Computer analysis of the surface current field off Oregon based on drift bottle data

Creator:: Lung, Hu Ernest
Abstract:: The fall-winter surface current field off Oregon was determined by analysis of ten years of drift bottle data. Computer programs were developed for generating bottle tracks on a numerical grid, for interpolating bottle velocity components to fill void grid points and for smoothing irregularities in the velocity fields. Charts are...

Plankton and nutrient ecology of the Columbia River estuary

Creator:: Haertel, Lois Steben
Abstract:: Monthly samples of nutrients, phytoplankton and zooplankton were taken in the Columbia River estuary over a period of 16 months in order to determine distribution with season and salinity, and interrelationships between plankton and nutrients. Nitrate and phosphate levels in the river water entering the estuary are high in the...

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...

Distribution of Euphausiacea and Copepoda off Oregon in relation to oceanographic conditions

Creator:: Hebard, James Frank
Abstract:: Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...

Late quaternary oceanic circulation along the Pacific Coast of South America

Creator:: Molina-Cruz, Adolfo
Abstract:: The distribution patterns of quartz and opal contents and the distribution patterns of radiolarian assemblages, in the sediments of the southeastern Pacific, are largely controlled by both the surface winds and the mixed-layer oceanic circulation. The distribution pattern of quartz is related to eolian and ice-rafted transport, as well as...

Magnetic and gravity interpretation of Yaloc-69 data from the Cocos plate area

Creator:: Lu, Richard Shih-Ming
Abstract:: Magnetic, gravity and bathymetry data were collected on an extended cruise of the R/V Yaquina in 1969. The last set of data was obtained from those track lines leaving the Panama Basin. The area covered is mainly the Cocos plate (Molnar and Sykes, 1969). The data is analyzed and compared...

Mathematical approaches to the physics of mesoscale oceanography

Creator:: Early, Jeffrey J.
Abstract:: The long-term evolution of Gaussian eddies is studied in an equivalent barotropic model using both linear and nonlinear quasi-geostrophic theory in an attempt to understand westward propagating satellite altimetry tracked mesoscale eddies. By examining both individual eddies and a large basin seeded with eddies, it is shown that long term...

The effect of the land breeze on the mesoscale wind field off the Oregon coast

Creator:: Poole, Stephen Lynn
Abstract:: Two land breeze events occurred off the Oregon coast on the nights of April 19th and 20th, 1973. An array of four moored toroid buoys and one land station recorded the effect of the land breeze event on the surface mesoscale wind and temperature fields. The land breezes may have...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...
