Kinematics and Dynamics of a Model Eastern-boundary Poleward Undercurrent

Creator:: Duran, Rodrigo
Abstract:: A carefully calibrated primitive-equation model from 41°N to 48°N is used to study the poleward undercurrent off the US west coast. Chapter 2 describes poleward flow over the slope from Eulerian and Lagrangian perspectives. The model is robust, in the sense of several characteristics being qualitatively consistent with observational and...

Optics, structure and variability of the offshore Columbia River plume

Creator:: Saldías, Gonzalo
Abstract:: The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...

Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

Creator:: Pasmans, Ivo
Abstract:: Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...

An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

Creator:: Cuzzone, Joshua K.
Abstract:: The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

Novel Copper and Iron Complexes along the Oregon Coastal Upwelling Margin

Creator:: Bright, Peter, W.
Abstract:: Copper and iron are essential micronutrients that are required by marine primary producers for a variety of metabolic processes. Over 99% of both copper and iron are bound within organic complexes in the marine environment, however the molecular identity of many of these complexes remains unknown. The speciation of these...

Intraseasonal Oscillations of ~20 days Revisited: The Jet Stream and its Ecological Implications along the Oregon Coast

Creator:: Herweck, Kendra
Abstract:: Intraseasonal oscillations in the atmosphere-ocean system can affect weather patterns and regional ecosystems. In turn, these oscillations can be affected by climate variability, resulting in additive and/or non-linear responses of regional ecosystems to climate forcing. In the Northern California Current, a strong correlation was identified between the location of the...

Investigating rotating microelectrodes for rapid in situ detection of oxygen

Creator:: Chace, Peter J.
Abstract:: Rotating disc electrodes (RDEs) exploit the induced flushing of a radially spun electrode to increase the overall rate of analyte flux to an electrode sensing surface and its resulting signal current (i). Here initial efforts to evaluate a rotating platinum (Pt) microelectrode for efficacy as a rapid in situ dissolved...

Transport and Mixing of Buoyant Water from Small Mountainous Rivers : An Investigation of Estuarine Residence Timescales and Coastal Current Propagation

Creator:: Lemagie, Emily P.
Abstract:: Small rivers, such as those that line the Oregon coast, have been shown to deliver significant concentrations of suspended sediments and nutrients to estuaries and the coastal ocean during wet seasons during which winds are predominantly downwelling-favorable. The fate of the buoyant source water and of any suspended or dissolved...

Ocean Acidification Impacts on Bivalves at Multiple Organizational Levels: From Individual Larvae to Bivalve Aggregations Habitats

Creator:: Gimenez Calvo, Iria
Abstract:: Many marine bivalves are sensitive to ocean acidification (OA) stress and often show heightened sensitivity during brief early larval and post-larval life stages, potentially leading to population bottlenecks. Most of the evidence to date has been collected in laboratory experiments that focused on physiological responses at the organismal level under...

Hydrodynamic and Morphologic Controls on Extreme Coastal Total Water Levels Across Regional and Local Scales

Creator:: Serafin, Katherine A.
Abstract:: Coastal and estuarine flooding and erosion events are usually driven by the cumulative effect of multiple individual processes like waves, streamflow, storm surge, and/or tides. This dissertation focuses on separating the influence of the regional and local-scale geomorphologic and hydrodynamic processes driving variability in the magnitude and impacts of extreme...
