Above and Below : Oregon Coastal Phytoplankton Bloom Dynamics from Sea and Space

Creator:: McKibben, S. Morgaine
Abstract:: Phytoplankton are a sentinel class of organisms in the marine environment. Through their photosynthetic activity in sunlit waters worldwide, phytoplankton shape the health and productivity of marine ecosystems and impact the global climate. In this work a range of ocean sensing technologies (via ships, surf zone sampling, moorings, gliders, and...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Occurrence, transmission, and properties of strains of cucumber mosaic virus that are seed-transmitted in Phaseolus vulgaris

Creator:: Davis, Robert Francis
Abstract:: A survey of major bean (Phaseolus vulgaris) breeding programs and seed producing areas in Idaho, Washington, and Oregon was conducted to determine the occurrence of cucumber mosaic virus (CMV), recently reported to be seedborne in beans. Some 259 plants, sampled from breeding lines of diverse germplasm, were found by enzyme-linked...

An experimental/analytical investigation of buoyant jets in shallow water

Creator:: Hsiao, Entsung
Abstract:: This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the...

An experimental/analytical investigation of deep submerged multiple buoyant jets

Creator:: Kannberg, Landis Dee
Abstract:: The results of an experimental and analytical study of deep submerged multiple-port thermal discharges are presented. The experimental results include the measured downstream thermal dilution, width, and centerline trajectory of the buoyant thermal plume from multiport jets. Independent parameters for which measurements were obtained include port spacing, discharge Froude Number,...

Elevated temperature and the production of juvenile Chinook salmon (Oncorhynchus tshawytscha) in a model stream

Creator:: Bisson, Peter Andre
Abstract:: Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...

An experimental investigation of drilling mud discharged into a flowing stratified environment

Creator:: Mohebbi, Behrooz
Abstract:: An experimental study of the short-term fate of a drilling mud discharged into a flowing stratified environment was conducted to determine its dilution and settling characteristics. The drilling mud used in this test had a specific gravity of 1.184 and a composition of 12 percent by weight high-gravity solids (BaSO₄)...

Transient heat and mass transfer in soils in the vicinity of heated porous pipes

Creator:: Slegel, David L.
Abstract:: Differential equations governing the combined heat and mass transfer in soils are developed. Transient heat, liquid and vapor transfer with phase change is considered. The liquid transfer is treated as a function of the hydraulic conductivity and the gradient of suction potential. The suction potential is considered a function of...

An experimental investigation of the thermomechanics of pipe flow of magnetic fluids in response to heating and applied magnetic fields

Creator:: Hamedani, Hooshyar M.
Abstract:: An experimental investigation was carried out to determine the thermodynamics and fluid mechanics of the pipe flow of magnetic fluids. A water-based magnetic fluid was synthesized in the laboratory and its relative viscosity and magnetic properties were determined as a function of temperature. A "thermomagnetic pump" was built and tested...
