A Spatial Assessment of Conservation Opportunities in the Willamette River Floodplain between Corvallis and Albany, Oregon

Creator:: Baker, Jeffrey M.
Abstract:: The Willamette River floodplain has been highly modified by urbanization, conversion of land to agriculture, construction of dams and revetments, and regulation of flow, all of which have reduced floodplain processes that provide valuable ecosystem services such as fish and wildlife habitat and flood storage. Efforts to protect and restore...

A GIS Evaluation of Land Use Zones and Water Quality for Marine Conservation Site Selection in Lincoln County, Oregon

Creator:: Henderson, Ann Miller
Abstract:: The leasing of submerged and submersible lands is emerging as a new marine conservation method. Using a geographic information system, this study: (1) examines the suitability of estuary tideland sites for conservation leasing in Lincoln County, Oregon, and (2) explores the relationship between adjacent terrestrial land use zones and the...

Coastal hazards and community exposure in a changing climate : the development of probabilistic coastal change hazard zones

Creator:: Baron, Heather M.
Abstract:: Documented trends in rising sea levels, storminess, and extreme wave heights have the potential to increase the frequency and magnitude of coastal change hazards, increasing risks to coastal infrastructure and environmental resources. Coastal planners and decision makers need information about the impacts of future hazards in order to apply mitigation...

Exotic plant species dynamics from 1994 to 2005 on road networks in forested landscapes of western Oregon

Creator:: Sheehy, Samantha
Abstract:: Although the Pacific Northwest has the least proportion of non-native plant species in relation to other regions of North America, exotic species continue to spread into mountainous areas, including the Cascade Range. In a forested landscape, road networks can act as corridors for exotic plant dispersal and establishment, helping species...

Lava Flow Lobation and Margin Analysis

Creator:: Peckyno, Robert S.
Abstract:: Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...

Geographic distributions of prey of the northern spotted owl in the central western Cascades, Oregon, 1988-2009

Creator:: Smoluk, Alexis
Abstract:: Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This study describes the spatial variation in owl diet based on 4183 prey collected at 114 owl...

The distribution of geologic and artifact obsidian from the Silver Lake/Sycan Marsh geochemical source group, South-Central Oregon

Creator:: Thatcher, Jennifer J.
Abstract:: Geochemical characterization methods are commonly used in the reconstruction of prehistoric raw material use and procurement systems. Trace element studies of lithic source material and artifacts, specifically those made of obsidian, can reveal important information about the environmental and cultural factors which influence the prehistoric distribution of raw material. The...

Spatial analysis of soil depth variability and pedogenesis along toposequences in the Troodos Mountains, Cyprus

Creator:: Robins, Colin R.
Abstract:: In unstable landscapes, modern pedological research explores the role of soils as products and indicators of geomorphologic change. Understanding the dynamics of hill slope pedogenesis is especially important in regions with limited, poor, or threatened soil resources. The island of Cyprus, situated in the eastern Mediterranean, is claimed by many...

A recurrent neural network implementation using the graphics processing unit

Creator:: Moore, Christopher
Abstract:: We took the back-propagation algorithms of Werbos for recurrent and feed-forward neural networks and implemented them on machines with graphics processing units (GPU). The parallelism of these units gave our implementations a 10 to 100 fold increase in speed. For nets with less than 20 neurons the machine performed faster...

Comparison of MODIS binary and fractional snow cover mapping techniques in the Himalayan Region, Nepal

Creator:: Tuladhar, Preeti
Abstract:: Satellite remote sensing is an effective tool for mapping snow covered area. However, complex terrain and heterogeneous land cover, due to vegetation and patchy snow cover, present challenges to snow cover mapping. This research compares two techniques for mapping snow covered area: binary and enhanced fractional snow cover mapping techniques....
