Kinetics of plankton respiration across gradient of anoxic to oxic conditions

Creator:: Jayawickrama, Clare
Abstract:: Ocean deoxygenation is predicted to increase in severity over the next few decades, posing a threat to marine life and fishing economies. Improved predictions of ocean deoxygenation depend on a better understanding of the biogeochemical mechanisms that underly this process. Within the realm of biogeochemical mechanisms, this project specifically investigated...

Metabolomic Analysis of Oregon Coast Sediment Pore Waters using Ultrahigh Resolution Mass Spectrometry

Creator:: Merlo, James B.
Abstract:: One of the principal drivers of climate change is the concentration of greenhouse gases such as CO2 in the atmosphere. A large portion of this CO2 ends up in the waters off the continental coasts where it transforms into biomass. The major sink for this matter is the ocean sediments...

Using Stable Isotopes to Quantify Ecological Interaction Strengths

Creator:: Shepard, Isaac D.
Abstract:: Understanding ecological interaction strengths is one of the main objectives of ecology. Recently, two methods for estimating interaction strengths of predator-prey interactions in nature have been proposed: a field observation approach proposed by Novak and Wootton (2008) and stable isotope analysis. The field observation method estimates feeding rates based on...

Contributions of photoautotrophy and heterotrophy to the carbon and nitrogen nutrition of Anthopleura elegantissima in three symbiotic states

Creator:: Hampton-Wonder, Kathryn Anne
Abstract:: The Pacific coast sea anemone Anthopleura elegantissima is an excellent model organism for the study of temperate symbiosis due to its unique relationship with two microalgal symbionts, Elliptochloris marina and Symbiodinium spp. In addition to hosting one or both of these symbionts, A. elegantissima can live aposymbiotically, allowing for the...

Astragalus peckii Population Establishment : Developing Protocols for Seed Germination, Seedling Cultivation, and Planting

Creator:: Pearson, Tabitha
Abstract:: Astragalus peckii Piper is a threatened Oregon endemic in the pea family (Fabaceae). This species faces extinction due to loss of habitat. Recovery efforts include augmenting existing populations and creating new ones. The purpose of this study was to determine the best methodology for population augmentation of Astragalus peckii by...

The Secret Life of Estuaries: Phytoplankton-determined Seasonality of Particulate Organic Carbon in Cathlamet Bay and the Columbia River Estuary

Creator:: Shumway, David O.
Abstract:: This study investigated the composition and character of organic matter on suspended particulate material (SPM) in the Columbia River estuary system to determine the contribution of biological activity in lateral bays to the greater nutrient cycle of the river. Water samples were collected during neap and spring tidal forcing (25...

A Geochemical Model for the Petrogenesis of the Curaçao Lava Formation: Implications for the Origin of the Caribbean Plateau

Creator:: Krawl, Kyle A.
Abstract:: The Curaçao Lava Formation (CLF) records the magmatic and tectonic processes that formed the Caribbean Large Igneous Province (CLIP). A model of the petrogenesis of the CLF was developed using new geochemical and geochronological data. These data include major element compositions obtained using X-ray fluorescence spectroscopy (XRF), trace element concentrations...

Analysis and Modeling of Kinetic Parameters for Urea Hydrolysis by Bacteria for Use in Calcium Carbonate Precipitation in Aquifers

Creator:: Neighbor, Christopher J.
Abstract:: The use of ureolytic bacteria for the remediation of contaminated groundwater aquifers by inducing calcium carbonate precipitation is being studied in order to establish a better understanding of the modeling and prediction of how the bacteria will act in situ. This research has pursued the use of various ureolytic bacteria...

Using An Array of NE Pacific Margin Sediment Samples to Link Land and Ocean Responses to Glacial-Interglacial Climate Variability

Creator:: Wilson, Kiya L.
Abstract:: Variability in the terrigenous (land-derived) fraction of marine sediments, including pollen and rock fragments, reflects the effects of regional climate change on continentally derived runoff, ice extent, vegetation and ocean circulation. The transport of this continental material to the seafloor must be understood in order to interpret the terrigenous sediment...

The potential influence of database configuration on the derivation of trace element partitioning expressions for clinopyroxene

Creator:: Cunningham, Jennifer L.
Abstract:: Decades of experimental work has illustrated the high degree to which the partitioning of most elements is dependent on phase composition, temperature and pressure. In order to quantitatively describe clinopyroxene partitioning it is required to derive expressions using theoretical constraints calibrated with experimental data. The experimental database available for such...
