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...

Creator:: Enfield, David B.
Abstract:: Moored instrument records, drogue displacements, and hydrographic observations are used in describing the coastal currents and upwelling off Peru. The data were obtained over the continental shelf near 15°S. during a two week study in late March and early April of 1969. First order statistics and graphical representations of current...

Creator:: Eklund, William Alan
Abstract:: Examination of polished sections of manganese micronodules from metalliferous sediments from the Bauer Deep reveals sequences of ferromanganese deposition which are consistent for micronodules from a single sediment sample and imply a common depositional history for members of such assemblages. The relatively simple 'stratigraphy' of manganese micronodules, as compared to...

Creator:: Bowline, Cynthia Marie
Abstract:: The energy levels of internal waves observed during the Arctic Internal Wave Experiment (AIWEX), conducted from the drifting pack ice in the Beaufort Sea, increased as the speed of the ice drift increased. The possibility of these waves being generated by moving pack ice with a corrugated under-side is explored...

Creator:: Hubbard, Dale A.
Abstract:: Solid phases that form under the influence of changing environmental conditions often record such changes in their chemical composition. Quantification of these compositional variations is invaluable in reconstructing paleoenvironmental changes. Laser ablation, employed as a solid sample introduction system, offers fine spatial resolution (50 - 250 [mu]m) for spectroscopic analysis...

Creator:: McKnight, William Ross
Abstract:: Ninety-five oriented samples were obtained from nine Recent Cascade lava flows in Oregon. Directions and intensities of remanent magnetization were measured on a spinner magnetometer which measures directions of magnetization to within 1.2° s.d. Angle measurements were plotted graphically using an equal area projection. Mean directions and statistics were calculated...

Creator:: Keene, Donald Frederick
Abstract:: The nearshore zone at Newport, Oregon was studied during the period September, 1968 to August, 1969. Particular emphasis was placed on those physical factors affecting the distribution of pulp mill wastes discharged within the study area (referred to as Yaquina Bight in this thesis). Temperatures and seawater samples were obtained...

Creator:: Fritz, Cara E.
Abstract:: A year-long field study was undertaken to investigate the influence of a number of physical and biological factors, specifically temperature, organic carbon content, and shrimp population dynamics on sediment reworking rates by the ghost shrimp Neotrypaea calforniensis. Because of its role as a structuring agent in estuaries along the West...

Creator:: Osmer, Stephen Robert
Abstract:: Sea level and the alongshore component of wind stress data at seven locations on the Pacific coast of Canada and the United States were analyzed. The effective data period was from August 1, 1973 to September 9, 1975. The seven locations were Tofino, British Columbia; Neah Bay and Toke Point,...

Creator:: Detweiler, John Henry
Abstract:: The data recorded between March 3, 1969, and October 31, 1969, by a wind gauge installed at the South Jetty, Newport, Oregon, were analyzed. The components of each observation were treated as if they were an independent, normal, bivariate distribution and standard statistical procedures were applied. It was found that...

Creator:: Dahm, Clifford N.
Abstract:: During the GEOSECS cruise of the R/V KNORR, July 1972-April 1973, a very complete and high quality nutrient data set was acquired for the Atlantic Ocean. One hundred and twenty-one hydrographic stations were occupied throughout the Atlantic providing an internally consistent picture of the nutrient dynamics for this ocean. The...

Creator:: Markham, John Charles
Abstract:: During the six-month period of July through December, 1966, a study of animals inhabiting laminarian holdfasts in Yaquina Bay, Oregon, was carried out to determine what animals live in this habitat and to gain some idea of the factors which influence their presence and distribution. This study deals with yet...

Creator:: Huyer, Adriana, 1945-
Abstract:: This thesis demonstrates that at low frequencies (periods longer than 2.5 days) local currents off the coast of Oregon are closely related to the wind. Wind and current observations made during August and September 1969 are described and compared to demonstrate that a relationship exists; the physics of the interaction...
