Department Of Energy Programmatic Spent Nuclear Fuel Management And Idaho National Engineering Laboratory Environmental Restoration And Waste Management Programs Final Environmental Impact Statement, Volume 1, United States Department Of Energy

All U.S. Government Documents (Utah Regional Depository)

The U.S. Department of Energy (DOE) is evaluating its options for two separate but related sets of decisions pertinent to the mangement of the spent nuclear fuel (SNF) for which the DOE is responsible. As a result, this Environmental Impact Statemt (EIS) is divided into two parts. Volume 1 involves programmatic (DOE-wide) approaches to the management of DOE's SNF. Volume 2 discusses site-specific approaches for environmental restoration and waste management activities at the Idaho National Engineering Laboratory, including SNF management. This EIS has been prepared in accordance with the National Environmental Policy Act and its applicable implementing regulations (40 CFR …

Department Of Energy Programmatic Spent Nuclear Fuel Management And Idaho National Engineering Laboratory Environmental Restoration And Waste Management Programs Final Environmental Impact Statement, Volume 2, Part A, United States Department Of Energy

All U.S. Government Documents (Utah Regional Depository)

This document analyzes at a programmatic level the potential environmental consequences over the next 40 years of alternatives related to the transportation, receipt, processing, and storage of spent nuclear fuel under the responsibility of the U.S. Department of Energy. It also analyzes the site-specific consequences of the Idaho National Engineering Laboratory sitewide actions anticipated over the next 10 years for waste and spent nuclear fuel management and environmental restoration. For programmatic spent nuclear fuel management, this document analyzes alternatives of no action, decentralization, regionalization, centralization and the use of the plans that existed in 1992/1993 for the management of these …

Source Of The Northeastern Idaho Batholith: Isotopic Evidence For A Paleoproterozoic Terrane In The Northwestern U.S., Paul A. Mueller, Robert Duncan Shuster, K. A. D'Arcy, A. L. Heatherington, A. P. Nutman, I. S. Williams

Geography and Geology Faculty Publications

The northeastern portion of the Idaho batholith (NIB) intruded Proterozoic rocks of the Belt-Purcell supergroup between SO and 90 Ma. Whole-rock Sm-Nd isotopic analyses of batholithic rocks yield depleted mantle model ages (T oM) between 1. 72 and 1.93 Ga and values of eNd between -17. 7 and - 21.2, similar to associated metamorphic rocks and within the range for Belt-Purcell sedimentary rocks. Premagmatic zircons from one sample of the NIB were analyzed individually using the SHRIMP ion microprobe and yielded a single age population at 1.74 Ga. This apparently single-aged source contrasts with the range of ages reported for …

Bermuda Solution Pipe Soils: A Geochemical Evaluation Of Eolian Parent Materials, Stanley R. Herwitz, Daniel R. Muhs

United States Geological Survey: Staff Publications

Solution pipes found in the Quaternary eolian and marine carbonates of Bermuda are filled with reddish to reddish-brown soil material. The bulk of the soil is composed of clay and silt-sized quartz and aluminosilicate clay minerals. The carbonates are of high purity and, therefore, are not likely to have been the parent material. Previous workers have hypothesized that Saharan dust may have been the soil parent material. The fine-grained component of loess from the Mississippi River Valley of North America also could have contributed. Paleoclimate models indicate that both North Africa and North America could have been important source areas …

Evidence Of Active Dune Sand On The Great Plains In The 19th Century From Accounts Of Early Explorers, Daniel R. Muhs, Vance T. Holliday

United States Geological Survey: Staff Publications

Eolian sand is extensive over the Great Plains of North America, but is at present mostly stabilized by vegetation. Accounts published by early explorers, however, indicate that at least parts of dune fields in Nebraska, Colorado, Kansas, New Mexico, and Texas were active in the 19th century. Based on an index of dune mobility and a regional tree-ring record, the probable causes for these periods of greater eolian activity are droughts, accompanied by higher temperatures, which greatly lowered the precipitationto- evapotranspiration ratio and diminished the cover of stabilizing vegetation. In addition, observations by several explorers, and previous historical studies, indicate …

Freezing And Thawing Of Agricultural Soils: Implications For Soil, Water, And Air Quality, Brenton S. Sharratt, Keith E. Saxton, Jerry K. Radke

Journal of the Minnesota Academy of Science

Most agricultural lands in the USA are subject to subfreezing temperatures. Soil freezing and thawing affects both biotic and abiotic interactions and processes which vary with weather, soil type, land management, and topography. Soil fauna generally undergo physiological changes or rely on locomotion as a means of adapting to frozen soils. Managing faunal populations using soil management may be achievable with a better understanding of winter ecological processes. Many of the thermal, hydraulic, mechanical, and physical properties of soils are altered by freezing and thawing. Soil erosion may be accentuated by soil freezing and thawing as a result of changes …

Preliminary Map Of The Structure Of The Precambrian Surface In Eastern Kentucky, James A. Drahovzal, Martin C. Noger

Map and Chart--KGS

This preliminary interpretation of the Precambrian unconformity surface in eastern Kentucky is based on data available to the Kentucky Geological Survey (KGS) as of November 1994. In early 1995, additional data became available to the KGS. Subsequent work using the new data should result in a more complete interpretation of the area within the next several years.

The map illustrates the Rome Trough and associated structures of the Precambrian surface, and as such contributes to an understanding of the regional geology, geologic evolution, distribution of energy and mineral resources, and potential geologic hazards. While it cannot be considered a prospecting …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …

Strontium Isotope Stratigraphy And Age Estimates For The Leisey Shell Pit Faunas, Hillsborough County, Florida, Douglas S. Jones, Paul A. Mueller, Teresa Acosta, Robert Duncan Shuster

Geography and Geology Faculty Publications

The vertebrate fauna of the Leisey Shell Pit near Tampa Bay, Florida, represents one of the more significant lrvingtonian mammalian faunas of North America. The fossil vertebrates occur in thin bone beds bounded above and below by massive shell beds containing a rich invertebrate ( chiefly molluscan) fauna. Debate has arisen concerning the precise age of the faunas at Leisey. Although generally agreed to be Pleistocene, estimates based upon vertebrate biostratigraphy suggest a somewhat older age than do estimates based upon molluscan biostratigraphy. To help resolve this controvefliy, ⁸⁷Sr/⁸⁶Sr ratios were determined on molluscan shells throughout the …

THE ANTARCTIC marine ecosystem-the assemblage of plants, animals, ocean, sea ice, and island components south of the Antarctic Convergence is among the largest readily defined ecosystems on Earth (36 X 106 km2 ) (Hedgpeth, 1977; Petit et al., 1991). This ecosystem is composed of an interconnected system of functionally distinct hydrographic and biogeochemical subdivisions (Treguer and Jacques, 1992) and includes open ocean, frontal regions, shelf-slope waters, sea ice, and marginal ice zones. Oceanic, atmospheric, and biogeochemical processes within this system are thought to be globally significant, have been infrequently studied, and are poorly understood relative to more accessible marine ecosystems …

Modern Marine Sediments Of Bahia Concepcion: Patterns, Processes, And Potential Analogues To Neogene Rift Basin Deposits Of Baja California, Timothy William Reardon

Honors Papers

Neogene strata in Baja California preserve a record of extensional basins produced during early phases of rifting in the Gulf of California. This actualistic study addresses the feasibility of using Holocene sediments of Bahia Concepcion - a rift basin forming a shallow marine bay In southern Baja California - as analogues for the interpretation of Neogene strata in the Pliocene Loreto Basin. Three major lithofacies occur in Bahia Concepcion: Mud sediments dominate most of the central portion of the bay. Moderately sorted sands occur adjacent to shorelines formed by coalesced alluvial fans and a broad alluvial plain, while carbonate sands …

Hydrometeorological Investigations On A Small Valley Glacier In The Sawtooth Range, Ellesmere Island, Northwest Territories, Paul Michael Wolfe

Theses and Dissertations (Comprehensive)

Hydrometeorological techniques were employed during the summer of 1993 to study a small (4.7km2) valley glacier in the Sawtooth Range, Fosheim Peninsula, Ellesmere Island, Northwest Territories. The annual 1992-93 mass balance for Quviagivaa Glacier (unofficial name), and for the adjacent Nirukittuq Glacier (unofficial name) was -532mm and -530mm water equivalent respectively. The equilibrium line altitude was above the upper limit of the glaciers due to the exceptional warmth of the summer. Slight marginal shrinking in the areal extent of Quviagivaa Glacier since 1959 suggests that strongly negative mass balances such as those recorded in 1993 are not indicative of the …

A Field Investigation Of Planimetric Knickpoint Morphology From Rock-Bed Sections Of Niagara Escarpment Fluvial Systems (Ontario), Richard Stanley Pyrce

Theses and Dissertations (Comprehensive)

This study was an initial attempt to understand the impact of parents, peers, the media, and sex education curricula on shaping adolescents' knowledge and attitudes about dating relationships and sexuality. In addition, participants' descriptions of what constitutes a "good" date and a "bad" date were investigated. One hundred participants (48 females, 52 males) aged thirteen to sixteen participated: half of the sample were early adolescents (13-14 years) and the other half were middle adolescents (15-16 years). All participants were asked to describe experienced or hypothetical "good" and "bad" dates. For "good" dates, respondents identified engaging in fun, recreational activities, whereas …

Linking Landscape Ecology And Ecosystem Health: The Case Of Lunigiana, Italy, Susan Anna Pellanda

Theses and Dissertations (Comprehensive)

As ecosystem-based management is increasingly used to manage the environment, methods of applying these approaches to resolve environmental and natural resource issues must be established. The concept of ecosystem health can be used to assist in ecosystem-based management since it takes into account the environmental, economic, and social aspects of ecosystems. The aim of this thesis is to demonstrate the manner in which landscape ecology can be used to manage for the goal of obtaining a healthy ecosystem. This is achieved by studying the landscape of Lunigiana, Italy, an agricultural region located near Italy's northwestern coast. Particular emphasis is placed …

Opportunities For The Integration Of Institutional Arrangements For Riparian Buffer Zone Management In Ontario, Canada, Jeffrey Willard King

Theses and Dissertations (Comprehensive)

A need exists in Ontario for improved management of land and water resources. In addition the need for increased integration within and among the agencies responsible for these resources is imperative. Between these two resources is the riparian zone, for which riparian vegetative buffer zones are a recognized Best Management Practice (BMP) for water quality improvement. However, the problem remains that each agency views buffers from a particular perspective. Hence, butters are being implemented primarily for a single purpose without considering the multiple use of buffers. To achieve an integrated management framework for riparian buffers, it is necessary to evaluate …

Subsurface Glacial Geology Of The Area Between The Tekonsha And Kalamazoo Moraines, Kalamazoo County, Michigan, Kim Finkbeiner

Masters Theses

Cross sections profiling the stratigraphy of the glacial sediments were created using the geological logs recorded on water well records. Glacial sediments in the study area comprise a large outwash complex between two moraines. The surficial landforms are the result of the last Wisconsinan advance and retreat through the area.

Cross sections contructed for this project reveal at least three major till units. An additional till unit contains a weathered soil sequence. Therefore, it is possible that this paleosol represents the Sangamon Interglacial period between the Wisconsinan and Illinoian stages. No obvious evidence of movement of the Saginaw Lobe remains …

The Pollution Effects Of Pleasure/Work Boat Sewage Discharges On Fecal Contamination Levels Of Waters In And Around Marinas And Other Places Where Boats Are Moored On The Eastern Shore Of Virginia, George H. Bangs

Community & Environmental Health Theses & Dissertations

Contamination of seafood harvested from and recreational areas of the Chesapeake Bay, its tributaries and the Atlantic coast inshore waters may cause health problems for people consuming the seafood or coming in contact with the waters by swimming, water skiing, or other water sports. These health problems include, but not limited to, dysentery, typhoid and hepatitis (Natchez, 1990). This is a preliminary study into the level of fecal pollution generated by sewage discharges from boats in marinas and other places where boats are moored on the Eastern Shore of Virginia. Sites selected for the study included; (I) marinas and other …

Autonomous Robot Navigation In Unknown Terrains Using Parallel Numerical Artificial Potential Fields, John C. Schneider

Computer Science Theses & Dissertations

We present a new artificial potential field formulation for resolution complete robot navigation that unifies the purely geometric path planning problem with the lower level force control problem. Our formulation is designed for numerical computation over a massively parallel mesh of processors and is responsive to newly discovered terrain features. It does not suffer from many of the problems commonly associated with potential fields and with adequate resolution provides provably correct, collision free convergence to the goal. In addition, our formulation supports many desirable, practical features required for implementation, such as bounded actuator torques, attainable incremental constructability, realizable computation and …

Hydrogeological And Hydrochemical Characterization Of The Matozinhos-Pedro Leopoldo Karst, Brazil, Augusto Auler

Masters Theses & Specialist Projects

The Matozinhos-Pedro Leopoldo limestone area is a tropical karst located near the metropolis of Belo Horizonte, East Central Brazil, in an area undergoing rapid urbanization and land degradation. Qualitative dye tracing experiments have determined the groundwater routes and catchment areas in the two major drainage basins in the area, Samambaia Basin and Palmeiras-Mocambo Basin. Other drainage basins were identified, but not traced due to the absence of related swallets. Fluorescein and optical brightener had a poor performance as tracers under tropical climate. Dilution due to the existance of lakes at some swallets prevented some dye traces. The water that flows …
