Remote Sensing Of Soil Moisture In Vineyards Using Airborne And Ground-Based Thermal Inertia Data, Aiman Soliman, Richard J. Heck, Alexander Brenning, Ralph Brown, Stephen Miller

Publications and Research

Thermal remote sensing of soil moisture in vineyards is a challenge. The grass-covered soil, in addition to a standing grape canopy, create complex patterns of heating and cooling and increase the surface temperature variability between vine rows. In this study, we evaluate the strength of relationships between soil moisture, mechanical resistance and thermal inertia calculated from the drop of surface temperature during a clear sky night over a vineyard in the Niagara region. We utilized data from two sensors, an airborne thermal camera (height ≈ 500 m a.g.l.) and a handheld thermal gun (height ≈ 1 m a.g.l.), to explore …

Remote Sensing Of Green Leaf Area Index In Maize And Soybean: From Close-Range To Satellite, Anthony L. Nguy-Robertson

School of Natural Resources: Dissertations, Theses, and Student Research

This dissertation seeks to explore alternative methodologies for estimating green leaf area index (LAI) and crop developmental stages. Specifically this research [1] developed an approach for creating a Moderate Resolution Imaging Spectroradiometer (MODIS) high spatial resolution product for estimating green LAI on the base of data collected using two different close-range sensors. It was determined that the vegetation indices (VIs) Wide Dynamic Range Vegetation Index (WDRVI) and Enhanced Vegetation Index 2 (EVI2) were capable of accurate estimation of green LAI from MODIS 250 m data using models developed from hyperspectral (RMSE < 0.69 m² m^-2; CV < 33%) or multispectral sensors (RMSE < 0.69 m² m^-2; …

Reviewing Models Of Land Availability And Dynamics For Biofuel Crops In The United States And The European Union, Ruopu Li, Nicola Di Virgilio, Qingfeng Guan, Song Feng, Goetz M. Richter

School of Natural Resources: Faculty Publications

The biofuel-related land use in the USA and the EU has significantly expanded during the last decade; models have been used to estimate land availability and demand in these regions. This paper provides an overview of different land-use modeling practices applicable to first- and second-generation biofuels. We review the importance of different land categories for biofuels, modeling approaches (top-down/bottom-up) and their integration, data availability for calibration and validation, model scale, and uncertainty. Possible future changes of biofuel land use and research gaps and limitations are synthesized. Key issues are the lack of data for independent validation and the need for …

The Politics Of The "New North": Putting History And Geography At Stake In Arctic Futures, Andrew T. Stuhl

Faculty Journal Articles

References to a “New North” have snowballed across popular media in the past

10 years. By invoking the phrase, scientists, policy analysts, journalists and others

draw attention to the collision of global warming and global investment in

the Arctic today and project a variety of futures for the region and the planet.

While changes are apparent, the trope of a “New North” is not new. Discourses

that appraised unfamiliar situations at the top of the world have recurred

throughout the twentieth century. They have also accompanied attempts to

cajole, conquer, civilize, consume, conserve and capitalize upon the far north.

More Effective Human Spaceflight Programs And Their International Security Implications, Bert Chapman, Sarag J. Saikia

Libraries Faculty and Staff Scholarship and Research

NASA can more effectively perform its missions by transferring its aeronautic responsibilities to the Federal Aviation Administration and be renamed the National Space Agency. The U.S. must also recognize that space is an emerging arena of international competition and conflict and militarily protect its space assets from China which seeks to use space to restrict the U.S.' ability to defend its strategic interests in regions such as the Western Pacific.

Security Here Is Not Safe': Violence, Punishment, & Space In The Contemporary U.S. Penitentiary, Karen M. Morin

Faculty Journal Articles

The US penitentiary at Lewisburg, Pennsylvania, was retrofitted in 2008 to offer the country’s first federal Special Management Unit (SMU) program of its kind. This model SMU is designed for federal inmates from around the country identified as the most intractably troublesome, and features double-celling of inmates in tiny spaces, in 23-hour or 24-hour a day lockdown, requiring them to pass through a two-year program of readjustment. These spatial tactics, and the philosophy of punishment underlying them, contrast with the modern reform ideals upon which the prison was designed and built in 1932. The SMU represents the latest punitive phase …

The Role Of Suburbia In The Attribution Of Greenhouse Gas Emissions, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

The original goal of the research presented here was to quantify by world region, the contribution of urbanized areas to global greenhouse gas (GHG) emissions (EDGAR, 2011). Regressions on population density and growth rate, GDP, and heating/cooling degree days, as well as a row of other non-significant variables, show that the contribution of urban extents is between 38% and 49% of total emissions (Marcotullio et al., 2012). In spite of using very liberal definitions of urban extents (GRUMP, 2011) this is at the low end of academic estimates (Satterthwaite, 2008; WEO, 2008; Dhakal, 2010). It is no surprise that the …

Avalanche Chronology Of The Maple Mountain/Spanish Fork Peak Avalanche Paths, Kimball Hansen, Dr. Matthew Bekker

Journal of Undergraduate Research

I began planning my project of the avalanche chronology of the Maple Mountain/Spanish Fork Peak Avalanche Paths in 2009 while applying for the ORCA grant. I was currently wrapping up a similar project of an avalanche chronology of Loafer Mountain near Woodland Hills Peak. This later project helped form a basis for the new avalanche path near Spanish Fork Peak. Since the two paths are relatively close to each other in the Wasatch Mountain Range, I can use the chronology found from Loafer Mountain avalanche path with the new path I will be researching and correlate the data and help …

Afterward presenting, we had the opportunity to talk with other professors studying migration that were interested in our research.

Understory Diversity And Succession On Coarse Woody Debris In A Coastal, Old-Growth Forest, Oregon, Shannon Lee Mcdonald

Dissertations and Theses

This research examines the relationship between understory plant diversity and logs in a Pacific Northwest (PNW) Sitka spruce (Picea sitchensis)-western hemlock (Tsuga heterophylla) old-growth, coastal forest. These forests are renowned for their high forest productivity, frequent wind storms, and slow log decomposition rates that produce unmatched accumulations of coarse woody debris (CWD) yet few studies have examined the relationship between CWD and understory vegetation ecology. My research addressed this topic by comparing understory plant census data between paired fallen log and forest floor sites (n=20 pairs). My objectives were to: 1) determine the influence of substrate type on community composition …

Identifying Potential Wilderness Areas On The Fremont-Winema National Forest With Arcgis Modelbuilder, Zach Adams

Geography and the Environment: Graduate Student Capstones

The Fremont-Winema National Forest administers over two million acres in south central Oregon. Part of managing this landscape includes overseeing existing wilderness areas and identifying new potential wilderness areas. In the past this process has been cumbersome, with little thought given to standardizing the effort across the administrative area. This project was an effort to develop a geospatial model that incorporates U.S. Forest Service spatial datasets ultimately standardizing the potential wilderness identification process during site specific NEPA analysis.

Gis Analysis Of Placer Gold Mining Potential In The Yuba River Watershed, California, J. D. Chandler

Spacing Units In The Greater Wattenberg Area, Tera Dillon

Geography and the Environment: Graduate Student Capstones

Horizontal wells are the most commonly drilled wells in the Wattenberg Field, located in Weld County, Colorado. Petroleum engineers have become interested in determining how many horizontal wells can economically be drilled per section in this vertically, well-developed field. Using the Colorado Oil and Gas Conservation Commission’s spacing unit regulations as a guide, a GIS workflow was developed to create the deliverables required for further analysis. Spacing units were created by applying a buffer to horizontal well surveys, and using this buffer to select intersecting quarter-quarter sections. The selected quarter-quarter sections were simplified using the dissolve tool and then spatially …

Guidance In Feature Extraction To Resolve Uncertainty, Boris Kovalerchuk, Michael Kovalerchuk, Simon Streltsov, Matthew Best

Computer Science Faculty Scholarship

Automated Feature Extraction (AFE) plays a critical role in image understanding. Often the imagery analysts extract features better than AFE algorithms do, because analysts use additional information. The extraction and processing of this information can be more complex than the original AFE task, and that leads to the “complexity trap”. This can happen when the shadow from the buildings guides the extraction of buildings and roads. This work proposes an AFE algorithm to extract roads and trails by using the GMTI/GPS tracking information and older inaccurate maps of roads and trails as AFE guides.

Evaluation Of A Coupled Event-Driven Phenology And Evapotranspiration Model For Croplands In The United States Northern Great Plains, V. Kovalskyy, G. M. Henebry, D. P. Roy, B. Adusei, M. Hansen, G. Senay, D. M. Mocko

Natural Resource Management Faculty Publications

A new model coupling scheme with remote sensing data assimilation was developed for estimation of daily actual evapotranspiration (ET). The scheme consists of the VegET, a model to estimate ET from meteorological and water balance data, and an Event Driven Phenology Model (EDPM), an empirical crop specific model trained on multiple years of flux tower data transformed into six types of environmental forcings that are called “events” to emphasize their temporally discrete character, which has advantages for modeling multiple contingent influences. The EDPM in prognostic mode supplies seasonal trajectories of normalized difference vegetation index (NDVI); whereas in diagnostic mode, it …

¿Del Mar Quién Es Dueño? Artisanal Fisheries, Tourism Development, And The Struggles Over Access To Marine Resources In Playa Gigante, Nicaragua, Nikolai Alexander Alvarado

Electronic Theses and Dissertations

In post-revolutionary Nicaragua tourism development has been embraced as a way to inject foreign exchange into an ailing economy. Despite rapid growth of the sector, particularly along Nicaragua's southwestern Pacific coast, little attention has been given to the impacts of this development on local producers. This research focuses on the tourism development taking place in the fishing community of Playa Gigante and its impacts on artisanal fisheries. Additionally, I focus on the struggles over access to marine resources, especially with creation of La Anciana Marine Protected Area (MPA), a marine conservation corridor being pushed forth by the largest resort development …

Perceptions And Experiences Of Environmental Health Risks Among New Mothers: A Qualitative Study In Ontario, Canada, Eric Crighton, C Brown, Jamie Baxter, L Lemyre, J R. Masuda, F Ursitti

Geography & Environment Publications

There is a growing awareness and concern in contemporary societies about potential health impacts of environmental contaminants on children. Mothers are traditionally more involved than other family members in managing family health and household decisions and thus targeted by public health campaigns to minimise risks. However little is known about how new mothers perceive and experience environmental health risks to their children. In 2010, we undertook a parallel case study using qualitative, in-depth interviews with new mothers and focus groups with public health key informants in two Public Health Units in Ontario Province, Canada. We found that the concern about …

Alaska Winter's Relationship To Domestic Violence And Alcohol Abuse, Jennifer Marie Read

Geography and the Environment: Graduate Student Capstones

Alaska is known for its long, dark, cold winter months. Daylight savings time exists to cope with months that have little sunlight, but that still leaves on average, five hours of daylight. Special light bulbs exist to help with the darkness by providing light that tricks the body into thinking it is getting more sun than it really is. As daylight decreases, the weather turns colder; depression, alcohol, and domestic violence begin to rise. Studies show alcohol related crime and domestic violence occur more during the winter months in Alaska. This research paper will analyze the data pertaining to alcohol …

A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey

United States National Park Service: Publications

Scope of Analysis

North American bats are highly unique animals that have historically been overlooked by land managers and misunderstood by the public. Bats are unique as the only true flying mammals and due to their exceptionally long lives (5-15 years) and unusually low reproductive rates (typically one young per year) for their small size. Most North American bat species are insectivorous, serve as the primary predators of nocturnal insects, and can consume up to one-third of their weight in insects per night. Thus, bats play a role in regulating insect populations, insect-related ecological processes, and nutrient redistribution and cycling …

Change And Continuity: Euro-American And Native American Settlement Patterns In The St. Joseph River Valley, Allison M. Kohley

Masters Theses

In recent years there has been a particular interest in the fur trade and colonialism through identification and investigation of Fort St. Joseph. This fort was an 18th century French trading post in the St. Joseph River valley located in southwestern Michigan and northwestern Indiana. This study expands our current understanding of the change and continuity of the Euro- American and Native American settlement patterns in the valley during the periods immediately prior to, during, and after the abandonment of Fort St. Joseph through the use of geographic information systems (GIS) and statistical analyses.

Blm Riparian Area Management Technical Reference: Using Uas Remotes Sensing Imagery To Assess Proper Functioning Condition Of Riparian-Wetland Areas, Heather Fonda

Geography and the Environment: Graduate Student Capstones

The Bureau of Land Management (BLM) was loaned older military Unmanned Aerial Systems (UAS) and is pioneering their employment for land management applications. Riparian areas make up a small percentage of BLM lands but are some of the most environmentally and economically valuable. Assessments of these riparian areas are required by law. Assessments from UAS imagery could become an important monitoring tool that is cheaper, safer and allows access to previously unreachable areas. This capstone project tests the UAS imagery for conducting riparian proper functioning condition (PFC) and quantitative assessments; and includes a technical reference with an interpretation key and …

The Impact Of Westernization On The Fijian Birth Model, Sophia Heick

Social Sciences

Over the past 200 years a dramatic shift in the method of birth has occurred in the world and especially in the United States. Birth has been transformed from a common event overseen by a local midwife, a process that was common and largely mysterious as it lacked any scientific understanding, to an infrequent event overwhelmingly overseen by obstetricians and scientifically dissected in attempts to maximize health outcomes. Although many countries have gone through a transition similar to this, this specific transition is unique to the culture of the United States. With the impact that US Western culture is having …

Geographical Spread Of Asians In California, Lydia Tang

Social Sciences

The goal of my senior project is to perform a spatial analysis of Asian American settlement patterns within California. With my findings, I want to predict future Asian immigrant settlement patterns, places within California that they will likely cluster around, the rate of immigration, and how their increasing or decreasing presence in California affects California’s urban and economic climate. What I hope to achieve from this study is an understanding for why certain areas attract more Asians than others. By finding the answers to the following questions, I will be able to forecast the future spread of Asian Americans in …

The Effectiveness Of The New Town Policy In Managing Growth And Congestion In Mega Cities: A Case Study Of Lagos, Nigeria New Town Policy, Abolaji Samson Olanipekun

Masters Theses

One of the major challenges facing municipal governments of megacities in developing countries is shortage of urban infrastructures relative to population growth. Because cities play important role in the economic development of every nation, problems confronting them require proactive policy measures by the government. One such mega city is Lagos, Nigeria. From 1962 to 2006, the population of Lagos grew from 1,135,805 to 17.5 million. Crammed on a 2200 square kilometer land area of which 18.9%, Lagos population is projected to reach 20.5 million by 2015, an explosion largely driven by the non-regulatory internal migration system. The result of this …

Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner

Masters Theses

Three separate storage technologies able to serve gridded data were selected for comparison of performance in terms of providing speed and expandability to a crop disease forecasting system. The three storage technologies chosen were PostgreSQL (a relational database management system), MongoDB (NoSQL system), and netCDF files. Speed tests were performed for each by running two different crop disease risk forecasting models requiring data of different spatiotemporal resolutions. Multiple trials were done using different storage hardware. Systems were then qualitatively compared for expandability by noting the process involved in adding successive crop disease forecasting models.

It was found that due to …

Gis-Based Flood Analysis For Adequate Flood Mitigation In An Unplanned Urban Area; The Case Of Pikine Dagoudane In Dakar County, Senegal, Sokhna Helene Diop

Masters Theses

Since 1989, Pikine Dagoudane, in the suburbs of Dakar City has faced several flooding events, resulting in economic loss, environmental degradation and severe disturbance of the social life of the residents. The mitigation programs implemented have not appeared to provide any relief since 2000. Review of the existing literature on the crisis has revealed that the general scale of the studies, and the insufficient attention to some of the major factors could be accounted for such little efficiency. This thesis applies a different approach, based on a small area and focusing mainly on topographic characteristics, to provide a better understanding …
