Quantifying Sensitivity and Adaptive Capacity of Shellfish in the Northern California Current Ecosystem to Increasing Prevalence of Ocean Acidification and Hypoxia

Creator:: Gossner, Hannah M.
Abstract:: The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...

Professional Development Training in Ocean Acidification: A Case Study of Marine Resource Managers

Creator:: Moses, Michael L.
Abstract:: Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...

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...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

Creator:: Sousa, Francis J. and Sousa, Daniel J.
Abstract:: Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...

Exploring perceptions and experiences of the U.S. West Coast shellfish industry dealing with ocean acidification

Creator:: Mabardy, Rebecca Anne
Abstract:: Nearshore and estuarine environments along the U.S West Coast are ocean acidification (OA) "hotspots". Carbon dioxide-enriched water has been correlated with production losses of Pacific oyster (Crassostrea gigas) larvae at hatcheries in the Pacific Northwest. Limited and unreliable supply of larval seed has implications for the economic well-being of commercial...

North Atlantic Climate and Cryosphere Variability Over the Past 20,000 Years

Creator:: Sinclair, Gaylen
Abstract:: Reconstructing the sensitivity of past climate to forcings, and of ancient glaciers and ice sheets to this climate, can allow us to better understand the range of climate and cryosphere behavior we may see in the coming centuries. The Arctic is a region of particular importance due to its well-documented...

Subducting Seamounts and Heceta Bank: An Amphibious Seismic Tomography Experiment of the Central Oregon Forearc

Creator:: Nolan, Sarah
Abstract:: Studies reveal differences in slip segmentation and plate coupling along the Cascadia subduction zone. The segment between 44.0°N and 45.0°N exhibited reduced slip in the 1700 megathrust earthquake (Wang et al., 2013) and corresponds with previous rupture boundaries inferred from paleoseismic data (Leonard et al., 2010). Notably, this segment of...

Detection of Physical and Biological Fronts in the Northern California Current System and the Drivers Behind Their Seasonal to Interannual Variability

Creator:: Jamil, Aliya L.
Abstract:: Oceanic fronts mark the boundary between two water masses and are often sites of complex bio-physical processes and multi-trophic level interactions, making them particularly important features in marine ecosystems. As global climate change induces multi-scale shifts in the driving physical mechanisms of fronts, spatiotemporal tracking of frontal variability can aid...

Marine Neritic and Epipelagic Community Dynamics: An Investigation of the 'Yin' and 'Yang', No-Analog, and Refugia from a Multi-species Perspective

Creator:: Barceló, Caren
Abstract:: Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...
