Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades, the U.S. Geological Survey and the National Park Service have studied hydrothermal activity across the Yellowstone Plateau Volcanic Field (YPVF) to improve the understanding of the magmatic?hydrothermal system and to provide a baseline for detecting future anomalous activity. In 2017 and 2018 we sampled water and gas over a large area in the southwest YPVF and used Landsat 8 thermal infrared data to estimate radiative heat flow. Most of the thermal activity in this region is in close proximity to the Yellowstone Caldera boundary. Springs and fumaroles discharge from a variety of lithologies, including some of the youngest rhyolites in the YPVF. Gas compositions and helium isotope ratios of most samples resemble those in other parts of the YPVF. The waters have meteoric origins, and tritium was detected in several samples. Thermal waters from some areas have compositions that plot along a line connecting thermal and nonthermal water endmember compositions. The thermal water endmember equilibrated at 160°C?170°C, lower than waters in Yellowstone's geyser basins. Heat discharged by springs and fumaroles originates from within the Yellowstone Caldera and is transported laterally by advection, mainly along the base of rhyolite flows that cover the inferred caldera boundaries.

This book was released on 2014 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maps that define the current distribution of geothermally heated ground are useful toward setting a baseline for thermal activity to better detect and understand future anomalous hydrothermal and (or) volcanic activity. Monitoring changes in the dynamic thermal areas also supports decisions regarding the development of Yellowstone National Park infrastructure, preservation and protection of park resources, and ensuring visitor safety. Because of the challenges associated with field-based monitoring of a large, complex geothermal system that is spread out over a large and remote area, satellite-based thermal infrared images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) were used to map the location and spatial extent of active thermal areas, to generate thermal anomaly maps, and to quantify the radiative component of the total geothermal heat flux. ASTER thermal infrared data acquired during winter nights were used to minimize the contribution of solar heating of the surface. The ASTER thermal infrared mapping results were compared to maps of thermal areas based on field investigations and high-resolution aerial photos. Field validation of the ASTER thermal mapping is an ongoing task. The purpose of this report is to make available ASTER-based maps of Yellowstone?s thermal areas. We include an appendix containing the names and characteristics of Yellowstone?s thermal areas, georeferenced TIFF files containing ASTER thermal imagery, and several spatial data sets in Esri shapefile format.

Download or read book Spatial and Temporal Study of Heat Transport of Hydrothermal Features in Norris Geyser Basin, Yellowstone National Park written by Ruba A. M. Mohamed and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring thermal activity in Yellowstone National Park is required by the United States Congress to maintain the safety of the visitors and park service personnel and to protect the integrity of the park. This dissertation is part of a study initiated in the early 2000s to monitor the thermal activity in the park with focus on Norris Geyser Basin, the hottest geyser basin in the park. The study is considered the first multiple-year study in the basin which took place between August 2008 and October 2013. In this study, at least one thermal infrared image was acquired every year using airborne remote sensing tools to estimate the surface radiant temperature. The images were used to estimate and compare changes in surface radiant temperature and other radiant components including radiant flux and radiant power, which were estimated from the radiant temperature images over Norris. To compare yearly changes in the radiant flux due to the thermal source alone, the stored solar flux was estimated and subtracted from the total radiant flux image. Two methods were suggested in this dissertation to estimate the stored solar flux which were addressed in Chapters 2 and 4. The assumptions and implications of each method were discuss to suggest a reliable method to estimate the geothermal heat flux.

Download or read book Hydrothermal Monitoring in Yellowstone National Park Using Airborne Thermal Infrared Remote Sensing written by Christopher M. U. Neale and published by . This book was released on 2016 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the image acquisition and processing methodology, including surface emissivity and atmospheric corrections, for generating surface temperatures of two active hydrothermal systems in Yellowstone National Park. Airborne thermal infrared (8?12 ?m) images were obtained annually from 2007 to 2012 using a FLIR SC640 thermal infrared camera system. Thermal infrared image acquisitions occurred under clear-sky conditions after sunset to meet the objective of providing high-spatial resolution, georectified imagery for hydrothermal monitoring. Comparisons of corrected radiative temperature maps with measured ground and water kinetic temperatures at flight times provided an assessment of temperature accuracy. A repeatable, time-sequence of images for Hot Spring Basin (2007?2012) and Norris Geyser Basin (2008?2012) documented fracture-related changes in temperature and fluid flow for both hydrothermal systems, highlighting the utility of methods for synoptic monitoring of Yellowstone National Park's hydrothermal systems.

Download or read book Use of ASTER and MODIS Thermal Infrared Data to Quantify Heat Flow and Hydrothermal Change at Yellowstone National Park written by R. Greg Vaughan and published by . This book was released on 2012 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overarching aim of this study was touse satellite thermalinfrared (TIR) remote sensing to monitor geothermal activity within the Yellowstone geothermal area to meet the missions of both the U.S. Geological Survey and the Yellowstone National Park Geology Program. Specific goals were to: 1) address the challenges of monitoring the surface thermal characteristics of the > 10,000 spatially and temporally dynamic thermal features in the Park (including hot springs, pools, geysers, fumaroles, and mud pots) that are spread out over ~ 5000 km2, by using satellite TIR remote sensing tools (e.g., ASTER and MODIS), 2) to estimate the radiant geothermal heat flux (GHF) for Yellowstone's thermal areas, and 3) to identify normal, background thermal changes so that significant, abnormal changes can be recognized, should they ever occur (e.g., changes related to tectonic, hydrothermal, impending volcanic processes, or human activities, such as nearby geothermal development). ASTER TIR data (90-m pixels) were used to estimate the radiant GHF from all of Yellowstone's thermal features and update maps ofthermal areas. MODIS TIR data (1-km pixels) were used to record background thermal radiance variations from March 2000 through December 2010 and establish thermal change detection limits. A lower limit for the radiant GHF estimated from ASTER TIR temperature data was established at ~ 2.0 GW, which is ~ 30?45% of the heat flux estimated through geochemical thermometry. Also, about 5 km2ofthermal areas was added to the geodatabase of mapped thermal areas. A decade-long time-series ofMODIS TIR radiance data was dominated by seasonal cycles. A background subtraction technique was used in an attempt to isolate variations due to geothermal changes. Several statistically significant perturbations were noted in the time-series from Norris Geyser Basin, however many of these did not correspond to documented thermal disturbances. This study provides concrete examples of the strengths and limitations of current satellite TIR monitoring of geothermal areas, highlighting some specific areas that can be improved. This work provides a framework for future satellite-based thermal monitoring at Yellowstone and other volcanic and geothermal systems.

This book was released on 2018 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique that utilizes radiative power from airborne night-thermal infrared imagery is described for monitoring Norris Geyser Basin in Yellowstone National Park. This technique does not define the total corrected radiative power emitted from hydrothermal areas. Instead, the uncorrected geothermal power for geohydrologic areas is compared to quantitatively document temporal changes in specific hydrothermal areas. Power-temperature histograms for geohydrologic areas illustrate hydrothermal characteristics of geohydrologic areas and document hydrothermal changes.
