Crustal inheritance and a top-down control on arc magmatism at Mount St. Helens

Creator:: Bedrosian, Paul A., Peacock, Jared R., Bowles-Martinez, Esteban, Schultz, Adam, and Hill, Graham
Abstract:: In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington...

Youth Recruitment and an Aging Workforce : A Pilot Study of Intergenerational Family Business in Oregon’s Commercial Fishing Industry

Creator:: Caracciolo, Deanna E.
Abstract:: Commercial fishing is a culturally and economically significant industry on the Oregon coast. The importance of this industry to human communities is often neglected in fisheries research, with economic and ecological data being favored by managers and decision makers. Recent observations in many coastal communities have indicated aging of fishermen...

Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

Pillaging Bloodwood: An Exploratory Examination of Illegal Deforestation in Guinea-Bissau Through Forest Disturbance Algorithms and Unsupervised Clustering Techniques

Creator:: Walters, Alexander E.
Abstract:: Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...

Shell Boring Polychaetes and the Oregon Oyster Aquaculture Industry: Spatial Distribution, Regulatory Actions, and Stakeholder Engagement

Creator:: Considine, Megan E.
Abstract:: Shell-boring polychaetes pose economic risks for oyster aquaculture industries as they reduce the aesthetic quality of oyster products by creating unsightly mud-filled blisters on the inside of the shell. Recently there has been a reported uptick in infested oysters on commercial farms along the west coast of the US, which...

Spatiotemporal Variability in Benthic-Pelagic Coupling on the Oregon-Washington Shelf: An Investigation of Bottom Water and Benthic Flux Data

Creator:: Hughes, Anna R.
Abstract:: Continental shelf sediments are sinks for dissolved oxygen and sources of many major and minor nutrients required for oceanic surface primary production, resulting in a strong coupling between benthic and pelagic biogeochemical cycling. However, the influence and spatiotemporal variability of benthic remineralization on bottom-water chemistry and the supply of nutrients...

Introducing and validating a high-throughput bud break sensor

Creator:: Kleinknecht, George J.
Abstract:: Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:: Moore, Nicole E.
Abstract:: Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

The Effects of the Flow Regime on Stream Channel Form and Processes

Creator:: Hempel, Laura A.
Abstract:: Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...
