This book was released on 2017-05-23 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanoes sometimes host a lake at the Earth's surface. These lakes are the surface expressions of a reservoir, often termed a hydrothermal system, in highly fractured, permeable and porous media where fluids circulate. They can become monitoring targets since they integrate the heat flux discharged by an underlying magma body and condense some volcanic gases. Since they trap volcanic heat and gases, they are excellent tools to provide additional information about the status of a volcano and volcanic lake-related hazards. This Special Publication comes at an exciting time for the volcanic lake community. It brings together scientific papers, which include studies of their structure, hydrogeological modelling, long-term multi-disciplinary monitoring efforts, as well as a number of innovative methods of sampling, data acquisition and in situ and laboratory experiments. Several papers challenge long-established paradigms and introduce new concepts and terminologies. This collection of papers will be a useful reference for researchers dealing with volcanic lakes and more generally with hydrothermal systems, phreatic/hydrothermal eruptions and wet volcanoes.

Book excerpt: On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critical evidence to address this question in ancient lakebeds as clues about Mars’ climate evolution and its habitability potential are still preserved in their sedimentary record. Lakes on Mars is the first review on this subject. It is written by leading planetary scientists who have dedicated their careers to searching and exploring the questions of water, lakes, and oceans on Mars through their involvement in planetary exploration, and the analysis of orbital and ground data beginning with Viking up to the most recent missions. In thirteen chapters, Lakes on Mars critically discusses new data and explores the role that water played in the evolution of the surface of Mars, the past hydrological provinces of the planet, the possibility of heated lake habitats through enhanced geothermal flux associated with volcanic activity and impact cratering. The book also explores alternate hypotheses to explain the geological record. Topographic, morphologic, stratigraphic, and mineralogic evidence are presented that suggest successions of ancient lake environments in Valles Marineris and Hellas. The existence of large lakes and/or small oceans in Elysium and the Northern Plains is supported both by the global distribution of deltaic deposits and by equipotential surfaces that may reflect their past margins. Whether those environments were conducive to life has yet to be demonstrated but from comparison with our planet, their sedimentary deposits may provide the best opportunity to find its record, if any. The final chapters explore the impact of climate variability on declining lake habitats in one of the closest terrestrial analogs to Mars at the Noachian/Hesperian transition, identify the geologic, morphologic and mineralogic signatures of ancient lakes to be searched for on Mars, and present the case for landing the Mars Science Laboratory mission in such an environment. First review on the subject by worldwide leading authorities in the field New studies with most recent data, new images, figures, and maps Most recent results from research in terrestrial analogs

Download or read book Late Cenozoic Lava Dams in the Western Grand Canyon written by William Kenneth Hamblin and published by Geological Society of America. This book was released on 1994 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Late Cenozoic history of the western Grand Canyon is one of profound and rapid transformation. The constantly changing morphology and dynamics of the canyon during this period have been recorded in spectacular geologic features, such as frozen lava cascades and lava dams, as well as volcanic cones, necks, and dikes. All of these unique features, which make the western part of the Grand Canyon strikingly different from other parts, resulted from the interaction of basaltic lava flows and vigorous erosion by the Colorado River. The volcanic phenomena in the Grand Canyon were created by eruptions of basaltic lava in the southernmost part of the Uinkaret volcanic field. Some lava flows were extruded on the Uinkaret Plateau and cascaded over the outer rim of the Grand Canyon into Toroweap Valley and Whitmore Wash, while others were extruded within the Grand Canyon itself and partly covered the Esplanade Platform. The remaining flows cascaded over the rim of the canyon's inner gorge. Red molten rock cascading into the canyon and forming lava dams must have presented a spectacular scene, the likes of which have never been viewed by human beings. Even more spectacular is how quickly these lava dams formed - from small single-flow dams that were created in only a few days, to complex, multiple-flow dams that took several thousand years. The dams were then destroyed when the water impounded behind them ultimately overflowed. Although their construction and destruction occurred in a geologic instant, these events were the most significant in the late Cenozoic history of the Grand Canyon. Because of the largely inaccessible nature of the western part of the canyon, the author and his field assistants researching this area had to be creative in their data-gathering techniques. For example, they made photo mosaics of the entire canyon wall using a hand-held aerial camera; these mosaics served as cross sections on which all geological data were plotted. In addition, to photograph features hidden from view at river level, they utilized light aircraft and helicopters. Finally, a professional mountain climber collected samples from various units exposed high on vertical cliffs. Memoir 183 is a compilation of this field work, which took more than two decades to complete. It contains numerous maps, photographs, and cross sections of frozen lava cascades and the remnants of a sequence of 13 major lava dams that once formed huge barriers to the Colorado River. The volume also discusses the history of lakes that formed behind these lava dams and the associated sedimentary deposits that once partly filled the Grand Canyon. The results of this study provide new insights into the rates at which the Colorado River is able to downcut its channel, as well as the major factors that controlled erosion of the Grand Canyon.

Book excerpt: This open access book summarizes the findings of the VUELCO project, a multi-disciplinary and cross-boundary research funded by the European Commission's 7th framework program. It comprises four broad topics: 1. The global significance of volcanic unrest 2. Geophysical and geochemical fingerprints of unrest and precursory activity 3. Magma dynamics leading to unrest phenomena 4. Bridging the gap between science and decision-making Volcanic unrest is a complex multi-hazard phenomenon. The fact that unrest may, or may not lead to an imminent eruption contributes significant uncertainty to short-term volcanic hazard and risk assessment. Although it is reasonable to assume that all eruptions are associated with precursory activity of some sort, the understanding of the causative links between subsurface processes, resulting unrest signals and imminent eruption is incomplete. When a volcano evolves from dormancy into a phase of unrest, important scientific, political and social questions need to be addressed. This book is aimed at graduate students, researchers of volcanic phenomena, professionals in volcanic hazard and risk assessment, observatory personnel, as well as emergency managers who wish to learn about the complex nature of volcanic unrest and how to utilize new findings to deal with unrest phenomena at scientific and emergency managing levels.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents recent advances in the research on meromictic lakes and a state-of-the art overview of this area. After an introduction to the terminology and geographic distribution of meromictic lakes, three concise chapters describe their physical, chemical and biological features. The following eight chapters present case studies of more than a dozen meromictic lakes, showing the variety of physical and biochemical processes that promote meromixis. The result is a broad picture of the ecology and biochemistry of meromictic lakes in tropical and cold regions, in man-made pit lakes and euxinic marine lakes, and in freshwater as well as hypersaline lakes. In the final chapter the editors provide a synthesis of the topic and conclude that the study of meromictic lakes also offers new insights into the limnology of inland lakes. The book appeals to researchers in the fields of ecology, limnology, environmental physics and biophysics.
