Bioeconomic Simulation Modeling of Fisheries : Three Essays

Creator:: Cusack, Christopher Inju
Abstract:: Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...

Re‐establishment of the native oyster, Ostrea conchaphila, in Netarts Bay, Oregon, USA

Creator:: Archer, Pamela Emily
Abstract:: Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...

The Role of Iron: How Natural and Human-Induced Iron Fertilization Could Change Ocean Productivity

Creator:: Adroli, Nurmalia
Abstract:: Iron (Fe) is an important limiting nutrient that can affect the rate of ocean primary production because it is required by phytoplankton as an enzymatic cofactor in photosynthesis, nitrogen fixation, and other essential metabolic functions. Most Fe reaches the surface of the open ocean via atmospheric dust deposition, which is...

Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

Offshore Wind Energy's Role in the United States' Energy Transition

Creator:: Erdesz, Krisa (Muller)
Abstract:: As the human population grows, the need for alternative and clean forms of energy is greater. The installation of offshore wind energy has been on the rise over the past decade, however the fossil fuel energy generation sectors, such as coal and natural gas, are still major players in the...

Development of an autonomous in-situ instrument for long-term monitoring of Cu(II) in the marine environment

Creator:: Holm, Christopher E.
Abstract:: An autonomous, in-situ instrument was developed to detect dissolved copper in seawater, suitable for deployment on time scales from weeks to months. A commercially available in-situ nitrate analyzer (YSI 9600) was adapted to measure copper (II) in seawater by chemiluminescence. Modifications included construction of a photomultiplier (PMT) based detector and...

Investigation of polycyclic aromatic hydrocarbons (PAHs) transport by suspended particulate matter (SPM) in the lower Columbia River and its estuary

Creator:: Gregg, Tiffany
Abstract:: This study aims to improve knowledge of how suspended particulate matter (SPM) affects hydrophobic contaminant transport in the lower Columbia River and its estuary, using polycyclic aromatic hydrocarbons (PAHs) as model compounds. It is hypothesized that PAHs are transported to the estuarine turbidity maximum (ETM), a prime feeding zone in...

Habitat Associations and Diet Composition of Western Purple Martins in Western Oregon

Creator:: Sherman, Lorelle M.
Abstract:: The western purple martin (Progne subis arboricola) is a species of conservation concern throughout the Pacific Northwest. In western Oregon, the purple martin nests in three major ecosystem types: inland open-water, coastal, and upland forest. The availability of suitable breeding habitat is a major limiting factor for western purple martin...

Larval Biogeography and Varying Spawning Behavior of Bering Sea Groundfishes: Implications for Management in a Changing Seascape

Creator:: Vary, Laura
Abstract:: Early life stages of marine fishes exert substantial control on the productivity and resilience of marine fisheries, as these life stages represent periods of extreme mortality. Additionally, eggs and larvae of marine fishes respond rapidly to environmental change and can thus be used to infer ecosystem-wide responses to climate change...

Encounter norms of snorkelers and scuba divers at Molokini, Hawai'i : methodological and managerial applications

Creator:: Bell, Caitlin M.
Abstract:: Over the past few decades, tourism and recreation activities have increased in tropical marine settings, and studies have examined social and ecological impacts of these activities. Some studies have examined social impacts such as encounters, crowding, and encounter norms or standards that individuals use to evaluate encounters with others as...
