Mantle melting and heterogeneity along mid-ocean ridges : insight from basalt geochemistry along axial depth and morphologic gradients for intermediate spreading rate systems

Creator:: Russo, Christopher J.
Abstract:: This investigation focuses on gaining a better understanding of the complex relationship between melt generation, source variability and mid-ocean ridge morphology. The approach adopted here uses a variety of geochemical techniques to evaluate the ability of 'global' models to predict regional scale geochemical variability associated with axial depth and axial...

Control of alkane monooxygenase activity and expression in Pseudomonas butanovora

Creator:: Doughty, David M.
Abstract:: The regulation of monooxygenase enzymes has been demonstrated in bacteria that grow on methane and long chain-length alkanes (>C10). Less is known about monooxygenase regulation in short chain alkane oxidizing bacteria that grow on intermediate chain-length alkanes C2-C10. This dissertation focuses on the regulation of butane monooxygenase (BMO) expression and...

A geospatial data catalog and metadata management tools for the U.S. Environmental Protection Agency’s Western Ecology Division

Creator:: Bradford, David L.
Abstract:: The EPA’s Western Ecology Division (WED) had been accumulating geographic information system (GIS) data files for up to 20 years. There was no index or catalog for these files; locating data became more difficult over time. More that 4 Tb of data existed on numerous disk volumes in hundreds of...

Brant use of Yaquina Estuary, Lincoln County, Oregon in the spring of 1976

Creator:: Wetzel, David J.
Abstract:: Black Brant (Branta bernicla nigricans) distribution was monitored and eelgrass beds (Zostera marina) were mapped during the spring migration of 1976. Brant used eelgrass areas significantly, and human disturbance and tide height were important factors influencing Brant distribution and activity.

Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

Creator:: Yarger, David J.
Abstract:: Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

Identifying potential wetland restoration sites for estuary-wide restoration planning in Oregon : A pilot project in the Coos Estuary

Creator:: Fuss, J. David
Abstract:: Oregon's estuaries have been significantly altered by human activity, so that many former tidal wetlands no longer provide the functions, such as fish and wildlife habitat, erosion protection from storms, and water quality maintenance, that preserve the integrity of estuarine ecosystems. Oregon has been a leader in wetland protection and...

Measure 37 report and recommendations to Sen. Floyd J. Prozanski, Jr., Rep. Gregory H. Macpherson, Co-Chairs, Joint Special Committee on Land Use Fairness, 2007 Legislative Session

Creator:: Atiyeh, Victor, Roberts, Barbara, 1936-, and Gray, John D. (John Delton), 1919-
Abstract:: In summary, as detailed below in Section III, we recommend the 2007 Legislature put Measure 37 back on the track of fair and honest compensation for all claimants, and corral the threat to Willamette Valley agriculture at the same time, by providing as follows: • Whether in the form of...

The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:: Boyle, Stephanie A.
Abstract:: The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

Variation in communities of ammonia-oxidizing and denitrifying bacteria in Fennoscandian boreal forest soils

Creator:: Ghimire, Rama D.
Abstract:: The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...

Geochemical and helium isotopic variability within the Lau Basin

Creator:: Goddard, Charlotte Ives
Abstract:: This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...
