A study on the effects of enhanced pCO2 on open ocean diazotrophic assemblages

Creator:: Gradoville, Mary Rose
Abstract:: Biological di-nitrogen (N₂) fixation is a key process in open-ocean ecosystems, where the new nitrogen (N) provided by marine diazotrophs can support a large fraction of primary productivity and carbon (C) drawdown. Recent laboratory studies have shown that elevated pCO₂ enhances the rate of N₂ fixation by select laboratory isolates...

Pacific Coast Groundfish Fishery Assessment and Management: Incorporating Nearshore Surveys into the Fishery Management Framework

Creator:: Haven, Katlyn M. M.
Abstract:: The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

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...

Southern Ocean Science and Society: Case Studies at the Nexus of Research, Education, and Policy

Creator:: Hann, Ashley M.
Abstract:: Even in remote environments, human and natural systems are connected. Pressing environmental and social changes warrant the field of science to not only continue to enhance understanding of the natural world, but also consider the socio-ecological implications of research in the coupled human-natural system. Additionally, a need exists for communication...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

Macroalgae Decrease Growth and Alter Microbial Community Structure of the Reef-Building Coral, Porites astreoides

Creator:: Thurber, Rebecca Vega, Burkepile, Deron E., Correa, Adrienne M. S., Thurber, Andrew R., Shantz, Andrew A., Welsh, Rory, Pritchard, Catharine, and Rosales, Stephanie
Abstract:: With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the coral microbiome, which is thought to play...

Of Mysid and Menidia: Sublethal Effects of Micro and Nanoplastics on Estuarine Indicator Species

Creator:: Dickens, John
Abstract:: Microplastics are widely distributed in aquatic environments. The term ‘microplastics’ encompasses a wide array of particles with unique polymer constituents, morphologies, and sources, such as automobile tire tread. Tire wear particles (TWP) can end up in waterways near densely populated municipalities, where they can interact with aquatic biota. Studying the...

Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:: Adams, Katherine A.
Abstract:: Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...
