Novel Copper and Iron Complexes along the Oregon Coastal Upwelling Margin

Creator:: Bright, Peter, W.
Abstract:: Copper and iron are essential micronutrients that are required by marine primary producers for a variety of metabolic processes. Over 99% of both copper and iron are bound within organic complexes in the marine environment, however the molecular identity of many of these complexes remains unknown. The speciation of these...

Evaluating Drivers of Iron Cycling in Oregon Continental Margin Sediments Using an Early Diagenetic Model

Creator:: Chan, Adrienne B.
Abstract:: Continental margin sediments have been recognized as a major source of dissolved iron to the global ocean. The focus of this study was to build an early diagenetic model that can be used to simulate iron fluxes from continental margins and thereby identify key controlling factors. The model uses the...

Sediment Deposition Characteristics in Shallow Saturation Excess Overland Flow with Application to Bioswales and Construction of a Novel Bioswale Design for Improved Contaminant Removal from Stormwater

Creator:: Wells, Jacqueline R.
Abstract:: Over the last two decades, urban stormwater management has grown to include green infrastructure, such as bioswales. These systems were primarily designed to mitigate hydraulic peaking during rainstorms but were also found to remove particulate and dissolved contaminants. However, little is known about the fate of these particulate contaminants after...

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...

Effects of Secondary Salinization on Three Coastal Breeding Amphibians in Oregon: Taricha granulosa, Hyliola regilla, and Rana aurora

Creator:: Goddard, Amanda L.
Abstract:: Due to threats of secondary salinization caused by increased saltwater intrusion upstream associated with climate change, this thesis examines how salinity affects the development and oviposition site selection habits of three Oregon coastal breeding amphibians, the Roughskin Newt (Taricha granulosa), the Northern Red-legged Frog (Rana aurora) and the Pacific Treefrog...

Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

Creator:: Herrmann, Joan F.
Abstract:: Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

Fishing for Hypoxia: Exploring Coastal Oxygen Dynamics and Predictability of Low Oxygen Episodes through a Partnership with the Oregon Dungeness Crab Fishing Fleet

Creator:: Stoltz, Linus O.
Abstract:: Coastal hypoxia, or low oxygen episodes pose a threat to marine resources in the Pacific Northwest. Previous research into nearshore oxygen dynamics have linked coastal upwelling to this seasonally occurring phenomenon, however the manifestation of hypoxic waters over coastal fishing grounds was not well understood. Through a partnership with Dungeness...

The Influence of Model Resolution on Dispersal and Retention in Oregon Coastal Waters

Creator:: Wong-Ala, Jennifer A. T. K.
Abstract:: Lagrangian particle tracking (LPT) models are used to explore how physical processes influence the transport of particles (e.g., eggs, larvae, or propagules) in the ocean. On the Oregon continental shelf and slope, the Northern California Current System (CCS) is influenced by spatially and temporally variable coastal currents driven by weather,...

Physical Modeling of the Feedbacks Between a Reed Canarygrass (Phalaris arundinacea) Patch, Hydraulics, and Bedform Evolution

Creator:: Elliott, Susan H.
Abstract:: Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...

Morphology, Sediment Microbial Analysis, and Species Distribution Modeling of a New Offshore Population of Ghost Shrimp (Neotrypaea sp.)

Creator:: Hardisty, Sarah
Abstract:: In 2019, a multi-cohort population of the typically estuarine burrowing shrimp Neotrypaea sp., was discovered approximately 7 miles offshore of Newport, Oregon. Morphological analysis of the offshore population, microbial sediment sequencing, and species distribution modeling was conducted with this new offshore population. In order to identify Neotrypaea sp. to the...
