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...

Distribution of recent foraminifera in relation to estuarine hydrography, Yaquina Bay, Oregon

Creator:: Manske, Douglas Charles
Abstract:: The foraminiferal population of Yaquina Bay was investigated to attempt a correlation of seasonal changes in the hydrography with observed changes in the faunal distribution patterns. The results are based on data from two spatial surveys conducted in July 1966, and late February and March, 1967. The hydrography of Yaquina...

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...

Sea level, winds, and upwelling along the Oregon coast

Creator:: Panshin, Daniel Alexis
Abstract:: The relationship between sea level and wind stress in a region of known upwelling was studied for an eleven-month period during 1933-34. Sea level data, obtained from observations taken by the Coast and Geodetic Survey, were processed to remove astronomic tidal constituents and inverted barometer effect. Regression analysis was used...

Geostrophic and Sverdrup transports as indices of flow in the Gulf of Alaska

Creator:: Favorite, F.
Abstract:: The intensification of cyclonic winds in the Gulf of Alaska during winter belies the relatively constant geostrophic circulation as being indicative of actual flow. In the absence of direct current measurements, effects of various meteorological phenomena have been eliminated from monthly mean sea level measurements over the decade 1950 to...

Sea-air CO₂ flux variability on the northeast Pacific continental margin

Creator:: Evans, Wiley
Abstract:: Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...

Physical parameters as tracers of Columbia River water

Creator:: Evans, Richard H.
Abstract:: Hydrographic and bathythermograph data taken off the Oregon coast during a two week period in August of 1969 were analyzed to determine if heat content and mixed layer depth may be used as indicators of Columbia River plume water. Heat content was found to be a poor indicator of plume...
