Stratigraphic correlation of seismoturbidites and the integration of sediment cores with 3.5 kHz chirp subbottom data in southern Cascadia

Creator:: Black, Bran
Abstract:: In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...

Rapid equilibrium response of a marine diatom to external and internal nutrient concentrations

Creator:: Lundy, Daniel Wayne
Abstract:: Batch cultures of Skeletonema costatum were grown under continual light saturation, with nitrogen nutrients in limiting concentrations. Population parameters measured included ¹⁴C uptake, chlorophyll a, particulate carbon and nitrogen, and ammonia, nitrate, and nitrite, concentrations. A method was developed for measuring cellular nutrient reservoirs in laboratory cultures of marine phytoplankton....

A Bayesian approach to marine spatial planning

Creator:: Erhardt, Morgan William
Abstract:: The marine ecosystem provides a broad spectrum of services for a wide array of user groups. Such broad use of marine resources often results in use conflicts between ecosystem elements and human interests. To help mitigate these conflicts, the Bayesian Analysis for Spatial Siting (BASS) tool was developed to incorporate...

Absolute water velocity profiles from glider-mounted acoustic doppler current profilers

Creator:: Ordonez, Christopher Edward
Abstract:: This paper details a method to compute absolute water velocity profiles from glider-based acoustic Doppler current profiler (ADCP) measurements based on the "shear method" developed for lowered ADCPs. The instrument is a 614-kHz Teledyne RDI ADCP integrated into the body of a Teledyne Webb Research Slocum Glider. Shear is calculated...

Implementation of a gross anatomical maturity key for the study of spawning phenology and geography of Pacific cod (Gadus macrocephalus)

Creator:: Neidetcher, Sandra
Abstract:: Pacific cod (Gadus macrocephalus) is an important species, both economically and ecologically in the Bering Sea and Aleutian Islands (BSAI). However, little is known about its spawning dynamics. To address this knowledge gap, I developed a gross anatomical maturity key for Pacific cod to assess temporal and spatial patterns of...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Investigation of twelve earthquakes off the Oregon and northern California coasts

Creator:: Rinehart, Verill Joanne
Abstract:: Twelve earthquakes off the Oregon and Northern California coasts were used in this research to study whether faulting associated with these quakes was of the San Andreas type as observed in California. The first motions of the incident P and S waves recorded at various seismic stations in the Pacific...

The distribution and partitioning of dissolved organic matter off the Oregon Coast : a first look

Creator:: Hill, Jon K.
Abstract:: The purpose of this thesis is to provide a first look at the spatial and temporal distributions of dissolved organic material (DOM) off the Oregon coast of North America. While this paper is not a comprehensive examination of these distributions, several patterns are identified as promising candidates for continued research....

Substrate capture, uptake, and utilization of some amino acids by starved cells of a psychrophilic marine vibrio

Creator:: Glick, Melissa Ann
Abstract:: Starved cells of Ant-300, a psychrophilic marine Vibrio, maintained binding and transport systems for glutamic acid, arginine, proline, and leucine. The uptake of these amino acids was inhibited by the uncoupler 2,4-dinitrophenol indicating that an energized membrane was necessary for binding and was maintined in starved cells. The levels of...
