Shear wave attenuation in unconsolidated laboratory sediments

Creator:: Brunson, Burlie A.
Abstract:: Shear wave attenuation measurements were made using ceramic bimorph transducers to excite transverse vibrations in a cylindrical column of unconsolidated sediment. Three different water-saturated sediments were used in an attempt to determine the effects of grain shape and sorting on the frequency dependence of attenuation. The mean grain size of...

An analysis of one year of surface layer meteorological data from the Arctic pack ice

Creator:: Baumann, Richard James
Abstract:: The thesis describes the properties of surface wind and air temperature time series recorded at three locations on the pack ice of the Beaufort Sea. Time series consisting of sequential one-half hourly means were constructed for a period of approximately a year. A diurnal fluctuation in air temperature is found...

Foraminiferal trends of the central Oregon shelf

Creator:: Boettcher, Richard Scott
Abstract:: Sediments of a portion of the central Oregon shelf between 17 and 339 m have been examined for modern foraminifera. Eighty-three samples were collected from 33 stations along three traverses located between 43° 16'N and 43° 50'N. One hundred fifty-five benthic and nine planktonic species are recognized. Fifty-six benthic species...

Long wavelength gravity anomalies and implications concerning a descending lithospheric slab in the Pacific Northwest

Creator:: MacFarlane, William Thomas
Abstract:: The thermal regime of a postulated descending lithospheric slab is calculated. The gravity anomaly associated with such a structure is large in amplitude and long in wavelengh. Observed free-air gravity anomalies in the Pacific Northwest do not indicate a gravitational effect due to a descending slab. Two hypothetical compensation models...

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...

Non-biological uptake of zinc-65 from a marine algal nutrient medium

Creator:: Tomlinson, Richard Douglas
Abstract:: The nature and magnitude of experimental errors due to ⁶⁵Zn adsorption by inorganic surfaces was examined in a laboratory system designed to measure ⁶⁵Zn uptake by marine phytoplankton. In the pH range, 6.3±.1 to 7.5±.1, a precipitate formed in the algal nutrient medium selected for the system. To this seawater-base...

On coastal trapped waves at low latitudes in a stratified ocean

Creator:: Romea, Richard Dennis
Abstract:: The response on the continental shelf of a baroclinic ocean to driving by an alongshore coastal wind stress and by barotropic and baroclinic wind forced interior motions is studied as a function of latitude. The relative excitation of continental shelf waves and internal Kelvin waves is studied. The response of...

A systems approach to pelagic ecosystem dynamics in an estuarine environment

Creator:: Iverson, Richard L.
Abstract:: Phytoplankton dynamics in Auke Bay, Alaska, were studied during summer, 1969. Nitrate, chlorophyll a, particulate organic carbon, phytoplankton and zooplankton species composition and hydrographic and meteorological data were collected and analyzed. Nitrate input into Auke Bay through freshwater runoff was negligible. A bloom of Thalassiosira aestivalis formed the spring bloom...
