Abstract:: A 5km swath-width SeaMARC I sidescan sonar survey, conducted over the zone of overlap between the southern rift zone of Axial Volcano and the northern tip of the Vance spreading segment on the Juan de Fuca Ridge (between 45°24'N and 45°50'N latitude), was analyzed to locate the present position of...

Abstract:: The thesis area is located in north-central Oregon approximately 20 km west of the town of Mitchell. The rocks exposed in the area belong to the Clarno Formation. This study supports the informal reclassification of the Clarno to Group status, composed of an Upper and Lower Clarno Formation. An angular...

Abstract:: During the Deepwater Horizon oil well blowout in the Gulf of Mexico, the application of 7 million liters of chemical dispersants aimed to stimulate microbial crude oil degradation by increasing the bioavailability of oil compounds. However, the effects of dispersants on oil biodegradation rates are debated. In laboratory experiments, we...

Creator:: Bradley, Paul W., Gervasi, Stephanie S., Hua, Jessica, Blaustein, Andrew R., and et al.
Abstract:: Contributing to the worldwide biodiversity crisis are emerging infectious diseases, which can lead to extirpations and extinctions of hosts. For example, the infectious fungal pathogen Batrachochytrium dendrobatidis (Bd) is associated with worldwide amphibian population declines and extinctions. Sensitivity to Bd varies with species, season, and life stage. However, there is...

Abstract:: Linked atmospheric and wildfire changes will complicate future management of native coldwater fishes in fire-prone landscapes, and new approaches to management that incorporate uncertainty are needed to address this challenge. We used a Bayesian network (BN) approach to evaluate population vulnerability of bull trout (Salvelinus confluentus) in the Wenatchee River...

Creator:: Mullen, Ellen Domaratius
Abstract:: The Greenhorn Mountains contain a tectonic ally disrupted ophiolite and both arc-derived and pelagic sediments. Age of major sedimentary units within and bordering the thesis area is Early Permian, based upon dates of conodonts and fusulinids from contemporaneous but allocthanous limestones. Sediments near the south boundary of the thesis area...

Abstract:: The heterogeneous reactions of benzo[a]pyrene-d₁₂ (BaP-d₁₂), benzo[k]fluoranthene-d₁₂ (BkF-d₁₂), benzo[ghi]perylene-d₁₂ (BghiP-d₁₂), dibenzo[a,i]pyrene-d₁₄ (DaiP-d₁₄), and dibenzo[a,l]pyrene (DalP) with NO₂, NO₃/N₂O₅, and OH radicals were investigated at room temperature and atmospheric pressure in an indoor Teflon chamber and novel mono NO₂-DaiP, and mono NO₂-DalP products were identified. Quartz fiber filters (QFF) were used...

Abstract:: Between 2007 and 2009, researchers from Green Point Consulting, Oregon State University, and the South Slough National Estuarine Research Reserve collected data on ecological and physical characteristics at five high-quality “least disturbed” tidal wetland sites in four Oregon estuaries. The reference sites included in this project are (1) Blind Slough...
