Marine geology of the continental margin off southern Oregon

Creator:: Spigai, Joseph John
Abstract:: The continental margin off southern Oregon, which includes the shelf and slope from Cape Blanco to the Oregon-California border, exhibits a distinctive marginal-plateau structural pattern which divides the margin into the continental shelf, the upper continental slope and its associated benches, and the lower continental slope. Lutum transport and deposition...

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...

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...

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...

The distribution of hyperiid amphipods off the Oregon coast

Creator:: Van Arsdale, Harriet Ann
Abstract:: Hyperiid amphipods from one-meter plankton net collections made over a two year period at stations 15, 25, 50, and 65 nautical miles off Newport, Oregon, were examined. Nineteen species were identified. The occurrence of some species off Oregon significantly extended the known geographic ranges. To my knowledge Scina crassicornis burmudensis...

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...
