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...

Population dynamics, annual food consumption, movements, and dive behaviors of harbor seals, Phoca vitulina richardis, in Oregon

Creator:: Harvey, James T. (James Thomas)
Abstract:: Number of harbor seals, counted on 32 haul-out areas in Oregon, increased by 6 - 8.8 % per year from 1975 - 1983. Percent of seals in bays has increased an average 1.8%/year, from 47% in 1975 to 61% in 1983. Along the central Oregon coast, harbor seals were most...

Studies of juvenile salmonids off the Oregon and Washington coast, 1981

Creator:: Wakefield, W. Waldo, 1951-, Fisher, Jeffrey P., and Pearcy, William G.
Abstract:: The Oregon State University School of oceanography conducted purse seining surveys of juvenile salmonids in the ocean off Oregon and Washington during spring and summer 1981. The objectives of the field study were: 1) To collect information on the distribution and abundance of juvenile salmonids off Oregon and Washington; and...

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...

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...
