The Great Sand Sea in Egypt presents the history of one of the large sand seas in the Sahara, beginning with the sand supply by fluvial transport from partly distant areas and also by local sandstone weathering. It also details sand as carrier of information and shows the possibilities of sedimentary analysis in dealing with such a topic. Simple measurements may supply important information (e.g. salinity measurements). Well known methods can be developed further to answer special questions. A wealth of information can be drawn from especially adapted sedimentological investigations. In the end, bits of information from different analytical sources can be put together to reveal the history of a large sand sea. *Analyzes different geological sources to decipher the history of the Great Sand Sea *Presents the possibilities of sedimentary analysis to interpret the history of an area *Develops well-known methods to further answer special questions

This volume presents the results of a long study begun in 2004 within the framework of the Archaeological Mission in the Farafra Oasis of Egypt directed by Barbara Barich and Giulio Lucarini, of the Sapienza University of Rome (now under the auspices of ISMEO). The book focuses on the features known as “Steinplatz-type hearths” and their role in the settlement patterns of the human groups living in the Egyptian Western Desert during the middle and late Holocene. Steinplätze are concentrations of burned and fire-cracked stones that vary in shape and size, and have often been slightly elevated above the present ground level by post-depositional erosion processes. Occurring both as isolated features and in clusters, they are often the only visible structures – or even traces – of ancient settlements. The study of these features is closely interconnected with the mobility strategies of the communities that inhabited this desert region during a period of higher average rainfall than at present but also characterised by significant climate fluctuations, with humid periods interrupted by dry spells and eventually ending in an overall trend towards greater desertification. The use of the Steinplatz-type hearths was most widespread in the second half of the sixth millennium BC, when mobile occupation strategies replaced a more sedentary model. An analysis of the Farafra Oasis Steinplätze is coupled with a general reassessment of the subsistence and mobility models hitherto proposed for the Eastern Sahara, suggesting an integrated occupation system for Farafra itself. The economy of the forager-herders of the middle Holocene, during the climate optimum (6900-5550 cal BC), seems to have relied significantly on herding small livestock, but also on hunting, and likely concentrated on the gathering of wild cereals such as sorghum. During the climate optimum, forms of seasonal stabilisation of the settlement strategy seem to emerge, with the alternating occupation of two different winter and summer villages consisting of clusters of stone-slab huts; short-term task-specific camps, using Steinplätze, logistically completed the system. After this phase, only short-term camps with Steinplätze were occupied. These were probably directly dependent on the wettest areas at the centre of the oases and made use of a tethered exploitation strategy, with brief movements from the central oasis (“daisy-chain” movements). The use strategies of the Steinplatz-type hearths within the mobile settlement system are outlined adopting a clear and immediately assessable model. “Yet although they are among the most distinctive of the Sahara’s archaeological features, Steinplätze have received little systematic attention in recent decades. Marina Gallinaro’s work thus marks a new phase in their study, one that draws them back into discussions of how early livestock-keeping populations in Northeast Africa used the resources and landscapes to the west of the Nile along a trajectory of increasing aridification that eventually culminated in the desert we see today (…) Lucidly written, Gallinaro’s volume will, I believe, help inspire individuals to take up the research agenda she sets out. At a time when so much of the Sahara is off-limits to archaeological fieldwork, it is deeply gratifying to see here yet more evidence of the thoroughness and high quality that have characterized the work of Italian archaeologists in this region of Africa over many decades. The continuing publication of their research, Marina Gallinaro’s included, in the Arid Zone Archaeology monograph series will surely help sustain widespread interest in Saharan archaeology until it becomes possible to excavate and survey again free of current geopolitical restrictions. May that day come soon!” Prof. Peter Mitchell, University of Oxford, UK.

Made up of members of the Coldstream and Scots Guards, British Yeomanry cavalry regiments, New Zealanders, South Africans, and Indian Army men, the Long Range Desert Group was perhaps the most effective of all the "special forces" established by the Allies during the Second World War. It was able to go thousands of miles into enemy territory, well-armed and carrying its own supplies of petrol, food and even water to last for weeks at a time - something quite new in military history. Using experience acquired in WWI and inter-war exploration travels, the LRDG thus developed the ability to appear almost anywhere in the desert to carry out almost every type of ground reconnaissance mission possible in desert warfare, exploring and mapping the terrain, transporting agents behind enemy lines or determining the strength and location of enemy forces with an extraordinary degree of accuracy and detail and thus able to verify or hide Ultra intelligence. Equally important were their skills in the art of desert navigation, demonstrated in the outflanking of the enemy during the Allied advance from El Alamein westward to Tunisia, as led by the LRDG. Once it had teamed up with the Special Air Service (SAS), made up of British, Free French, Commonwealth and Jewish Palestinian soldiers, the LRDG perfected the art of irregular mechanized warfare conducted in the rear of the enemy's forces in the desert, attacking enemy installations of all kinds, mining roads, raiding airfields, destroying enemy aircraft on the ground and inflicting losses upon the enemy in inverse proportion to their own remarkably low rate of casualties. Through meticulous research in original archival material, this book thus tells the extraordinary story of how a relatively small number of dedicated men developed the methods and techniques for crossing by motor vehicle the depths of the then unmapped and seemingly impassable great deserts of Egypt and Libya, the Western Desert, during the British Army's North African Campaign of 1940-43. The Long Range Desert Group and the Special Air Service as a matter of course did extraordinary things - the heroic was the commonplace. Their tactics, techniques and remarkable success in desert warfare continue to make them of great interest to the student of military affairs. Likewise, as it seeks to answer how the deep desert can best be used for military purposes, this study is pertinent to today's military operations, perhaps more so than at any time since World War II. "…this study provides fresh insights into the nature of desert warfare, past, present and future… [and] reveals the peculiarities of this warfare often lost to modern armies… a virtual primer, useful to commanders and soldiers alike. At long last this book can find its rightful place in the classroom of military courses and colleges and in the hands of those interested in the intricacies, complexities and problems of military operations in desert regions". From the Foreword to the book by Colonel (Retired) David M. Glantz.

Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows” and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.
