This book was released on 1988 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone Lake, Wyoming is located in a tectonic 'hot spot' and lies within the Yellowstone caldera, a region with some of the highest measured geothermal heat fluxes in the world. Geothermal gradients within the lake bed are consequently very high and hydrothermal springs and hot gas fumaroles occur within the Lake itself. These features are unique in limnology and indications are that they may have a significant impact on the chemistry, nutrient dynamics, and biology of this oligotrophic system.

This book was released on 2010 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hundreds of active and dormant geothermal vents have been located on the floor of Yellowstone Lake, although characterization of the associated biology (macro or micro) has been extremely limited. Herein, we describe an aquatic moss (Fontinalis) colony closely associated with vent emissions that considerably exceeded known temperature maxima for this plant. Vent waters were supersaturated with CO(2), likely accommodating a CO(2) compensation point that would be expected to be quite elevated under these conditions. The moss was colonized by metazoa, including the crustaceans Hyalella and Gammarus, a segmented worm in the Lumbriculidae family, and a flatworm specimen tentatively identified as Polycelis. The presence of these invertebrates suggest a highly localized food chain that derives from the presence of geothermal inputs and thus is analogous to the deep marine vents that support significant biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone National Park is the site of one of the world?s largest calderas. The abundance of geothermal and tectonic activity in and around the caldera, including historic uplift and subsidence, makes it necessary to understand active geologic processes and their associated hazards. To that end, we here use an extensive grid of highresolution seismic re?ection pro?les (~450 km) to document hydrothermal and tectonic features and deposits in northern Yellowstone Lake. Sublacustrine geothermal features in northern Yellowstone Lake include two of the largest known hydrothermal explosion craters, Mary Bay and Elliott?s. Mary Bay explosion breccia is distributed uniformly around the crater, whereas Elliott?s crater breccia has an asymmetric distribution and forms a distinctive, ~2-km-long, hummocky lobe on the lake ?oor. Hydrothermal vents and low-relief domes are abundant on the lake ?oor; their greatest abundance is in and near explosion craters and along linear ?ssures. Domed areas on the lake ?oor that are relatively unbreached (by vents) are considered the most likely sites of future large hydrothermal explosions. Four submerged shoreline terraces along the margins of northern Yellowstone Lake add to the Holocene record of postglacial lakelevel ?uctuations attributed to ??heavy breathing?? of the Yellowstone magma reservoir and associated geothermal system. The Lake Hotel fault cuts through northwestern Yellowstone Lake and represents part of a 25-km-long distributed extensional deformation zone. Three postglacial ruptures indicate a slip rate of ~0.27 to 0.34 mm/yr. The largest (3.0 m slip) and most recent event occurred in the past ~2100 yr. Although high heat ?ow in the crust limits the rupture area of this fault zone, future earthquakes of magnitude ~5.3 to 6.5 are possible. Earthquakes and hydrothermal explosions have probably triggered landslides, common features around the lake margins. Few high-resolution seismic re?ection surveys have been conducted in lakes in active volcanic areas. Our data reveal active geothermal features with unprecedented resolution and provide important analogues for recognition of comparable features and potential hazards in other subaqueous geothermal environments.

Download or read book Biological Nitrogen Fixation in Acidic High temperature Geothermal Springs in Yellowstone National Park Wyoming written by Trinity Lynn Hamilton and published by . This book was released on 2011 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The near ubiquitous distribution of nifH genes in sediments sampled from 14 high-temperature (48.0-89.0C) and acidic (pH 1.90-5.02) geothermal springs in Yellowstone National Park suggested a role for the biological reduction of dinitrogen (N(2) to ammonia (NH(3) (e.g. nitrogen fixation or diazotrophy) in these environments. nifH genes from these environments formed three unique phylotypes that were distantly related to acidiphilic, mesophilic diazotrophs. Acetylene reduction assays and (15) N(2) tracer studies in microcosms containing sediments sampled from acidic and high-temperature environments where nifH genes were detected confirmed the potential for biological N(2) reduction in these environments. Rates of acetylene reduction by sediment-associated populations were positively correlated with the concentration of NH(4) , suggesting a potential relationship between NH(4) consumption and N(2) fixation activity. Amendment of microcosms with NH(4) resulted in increased lag times in acetylene reduction assays. Manipulation of incubation temperature and pH in acetylene reduction assays indicated that diazotrophic populations are specifically adapted to local conditions. Incubation of sediments in the presence of a N(2) headspace yielded a highly enriched culture containing a single nifH phylotype. This phylotype was detected in all 14 geothermal spring sediments examined and its abundance ranged from 780 to 6800 copies (g dry weight sediment)(-1) , suggesting that this organism may contribute N to the ecosystems. Collectively, these results for the first time demonstrate thermoacidiphilic N(2) fixation in the natural environment and extend the upper temperature for biological N(2) fixation in terrestrial systems.

Download or read book Protecting the Geyser Basins of Yellowstone National Park written by Kenneth A. Barrick and published by . This book was released on 2010 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geyser basins provide high value recreation, scientific, economic and national heritage benefits. Geysers are globally rare, in part, because development activities have quenched about 260 of the natural endowment. Today, more than half of the world?s remaining geysers are located in Yellowstone National Park, northwest Wyoming, USA. However, the hydrothermal reservoirs that supply Yellowstone?s geysers extend well beyond the Park borders, and onto two ??Known Geothermal Resource Areas???Island Park to the west and Corwin Springs on the north. Geysers are sensitive geologic features that are easily quenched by nearby geothermal wells. Therefore, the potential for geothermal energy development adjacent to Yellowstone poses a threat to the sustainability of about 500 geysers and 10,000 hydrothermal features. The purpose here is to propose that Yellowstone be protected by a ??Geyser Protection Area?? (GPA) extending in a 120-km radius from Old Faithful Geyser. The GPA concept would prohibit geothermal and large-scale groundwater wells, and thereby protect the water and heat supply of the hydrothermal reservoirs that support Yellowstone?s geyser basins and important hot springs. Proactive federal leadership, including buyouts of private groundwater development rights, can assist in navigating the GPA through the greater Yellowstone area?s ??wicked?? public policy environment. Moreover, the potential impacts on geyser basins from intrusive research sampling techniques are considered in order to facilitate the updating of national park research regulations to a precautionary standard. The GPA model can provide the basis for protecting the world?s few remaining geyser basins.

This book was released on 1996 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
