Provisional maps of thermal areas in Yellowstone National Park, based on satellite thermal infrared imaging and field observations Provisional maps of thermal areas in Yellowstone National Park, based on satellite thermal infrared imaging and field observations
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...

Quality of groundwater in the Denver Basin aquifer system, Colorado, 2003-5 Quality of groundwater in the Denver Basin aquifer system, Colorado, 2003-5
Groundwater resources from alluvial and bedrock aquifers of the Denver Basin are critical for municipal, domestic, and agricultural uses in Colorado along the eastern front of the Rocky Mountains. Rapid and widespread urban development, primarily along the western boundary of the Denver Basin, has approximately doubled the population since about 1970, and much of the population depends...

Quality of surface-water supplies in the Triangle area of North Carolina, water year 2009 Quality of surface-water supplies in the Triangle area of North Carolina, water year 2009
Surface-water supplies are important sources of drinking water for residents in the Triangle area of North Carolina, which is located within the upper Cape Fear and Neuse River Basins. Since 1988, the U.S. Geological Survey and a consortium of governments have tracked water-quality conditions and trends in several of the area’s water-supply lakes and streams. This report summarizes data...

Quantifying benthic nitrogen fluxes in Puget Sound, Washington: a review of available data Quantifying benthic nitrogen fluxes in Puget Sound, Washington: a review of available data
Understanding benthic fluxes is important for understanding the fate of materials that settle to the Puget Sound, Washington, seafloor, as well as the impact these fluxes have on the chemical composition and biogeochemical cycles of marine waters. Existing approaches used to measure benthic nitrogen flux in Puget Sound and elsewhere were reviewed and summarized, and factors for...

Rancher and farmer quality of life in the midst of energy development in southwest Wyoming Rancher and farmer quality of life in the midst of energy development in southwest Wyoming
Quality of life (QOL) is usually defined as a person’s general well-being, and may include individual perceptions of a variety of factors such family, work, finances, local community services, community relationships, surrounding environment, and other important aspects of their life, ultimately leading to life satisfaction. Energy development can have an effect on QOL components for...
