Effects of Hypoxia on Survival and Growth of Barnacle Larvae Off the Oregon Coast

Creator:: Amstutz, Amanda C.
Abstract:: In recent years off the United States Oregon coast severe hypoxic events have resulted in areas of mass vertebrate and invertebrate species mortality known as dead zones. Creation of dead zones and alteration of community species composition in response to inner shelf hypoxic conditions have been observed annually from 2002...

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...

Patterns of macrophyte wrack deposition on sandy beaches of the Pacific Northwest coast, U.S.A.

Creator:: Reimer, Jessica N.
Abstract:: Dislodged macroalgae and seagrasses, also known as marine wrack, frequently wash into coastal ecosystems from the ocean and are potentially important ecological resources for biological communities. These!nutrient and organic matter subsidies may be especially important on sandy beaches, where little in situ primary productivity exists for higher trophic levels. To...

Full Text:: insight and guidance on my project. Dr. Francis Chan encouraged me to think critically about my research

Impacts of Ocean Acidification on Coralline Algae : From Species to Community Consequences

Creator:: Shen, Chenchen
Abstract:: Oceanic uptake of rising anthropogenic CO₂ emissions has caused the emergence of ocean acidification as a major threat to marine ecosystems worldwide. Along eastern boundary current systems, seawater is naturally acidified due to coastal upwelling of low pH seawater from depth. Compounded by ocean acidification, upwelling regions are expected to...

Full Text:: interest in my intellectual development. My talks with Francis Chan have had a disproportionate impact

Marine Mass Mortality in a Global Change Context: Impacts on Individuals, Populations and Communities

Creator:: Sullivan Stack, Jenna
Abstract:: Human actions are pushing natural systems into states that have no historical precedent. In response, empirical and theoretical researchers are increasingly focused on developing ways to predict the responses of ecological systems to change. However, significant knowledge gaps remain, often leading to “ecological surprises” where observed impacts of global change...

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...

Coastal Dunes as Meta-Ecosystems: Connecting Marine Subsidies to Dune Ecosystem Functions on the U.S. Pacific Northwest Coast

Creator:: Constant, Vanessa
Abstract:: Ecological communities are connected in space and time through the transfer of energy, materials, and organisms, together known as ecological subsidies. These ecological subsidies can have substantial effects on community structure, function, and services, especially when the connections are between communities with contrasting productivity. At the ocean-land interface, low productivity...

Plankton food web dynamics and larval fish success : influence of prey and predator distributions on larval fish diet, growth, and assemblages in the Straits of Florida

Creator:: Gleiber, Miram R.
Abstract:: Survival of marine fishes during their early life history stage is tightly related to prey availability and predation pressure. Yet, our understanding of how individual larvae to entire assemblages are constrained by these factors is limited. We integrated biological sampling of larval fishes with fine-scale in situ imaging to relate...

Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

Creator:: Koch, Jack C.
Abstract:: Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

Adaptive Potential of Coastal Invertebrates to Environmental Stressors and Climate Change

Creator:: Burton, Andrea R.
Abstract:: Climate change presents multiple stressors that are impacting marine life. As carbon dioxide emissions continue to increase in the atmosphere, atmospheric and sea water temperatures increase. In addition, more carbon dioxide is absorbed into the oceans, reducing pH and aragonite saturation state, resulting in ocean acidification (OA). Tightly coupled with...
