Effects of estuarine circulation patterns and stress on the migratory behavior of juvenile salmonids (Oncorhynchus sp.)

Creator:: Truelove, Nathan Kobun
Abstract:: For the first objective of this thesis, we attempt to understand the role of water flow and directionality in determining steelhead (Oncorhynchus mykiss) and spring/summer and fall Chinook (O. tschawytscha) migration patterns within the Columbia River Estuary and plume by integrating recent advances in biotelemetry and environmental observation and forecasting...

Creator:: Miller, Jessica A., Teel, David J., Peterson, William T., and Baptista, Antonio M.
Abstract:: Research on regulatory mechanisms in biological populations often focuses on environmental covariates. An integrated approach that combines environmental indices with organismal-level information can provide additional insight on regulatory mechanisms. Survival of spring/summer Snake River Chinook salmon (Oncorhynchus tshawytscha) is consistently low whereas some adjacent populations with similar life histories experience...

Disentangling bottom-up and top-down effects on survival during early ocean residence in a population of Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Miller, Jessica A., Teel, David J., Baptista, Antonio, and Morgan, Cheryl A.
Abstract:: We evaluated the relative importance of "bottom-up" (production-limited) and "top-down" (predator-mediated) processes during early marine residence in a population of Chinook salmon (Oncorhynchus tshawytscha) from the upper Columbia River, USA. We examined length, mass, and condition index of age-0 juveniles collected in the ocean during June and September across 11...

Myrionecta rubra population genetic diversity and its cryptophyte chloroplast specificity in recurrent red tides in the Columbia River estuary

Creator:: Herfort, Lydie, Peterson, Tawnya D., McCue, Lee Ann, Crump, Byron C., Prahl, Fredrick G., Baptista, Antonio M., Campbell, Victoria, Warnick, Rachel, Selby, Mikaela, Roegner, G. Curtis, and Zuber, Peter
Abstract:: For several decades, annually recurring blooms of the photosynthetic ciliate Myrionecta rubra have been observed in the Columbia River estuary in late summer. In an effort to understand the dynamics of these blooms, we investigated the genetic variability of M. rubra and its cryptophyte plastids within 3 large estuarine blooms...

Impact of parameter variability on the food process engineering calculations required for safety, quality and shelf-life estimations

Creator:: Chotyakul, Nattaporn
Abstract:: Quantitative procedures were developed to determine the effect of variability in the model parameters required for the estimation of microbial shelflife and thermal processing time. Monte Carlo simulations combined with these predictive models were implemented in Microsoft Excel™. In the first study, predictive models were used for shelf-life predictions based...

Development of an automated capacitor discharge welding system

Creator:: Patnaik, Srinivas M.
Abstract:: Automation of Capacitor Discharge Welding (CDW) has not been investigated in industry due to the limited understanding of the process. The US Department of Energy's Albany Research Center (ALRC) has done an extensive study of the process and reported applications of welds in the manufacture of electro-mechanical products such as...

Permeability properties of an edible methylcellulose-palmitic acid film

Creator:: Rico-Pena, Delmy del Carmen
Abstract:: The use of edible coatings in combination with antimicrobial agents enhances the microbial stability of foods. In this study we evaluated the potassium sorbate and sorbic acid permeability of an edible methylcellulose (MC) - palmitic acid (PA) film with a MC:PA ratio of 3:1. Permeability cell measurements were used to...

Infrastructure for collaborative science and societal applications in the Columbia River estuary

Creator:: Baptista, António M., Seaton, Charles, Wilkin, Michael P., Riseman, Sarah F., Needoba, Joseph A., Maier, David, Turner, Paul J., Kärnä, Tuomas, Lopez, Jesse E., Herfort, Lydie, Megler, V. M., McNeil, Craig, Crump, Byron C., Peterson, Tawnya D., Spitz, Yvette H., and Simon, Holly M.
Abstract:: To meet societal needs, modern estuarine science needs to be interdisciplinary and collaborative, combine discovery with hypotheses testing, and be responsive to issues facing both regional and global stakeholders. Such an approach is best conducted with the benefit of data-rich environments, where information from sensors and models is openly accessible...
