A New Record of Planktic Foraminifera Community Response to Marine Heatwaves in the Northeast Pacific

Creator:: M. Kelsey Lane
Abstract:: Marine heat waves are forecasted to increase in frequency and intensity under future climate scenarios, but little is known about the impact of these events on the one of the most commonly used proxies of ocean temperature - foraminiferal assemblages. This research explores the planktic foraminifera community along the Newport...

Dose of reality : what can we learn from educational and veterinary pet owners to guide more effective environmental stewardship of pharmaceutical and personal care products (PPCPs)?

Creator:: Lam, Jennifer
Abstract:: Improper disposal of unused human and pet pharmaceuticals and personal care products (PPCPs) are an emerging public and watershed health threat around the world. Although some waste stream reduction programs such as PPCPs "take-back" exist, there is limited research in current programs on reducing the entry of PPCPs into the...

The Influence of Model Resolution on Dispersal and Retention in Oregon Coastal Waters

Creator:: Wong-Ala, Jennifer A. T. K.
Abstract:: Lagrangian particle tracking (LPT) models are used to explore how physical processes influence the transport of particles (e.g., eggs, larvae, or propagules) in the ocean. On the Oregon continental shelf and slope, the Northern California Current System (CCS) is influenced by spatially and temporally variable coastal currents driven by weather,...

Oceanographic Drivers of Northern California Current Phytoplankton Communities and their Fatty Acid Composition: Implications for Northwest Fisheries

Creator:: Smoak, Rebecca T.
Abstract:: Micro-plankton are a crucial component of pelagic food webs, responding rapidly to environmental changes, and providing a first step in the acquisition and transfer of nutrients to life in the ocean. In addition to the uptake of carbon, phytoplankton provide essential fatty acids (FAs) that can limit the growth of...

Aquatic pesticide best management practices and relational database for the protection of NOAA trust species

Creator:: Gianou, Kelsey, Lam, Jennifer, Emanuel, Robert, Jepson, Paul, and Chan, Sam
Abstract:: Pesticides are widely used to control undesirable pests and may be applied directly to water or lands directly adjacent to water. There can be unintended consequences, however, to native, threatened, and endangered species. There is little information on the impacts of aquatic pesticides and best management practices (BMPs) to NOAA...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

Data assimilation for prediction of shallow water flows with uncertain bathymetry

Creator:: Wilson, Gregory W.
Abstract:: A new method is introduced for incorporating bathymetric uncertainty into predictions of nearshore and river flows (i.e., unstratified flows primarily forced by pressure and radiation stress gradients). The method involves the use of the ensemble Kalman filter (EnKF) as a parameter estimation scheme, where the parameter to be estimated is...

Investigating the Paleoseismic Potential of Small, Southern Cascadia Lakes

Creator:: Ross, Ann Elizabeth Morey
Abstract:: Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...

The Effects of Structure and Volcanic Stratigraphy on Groundwater and Surface Water Flow: the Hat Creek basin Case Study, California, USA

Creator:: Marcelli, Marina F.
Abstract:: Hydrogeologic systems in the southern Cascade Range develop in volcanic rocks where volcanic morphology, stratigraphy, extensional structures and attendant basin geometry play a central role in groundwater-flow paths, groundwater/surface-water interactions, and spring discharge locations. High-volume springs (> 3 m3/s) flow from young (< 1 Ma) volcanic rocks in the Hat...
