Spatiotemporal dynamics and drivers of stream pCO₂ in a headwater mountain catchment in the Cascade Mountains, Oregon

Creator:: Dosch, Nicholas T.
Abstract:: We examined the spatial and temporal variability of stream carbon dioxide (CO₂) and the drivers of these variations in a headwater catchment. To examine temporal variation and drivers, we measured stream and hyporheic pCO₂ at high temporal resolution over 11 months in a 95.9-ha forested headwater catchment in the Western...

Regional Scale Modeling of Climate, Cryosphere, and Freshwater Discharge in Changing Coastal Mountain Environments

Creator:: Beamer, Jordan P.
Abstract:: The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...

Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

Creator:: La Nier, Justin
Abstract:: Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

Scaling of Hyporheic Exchange Processes and Finding the Intermediate Sweet Spot

Creator:: Becker, Paige Sheridan
Abstract:: Hyporheic zones are important regions that reside below and along the sides of streams. Within this region, several ecosystem services are provided including stream temperature regulation, habitats for a large variety of species, pollutant removal, and nutrient cycling. Exchange between the hyporheic zone and stream occurs across multiple scales, but...

Hydrological and biogeochemical dynamics of nitrate production and removal at the stream – ground water interface

Creator:: Zarnetske, Jay P.
Abstract:: The feedbacks between hydrology and biogeochemical cycling of nitrogen (N) are of critical importance to global bioavailable N budgets. Human activities are dramatically increasing the amount of bioavailable N in the biosphere, which is causing increasingly frequent and severe impacts on ecosystems and human welfare. Streams are important features in...

Innovative Coaching in Intercollegiate Athletics : Advocating for Cultural Responsiveness

Creator:: Thompson, Mitchell D.
Abstract:: It has been established that intercollegiate sport is an important social institution for student athletes of color in the United States (Coakley, 2012). White intercollegiate coaches have a prominent influence on the academic, athletic, social and emotional development of student athletes and therefore must be tuned into variation in cultural...

An econometric analysis of output supply and input demand in the Oregon softwood lumber and plywood industries

Creator:: Guerrero Ochoa, Isabel G.
Abstract:: The present study employs a normalized restricted quadratic profit function approach to estimate lumber and plywood supply and Marshallian factor demand elasticities for four region-product combinations in Oregon for the period 1970-2010. The four log demand functions will be employed as the "demand side" of the log market model of...

An analysis of the viability of ranked set sample methodologies based on the evaluation of Dyess AFB B-47 crash site radiological contamination survey data and theoretical modifications

Creator:: Miller, Vivien J.
Abstract:: Since Ranked Set Sampling (RSS) was proposed in 1952 by G.A. McIntyre, it has been the subject of many statistical investigations and a large number of field studies. Throughout these studies RSS has been proven to provide a better estimate of population the mean and variance than Simple Random Sampling...

Empirical Analyses of Forestry Interactions with Climate Uncertainty and Threatened Species

Creator:: Johnson, Kelsey K.
Abstract:: Forests are highly valuable resources providing both timber as well as many non-use values like habitat for various endangered and threatened species, carbon sequestration, and recreation, to name a few. Given that there are 765 million acres of forestland in the United States, almost 60% of which are privately owned,...

Turn-Taking in Face-to-Face Conversations: A Proposed Theory of Chair Swiveling

Creator:: Smith, Lyshuand R.
Abstract:: The purpose of this thesis is to propose swiveling behavior as a potential speech transitioning device and to discuss the methodology behind qualitative and quantitative analysis of swivels in relation to subjects’ partners. Due to the impacts of gaze and body orientation direction on speech transitioning, it is deduced that,...
