Population Dynamics and Variability of Two Gelatinous Zooplankters (Aequorea and Pyrosoma atlanticum) in the Northern California Current

Creator:: Sorensen, Hilarie L.
Abstract:: This research focused on population dynamics of two gelatinous zooplankters (Aequorea & Pyrosoma atlanticum) in the northern California Current to assess their relationship to environmental conditions and role in the pelagic ecosystem. Data collected since 1999 showed seasonal and interannual fluctuations in the abundance and distribution of Aequorea in the...

Invasive Plant Management Plan (IPM) and Digital Tools for Big Sur Land Trust of Monterey County, California

Creator:: Nichols, Abby L.
Abstract:: An Invasive Plant Management Plan developed for Big Sur Land Trust, a non-profit conservation organization located on California's Central Coast, to guide its vegetation management activities and serve as a decision-support tool. The effort included the creation of a digital field data collection tool through Survey123 Connect, survey and data...

Parameter Estimation within a Kinematic Magnetohydrodynamics Framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We discuss the well-posedness of the forward problem for the magnetohydrodynamic system with the inclusion of the ion-slip parameter. We also demonstrate the convergence of a parameter estimation scheme. Focusing on power-generation, we implement and the validate a numerical model with an engineering multi-physics software, COMSOL, using ideal-power equations. We...

Quantifying uncertainty with stochastic collocation in the kinematic magentohydrodynamic framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We discuss an efficient numerical method for the uncertain kinematic magnetohydrodynamic system. We include aleatoric uncertainty in the parameters, and then describe a stochastic collocation method to handle this randomness. Numerical demonstrations of this method are discussed. We find that the shape of the parameter distributions affect not only the...

Stochastic Collocation Error Analysis Within a Kinematic Magnetohydrodynamics Framework

Creator:: Rajbhandari, Evan, Gibson, Nathan L., and Woodside, C. Rigel
Abstract:: We explore one numerical method for dealing with uncertainty quantification, stochastic collocation. We adapt this method for the uncertain kinematic magnetohydrodynamic system. We then demonstrate well-posedness of the uncertain forward problem. We also describe the method in detail, and perform an error analysis of the method, describing the necessary assumptions...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...
