Patterns of benthic macroinvertebrate communities and habitat associations in temperate continental shelf waters of the Pacific Northwest

Creator:: Lee, Timothy Seung-chul
Abstract:: Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to...

Foraging behavior of the Pacific harbor seal (Phoca vitulina richardii) in the Pacific Northwest and potential impacts of coastal hypoxia on foraging efficiency

Creator:: Steingass, Sheanna M.
Abstract:: In the last decade, the California Current Large Marine Ecosystem has experienced a trend of increased severity of upwelling-driven coastal hypoxia. This thesis strove to examine the potential upper trophic level impacts of moderate and severe hypoxia in the CCLME. Initially I conducted a literature review of Pacific harbor seal...

Comparing the hydrography and copepod community structure of the continental shelf ecosystems of Washington and Oregon, USA from 1998 to 2009 : can a single transect serve as an index of ocean conditions over a broader area?

Creator:: Lamb, Jesse F.
Abstract:: Bi-weekly sampling of zooplankton and environmental parameters was conducted along a cross-shelf transect off the coast of Newport, OR, USA (44.65°N) from 1996 to present. Results have demonstrated the feasibility of using copepod community structure as an early indicator of ecosystem response to seasonal and large scale environmental changes in...

Regional scale sandbar variability : observations from the U.S. Pacific Northwest

Creator:: Di Leonardo, Diana R.
Abstract:: Understanding sandbar dynamics and variability is integral to developing a predictive capacity for nearshore flows, sediment transport, morphological change, and ultimately for determining coastline exposure to damaging storm waves. Along the high-energy U.S. Pacific Northwest (PNW) coast, sandbars typically dominate the bathymetry of the active zone. Here we report on...

Toward establishing the validity of the transformative optimism construct measurement for tsunami preparedness : a structural equation model for visitors of the Pacific Northwest coast

Creator:: Ríos-Uribe, Carlos Andrés
Abstract:: Measurements of social constructs that evaluate natural hazard preparedness are important to decrease natural hazard vulnerability. Preparedness reduces natural hazard impacts and human vulnerability. Investment in education and education research contribute to human sustainable development and natural hazard preparedness. Faced with other needs, people typically do not prepare enough to...

Nearshore wave predictions along the Oregon and southwest Washington coast

Creator:: García-Medina, Gabriel
Abstract:: This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

Eelgrass-macroalgae interactions; context-dependency in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot
Abstract:: This dissertation investigates the context-dependency of species interactions between seagrass and macroalgae in upwelling-influenced estuaries. In all coastal systems, nutrient loading is multidirectional, resulting from mostly freshwater and marine inputs. The directionality of nutrient inputs may affect the rate of supply of organic matter to the system. In systems where...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...
