Hydrothermal Processes Above the Yellowstone Magma Chamber


Book Description

"Home to more than 10,000 thermal features, Yellowstone has experienced over 20 large hydrothermal explosions producing craters from 100 to over 2500 meters in diameter during the past 16,000 years. Using new mapping, sampling, and analysis techniques, this volume documents a broad spectrum of ages and geologic settings for these events and considers additional processes and alternative triggering mechanisms that have not been explored in previous studies. Although large hydrothermal explosions are rare on the human time scale, the potential for future explosions in Yellowstone is not insignificant, and events large enough to create a 100-m-wide crater might be expected every 200 years. This work presents information useful for determining the timing, distribution, and possible causes of these events in Yellowstone, which will aid in the planning of monitoring strategies and the anticipation of hydrothermal explosions."--Publisher's description.




Biology of Acid-sulfate-chloride Springs in Yellowstone National Park, Wyoming, United States of America


Book Description

This dissertation investigated the role of biology in several biogeochemical cycles in acid sulfate chloride (ASC) geothermal springs in Yellowstone National Park (YNP). Elemental sulfur (S°) is associated with many geothermal springs, yet little is known about the organisms involved in its cycling. The aqueous and solid phase geochemistry near the source of Dragon Spring, an ASC spring in the Norris Geyser Basin (NGB) of YNP, was used to guide the enrichment and isolation of two novel S°-reducing Crenarchaeota affiliated with the order Desulfurococcales. Both isolates are chemoorganotrophs, dependent on complex peptide-containing carbon sources, S°, and anaerobic conditions for respiration-dependent growth. Physiological characterization suggests the isolates are adapted to the physicochemical conditions of Dragon Spring which is supported by quantitative PCR analysis which indicates that the isolates represent a significant fraction of the microbial community associated with S° precipitates in several ASC geothermal springs in the NGB in YNP.

Chemical Analyses of Hot Springs, Pools, and Geysers from Yellowstone National Park, Wyoming, and Vicinity, 1980-1993


Book Description

Waters from hot springs, pools, and geysers have been analyzed by numerous investigators throughout the history of Yellowstone National Park. The chemistry of the more easily accessible major geyser basins and a significant number of Yellowstone thermal waters on the eastern side of the Yellowstone River has been compiled by Gooch and Whitfield (1888), Allen and Day (1935), Rowe andothers (1973), Thompson and others (1975), Thompson and Yadav (1979), and Kharaka and others (1992). The first comprehensive study of Shoshone Geyser Basin was made by A.H. Truesdell in 1972-73 (Truesdell and Thompson, 1982). Many of the concepts presented in that report are applicable to other Yellowstone thermal areas. Locations of the major thermal water basins mentioned in this report can be found in Figure 1. The collection of data on the hot and cold springs of Yellowstone National Park is important in understanding the geothermal chemistry of this system. Geochemical changes that occur over time, the disappearance of existing springs, the appearance of new ones and geochemical changes in spring waters prior to earthquakes, can be monitored. Especially important are those springs for which there is little or no data.-Introduction.




Microbial Life of the Deep Biosphere


Book Description

Over the last two decades, exploration of the deep subsurface biosphere has developed into a major research area. New findings constantly challenge our concepts of global biogeochemical cycles and the ultimate limits to life. In order to explain our observations from deep subsurface ecosystems it is necessary to develop truly interdisciplinary approaches, ranging from microbiology and geochemistry to physics and modeling. This book aims to bring together a wide variety of topics, covering the broad range of issues that are associated with deep biosphere exploration. Not only does the book present case studies of selected projects, but also treats questions arising from our current knowledge. Despite nearly two decades of research, there are still many boundaries to exploration caused by technical limitations and one section of the book is devoted to these technical challenges and the latest developments in this field. This volume will be of high interest to biologists, chemists and earth scientists all working on the deep biosphere.
