Methane sources, fluid flow, and diagenesis along the northern Cascadia Margin; using authigenic carbonates and pore waters to link modern fluid flow to the past

Creator:: Joseph, Craig E.
Abstract:: Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...

Application of transport-reaction modeling to constrain biogeochemical processes in marine sediments

Creator:: Hong, Wei-Li
Abstract:: Quantifying the mass transport through marine sediments, and the geochemical response to such flow with numerical models has become a common and powerful approach for geochemical data interpretation. In this dissertation, I developed and applied transport-reaction models to unravel complex and interdependent reactions involving carbon, sulfur and silica transformations in...

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

A study of whale watching visitor's cognitive constructs in relation to a whale watching outreach program : An assessment of past experience, value orientations, awareness of actions, and conceptual knowledge structure

Creator:: Christensen, Alicia H.
Abstract:: Given the current state of our oceans, the Pew Oceans Commission (1993) has strongly recommended that increased efforts be made towards ocean literacy. Informal education and outreach programs like the Whale Watching Spoken Here program are important contributors to life-long learning. However, there is little research looking at how these...

Deconvolving the sedimentary phases of barium using flow-through time-resolved analysis

Creator:: Hsieh, Chih-Ting
Abstract:: The distribution of barite (BaSO₄) in marine sediments has long been studied as a proxy for paleoproductivity. While pure barite is known to be a stable mineral in oxic sediments, it is also known that variations in the Sr/Ba ratio influence its solubility and liability during early diagenesis. To extract...

Reconstructing salinity conditions in Nares Strait (Canadian Archipelago) from stable isotope profiles in bivalve shells

Creator:: Zima, Daniela
Abstract:: Nares Strait is one of three main passages of the Canadian Archipelago that channels freshwater from the Arctic Ocean to the North Atlantic. There are very few observations regarding the role of this region on the present day Arctic freshwater budget, and even less regarding the changes in freshwater fluxes...

Contribution of cold seep barite to the barium geochemical budget of a marginal basin

Creator:: McQuay, Erica L.
Abstract:: Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...

Exploring Latinx Transfer Students' Experiences at a 4-Year University

Creator:: Rodriguez, Eduardo B.
Abstract:: The number of Latinx students enrolling in higher education has grown significantly over the past two decades (Jabbar et al., 2019). This study explores a portion of that population by focusing on the experiences of Latinx transfer students at a 4-year institution within the Pacific Northwest of the United States....

Beyond the Benthos: The effects of stream restoration on habitat complexity and aquatic and riparian macroinvertebrate assemblages

Creator:: Lotz, Kelsey L.
Abstract:: Aquatic and riparian systems in the western United States have been highly modified by anthropogenic impacts since Euro-American settlement. Ecological restoration is a practice that has been widely conducted around the world to mitigate the degradation of these systems. The majority of stream restoration efforts have focused on improving in-stream...

Particulate Trace Metal Fluxes in the Western Arabian Sea and Their Links to Marine Productivity

Creator:: Flannery, Kelly M.
Abstract:: Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies (e.g., Mo, Cd). However, not much is known about what controls the cycling of these...
