Electricity Deregulation And The Valuation Of Visibility Loss In Wilderness Areas: A Research Note., John M. Halstead, Thomas H. Stevens, Wendy Harper, L Bruce Hill

Natural Resources & the Environment

Visibility in most wilderness areas in the northeastern United States has declined substantially since the 1970s. As noted by Hill et al. (2000), despite the 1977 Clean Air Act and subsequent amendments, human induced smog conditions are becoming increasingly worse. Average visibility in class I airsheds, such as the Great Gulf Wilderness in New Hampshire’s White Mountains, is now about one-third of natural conditions. A particular concern is that deregulation of electricity production could result in further degradation because consumers may switch to lower cost fossil fuel generation (Harper 2000). To the extent that this system reduces electricity costs, it …

Teaching For Change: The Leadership In Environmental Education Partnership, Paul Faulstich

Pitzer Faculty Publications and Research

Humans are transforming earth's landscape from a natural matrix with pockets of civilization to just the opposite. Most of us realize that this pattern is not sustainable. I live and work in Claremont, California, a charming college town in the midst of suburban sprawl. The town has a central village of terminally tasteful, overpriced bungalows nestled in the shade of tall, largely exotic trees. Indeed, most of the landscape of this "city of trees and Ph.D.s" has been imported; only a remnant parcel of coastal sage scrub that the Claremont Colleges have reluctantly preserved remains.

An Analysis Of Simulated Long-Term Soil Moisture Data For Three Land Uses Under Contrasting Hydroclimatic Conditions In The Northern Great Plains, Rezaul Mamood, Kenneth G. Hubbard

High Plains Regional Climate Center: Staff Publications

Soil moisture (SM) plays an important role in land surface and atmosphere interactions. It modifies energy balance near the surface and the rate of water cycling between land and atmosphere. The lack of observed SM data prohibits understanding of SM variations at climate scales under varying land uses. However, with simulation models it is possible to develop a long-term SM dataset and study these issues. In this paper a water balance model is used to provide a quantitative assessment of SM climatologies for three land uses, namely, irrigated corn, rain-fed corn, and grass, grown under three hydroclimatic regimes in Nebraska. …

Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood

Resource management technical reports

A production bore in Kellerberrin, Western Australia, was test pumped for 24 hours in August 2003. Data generated by the pumping were analysed with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate a low pH and very high levels of salinity, hardness, sodium, chloride, iron, sulphate, aluminium and manganese. This is likely to lead to scaling, blockages, staining and/or corrosion of pumps, pipes and pipe fittings.

Groundwater Investigation Buntine-Marchagee Natural Diversity Recovery Catchment, Russell John Speed, M Strelein

Resource management technical reports

A groundwater investigation was initiated in the Buntine-Marchagee Natural Diversity Recovery Catchment 200 kms north-east of Perth, Western Australia in 2002. The investigation aimed to install a regional groundwater monitoring network and characterise the regolith throughout the catchment. Drill site selection was based on establishing a series of transects to enable construction of hydrogeological cross-sections to enhance conceptual understanding of the catchment.

Distribution Of North Pacific Right Whales (Eubalaena Japonica) As Shown By 19th And 20th Century Whaling Catch And Sighting Records, Phillip J. Clapham, Caroline Good, Sara E. Quinn, Randall R. Reeves, James E. Scarff, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

North Pacific right whales (Eubalaena japonica) were extensively exploited in the 19th century, and their recovery was further retarded (severely so in the eastern population) by illegal Soviet catches in the 20th century, primarily in the 1960s. Monthly plots of right whale sightings and catches from both the 19th and 20th centuries are provided, using data summarized by Scarff (1991, from the whale charts of Matthew Fontaine Maury) and Brownell et al. (2001), respectively. Right whales had an extensive offshore distribution in the 19th century, and were common in areas (such as the Gulf of Alaska and Sea …

A Self-Calibrating Palmer Drought Severity Index, Nathan Wells, Steve Goddard, Michael Hayes

School of Natural Resources: Faculty Publications

The Palmer Drought Severity Index (PDSI) has been used for more than 30 years to quantify the long-term drought conditions for a given location and time. However, a common critique of the PDSI is that the behavior of the index at various locations is inconsistent, making spatial comparisons of PDSI values difficult, if not meaningless.

A self-calibrating Palmer Drought Severity Index (SC-PDSI) is presented and evaluated. The SC-PDSI automatically calibrates the behavior of the index at any location by replacing empirical constants in the index computation with dynamically calculated values. An evaluation of the SC-PDSI at 761 sites within Nebraska, …

Human Rights, Health And The Environment, David Gillespie

Human Rights & Human Welfare

Environmental health and human rights are inextricably linked. According to the Universal Declaration of Human Rights, Article 3, “Everyone has the right to life, liberty, and security of person.” Given that the earth is the source of the basic necessities of human life, any discussion about health and human rights must be attentive to its inherent environmental aspects. International conventions, documents and reports such as Agenda 21 (1992) and The Draft Declaration of Human Rights and the Environment (1994) have expressly argued for such an integrated approach. In response, a plethora of works over the past decade have expanded the …

Modeling Corrosion In Oxygen Controlled Lbe Systems With Coupling Of Chemical Kinetics And Hydrodynamics, Samir Moujaes, Yitung Chen

Transmutation Sciences Materials (TRP)

The corrosion of structural materials is a major concern for the use of lead-bismuth eutectic (LBE) systems for nuclear applications such as in transmuter targets or fast reactors. Corrosion in liquid metal systems can occur through various processes, including, for example, dissolution, formation of inter-metallic compounds at the interface, and penetration of liquid metal along grain boundaries. Predicting the rate of these processes depends on numerous system operational factors: temperature, system geometry, thermal gradients, solid and liquid compositions, and velocity of the liquid metal, to name a few. Corrosion, along with mechanical and/or hydraulic factors, often contributes to component failure. …

Developing A Sensing System For The Measurement Of Oxygen Concentration In Liquid Pb-Bi Eutectic, Yingtao Jiang, Bingmei Fu, Woosoon Yim

Transmutation Sciences Materials (TRP)

Lead-bismuth eutectic (LBE) is a candidate as a spallation target in sub-critical transmutation systems and as a coolant in nuclear programs. One of the primary concerns with LBE systems is the corrosion of stainless steel, the primary structural material used in nuclear systems. To mitigate this problem, trace levels of oxygen can be introduced into the system, causing the formation of a protective oxide layer at the interface between the LBE and steel. To protect the steel components, this oxide layer must be properly maintained. However, too much oxygen will produce unwanted oxide precipitation within the coolant and elsewhere in …

Modeling And Measuring The Dispersion Of Odors From Hog Confinements, François Béra

Dissertations and Theses @ UNI

A comparison was made between predicted and measured odor concentration downwind of two hog finishing confinements. Two Gaussian dispersion models, STINK.BAK and AERMOD, were used. The experimental cases examined odor emanating from a mechanically-ventilated facility and a curtain-sided facility during summer 2003. A field olfactometer was used to measure odor concentration. The odor concentrations served as input to STINK.BAK, which then estimated the odor emission rate from the confinement. AERMOD used this emission rate and other meteorological data to predict the peak concentration of odor around the confinement over the sampling hour. The calculated odor emission rates are slightly higher …

Abundance Of Blue And Humpback Whales In The Eastern North Pacific Estimated By Capture-Recapture And Line-Transect Methods, John Calambokidis, Jay Barlow

United States Department of Commerce: Staff Publications

We estimated humpback and blue whale abundance from 1991 to 1997 off the west coast of the US. and Mexico comparing capture-recapture models based on photographically identified animals and line-transect methods from ship-based surveys. During photo-identification research we obtained 4,2 12 identifications of 824 humpback whales and 2,403 identifications of 908 blue whales primarily through non-systematic small-boat surveys along the coast of California, Oregon, and Washington. Line-transect surveys from NOAA ships in 1991, 1993, and 1996 covered approximately 39,000 km along the coast of Baja California, California, Oregon, and Washington out to 555 km from shore. The nearshore and clumped …

A Comparison Of Aviris And Landsat For Land Use Classification At The Urban Fringe, Rutherford V. Platt, Alexander F.H. Goetz

Environmental Studies Faculty Publications

In this study we tested whether AVIRIS data allowed for improved land use classification over synthetic Landsat ETM+ data for a location on the urban-rural fringe of Colorado. After processing the AVIRIS image and creating a synthetic Landsat image, we used standard classification and post-classification procedures to compare the data sources for land use mapping. We found that, for this location, AVIRIS holds modest, but real, advantages over Landsat for the classification of heterogeneous and vegetated land uses. Furthermore, this advantage comes almost entirely from the large number of sensor spectral bands rather than the high Signal-to-Noise Ratio (SNR).

Comparative Analysis Between Different Flood Assessment Technologies In Hazus-Mh, Jennifer Carol Meyer

LSU Master's Theses

Natural disasters devastate the United States through both economic loss and loss of life. The world wide economic damage that results from natural disasters has more than tripled in the last thirty years. Of these natural disasters, floods are the most chronic and costly disasters, comprising an average $5 billion dollars of damage each year. FEMA has released a new software program called HAZUS-MH, which attempts to capture economic losses caused by flooding before losses occur and predict losses from real-time events. This estimate is accomplished through the coupling of flood hazard modeling with local data. FEMA’s goal is that …

An Examination Of The Relationship Between Environmental Science And Law Due To Emerging Micro-Scale Gas Chromatography Technology, Alfred Ruks Politzer

LSU Master's Theses

The intersection of science and law is very complex. The two disciplines frequently interact due to environmental issues. Expert testimony is most often the method used to introduce scientific data into the legal system. Advances in technology have allowed scientists to increase the preciseness and reliability of data produced. The development of the gas chromatograph and the recent microFAST gas chromatograph has greatly increased the amounts of data available to the legal system. The legal system has relatively recently developed a set of guidelines with which to evaluate scientific evidence and determine whether it should be admitted into trial. Previously …

Regional-Scale Eutrophication Models: A Bayesian Treed Model Approach, Angelina Freeman

LSU Master's Theses

Utilizing Bayesian hierarchical techniques, regional-scale eutrophication models were developed for use in the Total Maximum Daily Load (TMDL) process. The Bayesian tree-based (BTREED) approach allows association of multiple environmental stressors with biological responses, and quantification of uncertainty sources in the water quality model. Simple parametric models are often inadequate for describing complex datasets; the BTREED approach partitions the dataset, and describes the localized subsets of data with linear models, thereby providing a comprehensive representation of stressor and response interactions. Nutrient criteria data for lakes, ponds and reservoirs across the United States were obtained from the Environmental Protection Agency (U.S. EPA) …

Feasibility Of Localized Management To Control White-Tailed Deer In Forest Regeneration Areas, Tyler A. Campbell, Benjamin R. Laseter, W. Mark Ford, Karl V. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

The deleterious effects of white-tailed deer (Odocoileus virginianus) on forest regeneration are well documented in many forested systems, but potential solutions to these problems on remote landholdings are limited in number and scope. Localized management proposes that a persistent area (<2 km2) of low density can be created by removing all individuals within matriarchal social groups of white-tailed deer. Our objective was to assess the feasibility of using localized management as a tool within forest regeneration areas. We present a comparison of seasonal home-range and core-area size and site fidelity of 148 radiomonitored female white-tailed deer in a forested landscape of the central Appalachians of West Virginia. We also characterized seasonal movements and dispersal. Adult female winter home-range size exceeded those of summer and autumn. Female deer displayed high fidelity, with home-range and core-area overlap being less in autumn than in summer or winter. Dispersal occurred in 1 of 28 (3.6%) female fawns and no deer >1 year old dispersed. Female white-tailed deer on our study site meet the a priori assumptions of localized management. We assert that experimental manipulations based on localized management concepts are prudent.

Properties Of Borate-Treated Strandboard Bonded With Pmdi Resin, Yiqiang Zhou

LSU Master's Theses

Random strandboards from mixed southern wood species were manufactured using calcium borate (CB) and zinc borate (ZB) as chemical additives and polymeric methylene diphenylmethane disocyanate (pMDI) as resin. There were four target levels of borate loading and two levels of resin content. Panel properties, including modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB) strength, linear expansion (LE), thickness swelling (TS), leachability, and swelling and strength retention properties under cyclic relative humidity, were measured. The influence of borate content, borate type, and resin content on various properties was analyzed. It was found that the addition of borate negatively …

Estimation Of Primary Production And Carbon Flux In Antarctic Coastal Waters: A Modeling Study, Hae-Cheol Kim

OES Theses and Dissertations

This study presents results from models that are designed to simulate the underwater light field, to simulate phytoplankton primary production, and to estimate the fate of phytoplankton carbon in continental shelf waters of the west Antarctic Peninsula (WAP) and Ross Sea. Simulation of the underwater light field required derivation of new coefficient sets for power function-type cloud cover correction algorithms, which were found to be influenced by multiple reflections between the bottom of clouds and the surface. The coefficient sets indicate that the spectral effect of clouds on the properties of the surface irradiance was spectrally-neutral for wavelengths greater than …

Estimating The Impact Of State Policy Incentives On Wind Power Development, Kellie K. Phelan

Honors Theses

Wind power has recently become a viable alternative to conventional fossil fuels for electricity generation because of decreasing costs and the presence of various supportive policy incentives. Pressing environmental issues and concerns about energy security have also prompted interest in wind power as an alternative fuel source. Though less than one percent of the United States electricity supply currently comes from wind power, state policy incentives have the potential to promote the development of the significant wind resources found throughout the United States (American Wind Energy Association 2003). Using a large data set that combines information on installed wind capacity …
