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....

Summary : Pacific Northwest Drought and Human Health Workshop

Creator:: Oregon Climate Change Research Institute, National Integrated Drought Information System, and University of Nebraska Medical Center
Abstract:: Drought can have substantial negative effects on human health, creating challenges for public health departments, emergency managers, and healthcare providers. For example, drought can lead to decreased water quantity and quality, increased incidence of illness or disease, increased mortality rates, and adverse mental health outcomes, especially as livelihoods are affected....

Evaluating Drivers of Iron Cycling in Oregon Continental Margin Sediments Using an Early Diagenetic Model

Creator:: Chan, Adrienne B.
Abstract:: Continental margin sediments have been recognized as a major source of dissolved iron to the global ocean. The focus of this study was to build an early diagenetic model that can be used to simulate iron fluxes from continental margins and thereby identify key controlling factors. The model uses the...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

Applying a Dynamic Time Warping Approach to Stratigraphic Correlation: Quaternary Magnetostratigraphy and Ediacaran–Cambrian Chemostratigraphy

Creator:: Hagen, Cedric J.
Abstract:: Magneto- and chemostratigraphic correlation underpins much of our understanding of Earth history, yet typical correlation techniques are neither quantitative nor objective. Within this dissertation, I detail my efforts to develop and apply dynamic programming-based algorithms that accomplish optimal and reproducible stratigraphic alignment. I apply these algorithms to three geologic intervals:...

Volatiles and Geochemical Fingerprinting of Plagioclase-Hosted Melt Inclusions from Mid-Ocean Ridge Lavas: Determination of Depth of Crystallization and Melt Composition in the Lower Crust

Creator:: Kotash, Alisa K.
Abstract:: The global mid-ocean ridge system is the largest magmatic system encompassing over 75% of the Earth’s total volcanism. As magmas ascend through the vertically variable oceanic crust, melts begin to crystallize and diversify and subsequently erupt at the surface. The interpretation of these erupted products observed on the seafloor requires...

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,...

Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:: Nomura, Keiko
Abstract:: Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...

Wind-current Interactions of the Sri Lanka Dome and Tropical Indian Ocean

Creator:: Cullen, Kerstin
Abstract:: The southwest monsoon, which may be idealized as the northward movement of the intertropical convergence zone in the Indian Ocean associated with differential heating of land and ocean, brings a seasonal reversal of currents and winds in the Bay of Bengal and the Arabian Sea. Atmospheric convection from monsoon activity...
