Advancing Understanding of Changes in the Cryosphere of the Western United States and Alaska: A Case for the Importance of Spatial and Temporal Scaling

Creator:: Roberts-Pierel, Benjamin M.
Abstract:: The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...

Fighting and Foliage: Land System Dynamics in the Colombian Andes-Amazon region

Creator:: Murillo-Sandoval, Paulo J.
Abstract:: In the Colombian Amazon there has been a complex interplay of rebel groups’ control over land, drug trafficking, and absence of the Government of Colombia. Here, I use satellite remote sensing, ethnographic research and statistical models to provide insights into causal effect and causal mechanisms of land change and economic...

Mining Landsat Time-series Imagery to Understand Spatiotemporal Dynamics of the Urban Landscape: A Perspective from Local Climate Zone Mapping

Creator:: Xu, Chunxue
Abstract:: We live on an Urban Planet. The current unprecedented urbanization is accompanied by intensive land cover transition and demographic shifts from rural to urban livelihoods. Cities serve as cultural, economic, political centers that facilitate wealth creation and innovation of the society, sustaining human from multi-dimensions with large ecological footprints far...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

Creator:: Lovejoy, Steven C.
Abstract:: A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

Investigating the effects of temperature on secondary metabolism in Vitis vinifera L. cv. merlot berries

Creator:: Cohen, Seth D.
Abstract:: Grapes (e.g. Vitis vinifera L.) are one of the more important fruit crops from an economic standpoint with world market values over 550 million US dollars in 2007 and 2008, second to apples (United States Department of Agriculture). While a satisfactory level of ripeness is of primary concern, the quality...

Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

A study of cavitation instabilities in solids

Creator:: Puttapitukporn, Tumrong
Abstract:: Cavitation instabilities in elastic-plastic solids under spherically-symmetric and axisymmetric loadings were investigated using the finite element method. Both quasi-static and dynamic analyses were used to solve these problems. In the quasi-static analyses, we investigated a cavitation instability in elastic/perfectly-plastic, linear hardening elastic-plastic, power hardening elasticplastic, and constrained silver materials. Here,...

Penumbra : A Spatiotemporal Shade-Irradiance Analysis Tool with External Model Integration for Landscape Assessment, Habitat Enhancement, and Water Quality Improvement

Creator:: Halama, Jonathan James
Abstract:: Several solar energy models exist, but all models must balance: computational runtime, light complexity, and model output volume. These models span the spectrum of simplistic global solar energy equation sets to complex light ray-tracing models. Spatiotemporally inaccurate representations of solar energy may cause compounding simulation effects and introduce unknown modeling...

Mapping disturbance interactions from earth and space : insect effects on tree mortality, fuels, and wildfires across forests of the Pacific Northwest

Creator:: Meigs, Garrett W.
Abstract:: Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...
