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...

Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:: Boisen, Olivia C.
Abstract:: It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

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...

Juvenile Pacific Oyster Growth and Food Resources in Eelgrass Habitats of Variable Shoot Density in Tillamook Bay, OR: Ecosystem Interactions for Management Consideration

Creator:: Merrill, Julianne
Abstract:: As the global demand for seafood increases each year, there is a growing need to expand sustainable aquaculture in the interests of food security and resilience of coastal communities. Pacific oysters, Crassostrea gigas, are grown in West coast estuaries - where cultures often overlap with the federally protected native eelgrass,...

The Environmental, Economic, and Social Factors that Contribute to the Importance of the Pacific Razor Clam (Siliqua patula) Fishery for Oregon Coastal Communities: A Northern Oregon Case Study

Creator:: Baker, Laura C.
Abstract:: Pacific razor clams (Siliqua patula) are narrow oblong bivalves that can be found in sandy habitats along the western coast of the United States, from Alaska (Aleutian Islands) to southern California (Pismo Beach). In Washington state, the razor clam fishery has been documented to be an important contributor to the...

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...

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...

High-resolution Carbonate Dynamics of Netarts Bay, OR from 2014 - 2019

Creator:: Fairchild, William M.
Abstract:: Netarts Bay is a shallow, temperate, tidal lagoon located on the northern coast of Oregon and site of the Whiskey Creek Shellfish Hatchery (WCSH). Data collected with an automated flow-through system installed at WCSH capable of high-resolution (1 Hz) pCO2 and hourly TCO2 measurements, with measurement uncertainties of <2.0% and...

Genetic Connectivity of Dungeness Crab (Cancer magister) in the California Current System and Puget Sound

Creator:: Jackson, Tyler M.
Abstract:: Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...

Development of satellite bloom detection products for coastal Oregon

Creator:: McKibben, S. Morgaine
Abstract:: Two bloom-detection products were developed for the Oregon coast that describe the relative percent change observed between successive pairs of 8-day chlorophyll-a (CHL) and fluorescence line-height (FLH) products obtained from the MODerate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft (MODIS-Aqua). The CHL[subscript dev] and FLH[subscript dev] products, respectively, were optimized...
