Distribution and origin of organic matter preserved in modern surface sediments throughout Coastal SE Alaska

Creator:: Walinsky, Sarah E.
Abstract:: Twenty seven modern (top 1-2cm) sediment samples from multicores retrieved from throughout coastal SE Alaska were analyzed for their organic matter content and the source composition. Total organic carbon (TOC) as well as biogenic silica (bioSi), and calcium carbonate (CaCO3) content were analyzed to evaluate the organic matter content and...

An Investigation of Ceratomyxa shasta sporulation following death of itsChinook salmon host

Creator:: Soderlund, Krista M.
Abstract:: As pre-spawning mortality (PSM) in Chinook salmon in the Willamette River Valley becomes a more defined and examined area of study, more focus is granted to not only preserving the health of these fish, but also expanding knowledge concerning various pathogens that utilize the salmon as hosts and may be...

Sensitive Barnacles : A Case Study for Collaborative Sustainable Fishery Development

Creator:: Bingham, Julia
Abstract:: Current human – ocean relationships are dominated by unsustainable extraction of marine resources having both ecological and socio-economic consequences. Sustainable fishery management utilizing stakeholder collaboration must become a proactive strategy to prevent or reduce further long-lasting impacts. In Oregon, USA, a newly developing fishery for gooseneck barnacle (Pollicipes polymerus) presents...

A proposed method to analyze meso- and microplastic pollution on beaches in Oregon

Creator:: Losh, Sage
Abstract:: Meso- and microplastic debris is becoming a rising coastal issue as more research highlighting the detrimental impacts this material has on marine organisms and the environment is performed. This research, however, continues to be conducted in a non-standardized manner meaning that the data being collected cannot be compared spatially or...

Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

Creator:: Young, Thomas
Abstract:: Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

An evaluation of the establishment and continued effectiveness of the Galápagos National Park and Marine Reserve in Ecuador

Creator:: Asson, Danielle
Abstract:: Conservation of natural resources has become a new watchword of the scientific community. While many terrestrial ecosystems are well protected, marine ecosystems have only recently come to the forefront. Marine Protected Areas (MPAs) have been introduced as a means of protecting biodiversity, commercial stocks, and ecosystem services. There are many...

Evaluating the mixed species feeding opportunities provided by foraging humpback whales (Megaptera novaeangliae) across ocean ecosystems

Creator:: Ellett, Lindsey G.
Abstract:: Group foraging occurs across many ecosystems and taxa, and benefits some or all individuals in the group by optimizing feeding efficiency. The beater theory describes when individual “beaters” benefit other group members by herding prey into more accessible areas. Humpback whales feed on a variety of small patchy prey, and...

Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

Creator:: Stewart, Anna
Abstract:: The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...
