Download or read book High Temperature Hydrothermal Vent Fluids in Yellowstone Lake Observations and Insights from In situ PH and Redox Measurements written by Chunyang Tan and published by . This book was released on 2017 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: ROV investigation of hydrothermal fluids issuing from vents on the floor of Yellowstone lake revealed temperatures in excess of 170 °C ? the highest temperature yet reported for vent fluids within Yellowstone National Park (YNP). The study site is east of Stevenson Island at depth of approximately 100?125 m. In-situ pH and redox measurements of vent fluids were made using solid state sensors designed to sustain the elevated temperatures and pressures. YSZ membrane electrode with Ag/Ag2O internal element and internal pressure balanced Ag/AgCl reference electrode were used to measure pH, while a platinum electrode provided redox constraints. Lab verification of the pH sensor confirmed excellent agreement with Nernst law predictions, especially at temperatures in excess of 120 °C. In-situ pH values of between 4.2 and 4.5 were measured for the vent fluids at temperatures of 120 to 150 °C. The slightly acidic vent fluids are likely caused by CO2 enrichment in association with magmatic degassing effects that occur throughout YNP. This is consistent with results of simple model calculations and direct observation of CO2 bubbles in the immediate vicinity of the lake floor vents. Simultaneous redox measurements indicated moderate to highly reducing conditions (? 0.2 to ? 0.3 V). As typical of measurements of this kind, internal and external redox disequilibria likely preclude unambiguous determination of redox controlling reactions. Redox disequilibria, however, can be expected to drive microbial metabolism and diversity in the near vent environment. Thus, the combination of in-situ pH and redox sensor deployments may ultimately provide the requisite framework to better understand the microbiology of the newly discovered hot vents on Yellowstone lake floor.
Download or read book Death in Yellowstone written by Lee H. Whittlesey and published by Roberts Rinehart. This book was released on 2014-01-07 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chilling tome that launched an entire genre of books about the often gruesome but always tragic ways people have died in our national parks, this updated edition of the classic includes calamities in Yellowstone from the past sixteen years, including the infamous grizzly bear attacks in the summer of 2011 as well as a fatal hot springs accident in 2000. In these accounts, written with sensitivity as cautionary tales about what to do and what not to do in one of our wildest national parks, Whittlesey recounts deaths ranging from tragedy to folly—from being caught in a freak avalanche to the goring of a photographer who just got a little too close to a bison. Armchair travelers and park visitors alike will be fascinated by this important book detailing the dangers awaiting in our first national park.
Download or read book Hydrothermal and Tectonic Activity in Northern Yellowstone Lake Wyoming written by Samuel Y. Johnson and published by . This book was released on 2003 with total page 18 pages. 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 Is Earth Exceptional written by Dr. Mario Livio and published by Basic Books. This book was released on 2024-09-10 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New York Times–bestselling astrophysicist and a Nobel laureate describe the quest to discover how and where the universe breathed life into matter For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now. It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?, the veil is finally lifting. The authors describe how life’s building blocks—from RNA to amino acids and cells—could have emerged from the chaos of Earth’s early existence. They then apply the knowledge gathered from cutting-edge research across the sciences to the search for life in the cosmos: both life as we know it and life as we don’t. Why and where life exists are two of the biggest unsolved problems in science. Is Earth Exceptional? is the ultimate exploration of the question of whether life is a freak accident or a chemical imperative.

Download or read book A Geothermal linked Biological Oasis in Yellowstone Lake Yellowstone National Park Wyoming written by David Lovalvo and published by . 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.
