Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

The potential influence of database configuration on the derivation of trace element partitioning expressions for clinopyroxene

Creator:: Cunningham, Jennifer L.
Abstract:: Decades of experimental work has illustrated the high degree to which the partitioning of most elements is dependent on phase composition, temperature and pressure. In order to quantitatively describe clinopyroxene partitioning it is required to derive expressions using theoretical constraints calibrated with experimental data. The experimental database available for such...

Olivine and plagioclase-hosted melt inclusions and their application to determining parental arc magmas

Creator:: Kohut, Edward John
Abstract:: Three broadly interrelated problems of critical significance to the proper interpretation of melt inclusion (MI) data are addressed in this thesis. The first issue, the petrogenesis of anorthitic plagioclase phenocrysts in MORB lavas, has relevance due to the presence of numerous MI in many high-An feldspars. This problem was addressed...

Delayed upwelling alters nearshore coastal ocean ecosystems in the northern California current

Creator:: Barth, John A., Menge, Bruce A., Lubchenco, Jane, Chan, Francis, Bane, John M., Kirincich, Anthony R., McManus, Margaret A., Nielsen, Karina J., Pierce, Stephen D., and Washburn, Libe
Abstract:: Wind-driven coastal ocean upwelling supplies nutrients to the euphotic zone near the coast. Nutrients fuel the growth of phytoplankton, the base of a very productive coastal marine ecosystem [Pauly D, Christensen V (1995) Nature 374:255–257]. Because nutrient supply and phytoplankton biomass in shelf waters are highly sensitive to variation in...

The role of subduction fluids in generating compositionally diverse basalts in the Cascadia subduction zone

Creator:: Rowe, Michael C.
Abstract:: The primary goal of this study is to assess the impact of a subduction component added to the mantle wedge beneath the Oregon Cascades to the composition and fO2 of primitive Cascade basalts. Olivine-hosted melt inclusions from compositionally diverse basalts across the Cascade arc (~100 km) are utilized in an...

Analysis of the processing and characterization of p-type CuScO₂ thin films

Creator:: Nielsen, Benjamin C.
Abstract:: Two different doping techniques, oxygen intercalation and Mg cation substitution, were investigated in thin film p-type CuScO₂, a wide band gap semiconductor with the delafossite structure. Films rf-sputtered onto amorphous SiO₂ substrates were polycrystalline after post-deposition annealing. X-ray diffraction was used to determine that the films are predominantly polycrystalline 3R...

Welfare implications of EU enlargement: the case of East Baltic cod

Creator:: Nielsen, Max
Abstract:: Recent research has warned that liberalising trade in capture fishery products originating from inefficient managed fisheries might cause over-exploitation, reduced fish stocks and thereby reduced steady state welfare. This paper qualifies the warning in a case study of the East Baltic cod market by introducing a quantitative supply model of...

Utilization of natural and supplemental biofuels for harvesting energy from marine sediments

Creator:: Nielsen, Mark E.
Abstract:: A benthic microbial fuel cell (BMFC) is an electrochemical device that generates current from the redox gradient at the sediment-water interface. Early prototypes had anodes buried in anoxic sediments and cathodes in overlying water. The BMFCs described in this dissertation are based on a chamber design that enables the use...

Trade liberalisation and resource sustainability

Creator:: Nielsen, Max
Abstract:: Traditional economic theory states that liberalising trade and moving to freer trade in conventional goods improves global welfare, as well as improving welfare in small countries. It also states that large countries only through the active use of their trade policies can maximise their welfare. However, these results are modified...

Snow Peak, OR: late Miocene to early Pliocene volcanism in the central Cascadia forearc

Creator:: Hatfield, Ashley K.
Abstract:: Snow Peak is a voluminous shield volcano located ~50 km west of the axis of the modern Cascade arc. A previously published K-Ar age estimate indicates that the Snow Peak lavas are ~3 Ma. Subsequently, the preliminary research framework for studying the Snow Peak lavas focused on constraining the petrogenesis...
