extensively discussed. Numerous, often composite figures, a well-structured text, brief summaries in boxes, and several examples from all continents make the book an invaluable source of information for students, researchers and professors in academia as well as for professionals in the oil industry.

I chose the title A Poemers Poemerings because it means (for me) that of someone to whom is always writing about something, anything. And its odd and catchy at the same time, and its the main title for the series that I am writing in volumes, too many to put all into one book. I think of my poems, all as individual artworks, own a completenessfrom start to finisha journey, a path, a message that will inspire, mesmerize, intrigue, and take you to that deepness that hasnt been felt or known of your own self. Allow yourself to think out there and to see what each one is telling you! Envision the poem, and let yourself see the answers to your own thoughts of these pieces of artworks.

Gereint Enseichen of Casmantium knows little and cares less about the recent war in which his king tried to use griffins and fire to wrest territory from the neighboring country of Feierabiand. . .but he knows that his kingdom's unexpected defeat offers him a chance to escape from his own servitude. But now that the griffins find themselves in a position of strength, they are not inclined to forgive and the entire kingdom finds itself in deadly peril. Willing or not, Gereint will find himself caught up in a desperate struggle between the griffins and the last remaining Casmantian mage. Even the strongest gifts of making and building may not prove sufficient when the fiery wind of the griffins begins to bury the life of Casmantium beneath the burning sands . . .
