Assessing the Impact of Fishery Bait on Spatiotemporal Variation in the Feeding Ecology of Dungeness Crab (Cancer magister) Using Stable Isotopes, Gut Content Analysis & Fishermen Interviews

Creator:: Harbison, Toby N.
Abstract:: The commercial Dungeness crab (Cancer magister) fishery is Oregon’s largest trap-based fishery. Each year, crab vessels discard millions of pounds of bait, including squid, razor clams, and sardines, into the near-coastal ocean. Although the fishery season typically runs from December 1st through August 14th, most landings occur within the first...

Characterization of ecosystem structure and function recovery within the NOAA MOC-P mitigation basin, Newport, Oregon

Creator:: Lewis, Nate S.
Abstract:: Seagrass ecosystems are considered some of the most productive coastal habitats in the world. One such seagrass within estuaries of the Pacific Northwest, Zostera marina (eelgrass), is recognized to be an ecosystem engineering species that provides many important ecosystem functions and services. In 2010, construction of the National Oceanic and...

Eyes on the Seafloor : Using Video Tools to Monitor Benthic Communities at Dredged Material Disposal Sites at the Mouth of the Columbia River

Creator:: Fields, Stephanie A.
Abstract:: The mouth of the Columbia River (MCR) is an intersection of more than a river and ocean, but also multiple economically valuable activities including dredging to maintain a deep draft shipping channel and an active Dungeness crab (Metacarcinus magister) fishery. More than three million cubic meters of sediment are annually...

The Effects of Artificial Structures on Estuarine Infaunal Communities and Offshore Biofouling Communities

Creator:: Mendoza, Maritza
Abstract:: For hundreds of years, coastal and marine ecosystems have experienced increasing threats due to the cumulative effects of increasing population growth and dependence on these ecosystems. Thus, there has been increased enthusiasm to mitigate the negative effects of human actions through the use of cleaner sources of energy, like marine...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

A Bayesian approach to habitat suitability prediction

Creator:: Lockett, Daniel Edwin, IV
Abstract:: For the west coast of North America, from northern California to southern Washington, a habitat suitability prediction framework was developed to support wave energy device siting. Concern that wave energy devices may impact the seafloor and benthos has renewed research interest in the distribution of marine benthic invertebrates and factors...

The development and evaluation of an interactive exhibit to support real-time water quality data interpretation by the public at an informal education setting

Creator:: Mikulak, Sarah E.
Abstract:: Ocean observing groups are currently making efforts to work with well-defined end-user groups, like boaters and fishermen, to provide meaningful and effective real-time data (RTD) products and visualizations. However, providing meaningful data products for undefined groups such as the general public is not straightforward. In Oregon, several industry, science, and...

Oregon's Fishing Community Adapting to Change in Policy, Management, and Markets : Documenting Women's Roles and Adaptive Capacity in an Evolving Industry

Creator:: Calhoun, Sarah M.
Abstract:: Commercial fishing research often focuses on ecological (gear, stock assessment, traceability) or economic factors. Truly understanding the social-ecological system requires considering the entire "human dimension" and this includes the social, cultural, and legal/policy aspects as well. An understudied yet important factor is women's contribution to fishing at the family and...

Habitat suitability and uncertainty : a Bayesian approach to mapping benthic invertebrate distributions

Creator:: Havron, Andrea M.
Abstract:: Mitigating for increased human impact to the seafloor associated with resource extraction activities and renewable energy development can benefit from an understanding of the distribution of sensitive marine benthic species. Habitat suitability predictive modeling is a cost effective statistical tool to infer species distribution patterns from constrained sampling locations. However,...

Development from a Distance: Exploring International Non-profit Interactions with Communities during the COVID-19 Pandemic

Creator:: Peiffer, Ashley K.
Abstract:: The COVID-19 pandemic impacted the international development sector through various external and internal stressors. Community engagement practices that international non-governmental organizations and non-profits conducted were disrupted by the pandemic, and communities were faced additional challenges when international development workers were required to socially distance or relocate at the onset of...
