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...

Quantitative Metatranscriptomics and Biogeochemical Rate Measurements Reveal Microbial Pathways Driving Carbon and Nitrogen Cycles in an Arctic Lagoon

Creator:: Griffin, Natasha A.
Abstract:: Microbial communities in Arctic coastal lagoons drive biogeochemical cycles at the terrestrial-marine interface and help to determine the fate and form of resources like nitrogen (N) and carbon (C) as they are delivered to the Arctic Ocean. Though rising rates of primary production in the Arctic Ocean are well-characterized, the...

Impact of Igneous Mineralogy on the Composition and Metabolic Function of Microbial Biofilms in a Thermal Suboceanic Crustal Aquifer

Creator:: Smith, Amy R.
Abstract:: Igneous oceanic crust encompasses ~60% of Earth’s surface and is composed of basalt glass and mafic, ultramafic, and felsic minerals. A vast marine aquifer lies within the crust, exchanging geochemically altered fluids with seawater from the overlying ocean at ridge crests, flanks, seamounts, and outcrops where permeable crust is exposed....

River Microbiome Composition Reflects Macroscale Climatic and Geomorphic Differences in Headwater Streams

Creator:: URycki, Dawn R., Good, Stephen P., Crump, Byron C., Chadwick, Jessica, and Jones, Gerrad D.
Abstract:: Maintaining the quality and quantity of water resources in light of complex changes in climate, human land use, and ecosystem composition requires detailed understanding of ecohydrologic function within catchments, yet monitoring relevant upstream characteristics can be challenging. In this study, we investigate how variability in riverine microbial communities can be...

Illuminating Patterns in Dark Microbial Matter: Diversity and Distribution of Fungi and Actinobacteria in Deep-sea Methane Seep Sediments

Creator:: Ardor Bellucci, Lila
Abstract:: Fungi and Actinobacteria are essential actors in global biogeochemical cycles of carbon and nutrients, and have both been recently appreciated for their roles in marine ecosystems. However, the diversity and distribution of these ubiquitous, but low-abundance microbes in deep-sea habitats remains poorly understood, particularly in chemosynthetic habitats such as methane...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

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,...

Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:: Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.
Abstract:: Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

New Foraminifera-Based Proxies to Trace Changes to the Organic and Inorganic Carbon System Since the Last Glacial Maximum

Creator:: Fritz-Endres, Theresa
Abstract:: The production of carbon and export to deep ocean sediments is linked to carbon partitioning between the ocean and atmosphere and is a key driver of climate change over the glacial-interglacial transition. Yet conflicting reconstructions create barriers to understanding changes to the carbon system over this important climate transition. Production...

Power and Participation in Ocean Governance Processes: A Case of the Proposed Chumash Heritage National Marine Sanctuary

Creator:: Knipp, Abigail
Abstract:: Marine protected areas (MPAs) are an area-based tool used to manage and protect areas along the coasts and ocean that face impacts from development and climate change. Local communities both impact and are affected by the creation of MPAs and as such, it is important to include their knowledge and...
