A wireless power transfer system using inductive coupling was designed and implemented as part of a three-member project team. The system uses coupled magnetic fields at a frequency of 606kHz to transfer electromagnetic energy from a charging base to the batteries of portable devices. It succeeded in transmitting power to...
Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...
Body size is known to correlate with many aspects of life history in birds, and this knowledge can be used to manage and conserve bird species. However, few studies have compared the wintering ecology of sympatric subspecies that vary significantly in body size. We used radiotelemetry to examine the relationship...
Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...
Information on winter marine bird and mammal distributions in Oregon coastal waters has been identified as a data need for marine spatial planning of ocean energy development. As part of the annual marine mammal surveys of the critical habitat for Endangered Species Act (ESA)-listed Southern Resident Killer Whales (Orcinus orca),...
Concise information on the basics of managing livestock in winter, including use of sound production practices. Particularly for the region east of the Cascade Mountains. Companion audio files describe:
audio4: Winter Livestock Care. How to keep your animals healthy in inclement weather, through shelter, feeding, and water access.
audio5: All...
Diets of juvenile coho Oncorhynchus kisutch and Chinook O. tshawytscha salmon
are made up primarily of winter-spawning fish taxa in the late-larval and early juvenile stages that
are undersampled in plankton and larger trawl nets. Although we have no direct measure of the
availability of fish prey important to juvenile...
As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes...
Wine grape pomace (WGP) as a source of antioxidant dietary fiber (ADF) was fortified in yogurt (Y), Italian (I) and Thousand Island (T) salad dressings. During the three weeks of storage at 4 °C, viscosity and pH of WGP-Y increased and decreased, respectively, but syneresis and lactic acid percentage of...
This thesis is a report of a phenomenological-informed study of public university student spiritual development. The research was based primarily upon semi-structured personal interviews and a focus group with undergraduate students at a large, public research institution on the west coast. Since the introduction of scientific objectivity into the academy...
Across-shelf transects over the eastern flank of Barrow Canyon were obtained in August 2005 with an autonomous underwater vehicle (AUV). Here, the shelf topography creates a “choke” point in which a substantial portion of Pacific inflow from the Bering Strait is concentrated within 30 km of the coast, providing an...
The Chukchi Sea is thought to be a globally important sink of atmospheric CO₂ due to the summertime drawdown of surface pCO₂ by phytoplankton and subsequent shelf-to-basin transport of CO₂-enriched subsurface waters into the upper halocline of the Arctic Ocean. Here we show that annually occurring storm-induced mixing events during...
The surface wind and stress responses to sea surface temperature (SST) are examined using collocated moored buoy and satellite observations in the Gulf Stream and the eastern equatorial Pacific. Using 17 buoy pairs, differences in the wind speed, 10-m equivalent neutral wind speed (ENW), and surface wind stress magnitude between...
The number of wind turbines and wind farms in the Pacific Northwest has increased dramatically in the past six years, which represents a significant amount of electrical generation capacity connected to the public electric grid. However, the variable nature of wind sometimes introduces excessive power, or conversely shortages, in power...
The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...
Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...
Increasing renewable energy development is often seen as an essential tool for combating global climate change, yet despite widespread support in theory, renewable energy often faces problems at the implementation stage. In the state of Washington, where voters have expressed a desire for greater renewable energy by mandating that 15%...
Concerns over climate change and energy security have spurred governments worldwide to encourage the development of renewable energy. Although public attitudes and macro-politics, in general, show moderate to strong support for renewables- in particular, wind power- largely because of the economic and environmental benefits associated with it. However, local politics...
While the U.S. energy portfolio increasingly includes renewables, social acceptance of such technologies can pose an important challenge for developers. Using survey data from a random sample of nearby households (n=524), content analysis of coverage in local newspapers, and interviews with various stakeholders (n=14), I explore local social acceptance of...
Wind energy has widespread public support; nevertheless, the emergence of local support or
opposition in response to siting proposals is often unpredictable. Uncertainty surrounding a
community’s response is problematic for both the company planning the project and for states
pursuing policies for expanded development and use of renewable energy. Given...
The authors investigate atmospheric internal gravity waves (IGWs): their generation and induction of global intermittent turbulence in the nocturnal stable atmospheric boundary layer based on the new concept of turbulence generation discussed in a prior paper by Sun et al. The IGWs are generated by air lifted by convergence forced...

Regulatory requirements and shifts in consumer preferences have resulted in seafood products bearing multiple information labels. Developing successful seafood marketing strategies requires an understanding of how multilabeled products influence consumer choices. This paper analyzes preferences for four classes of seafood information labels including safety, quality, local, and ecolabels using data...
This study examines the willingness of canoe owners and crew members to participate in an insurance scheme in Ghana. A total of 386 canoe owners and 164 crew from four (4) coastal regions and the inland lake areas were sampled. Data was collected through semi-structured questionnaires on socio-economic characteristics, canoe...
This project examines two understudied female characters from Geoffrey Chaucer’s Canterbury Tales who emerge as subversive figures by striving to maintain control over their bodies and being. Through my analyses of the Knight’s and Second Nun’s Tales, I reveal how virginity correlates with bodily autonomy for the narratives’ respective protagonists,...
The Forest Elevation Snow Transect (ForEST) project is a paired site elevational snow study. It is designed to measure how snow accumulates and ablates under different forest structures across an elevation range. The ForEST project has been ongoing since the winter of 2011-2012 within the McKenzie River Basin of the...
The SLICES framework is intended for use in making decisions about conservation and restoration in the Willamette River floodplain. It makes use of distinct spatial units, called slices, for planning and tracking change in the floodplain. The Floodplain Forest ca. 2010 Technical Report identifies data sources, describes the data processing,...
