Effects of bark debris on benthic macro-fauna of Yaquina Bay, Oregon

Creator:: Walker, John David
Abstract:: Benthic samples were collected during the summer, winter and spring seasons from upper Yaquina Estuary, a region used by Georgia- Pacific Corporation for log dumping and storage. Samples came from an active log dump and storage areas as well as areas not associated with log handling activity. The samples were...

The distribution of epiphytic diatoms in Yaquina Estuary, Oregon

Creator:: Main, Stephen Paul
Abstract:: Epiphytic diatom assemblages in the intertidal zone of Yaquina Bay and estuary were obtained from the following host macrophytes: Zostera marina, Fucus evanescens, and species of Enteromorpha, Polysiphonia, and Ulva. Samples were collected in September 1970 and in January and May 1971 from seven stations approximately evenly spaced between the...

Benthal sulfide release in aquatic systems

Creator:: Bella, David A., Oregon State University. Water Resources Research Institute, and United States. Office of Water Resources Research
Abstract:: The purpose of this study was to better understand benthic systems with emphasis given to the sulfur cycle. The primary focus was directed toward the release of free sulfide from benthic systems.

Factors that influence sulfide production in an estuarine environment

Creator:: Peterson, Paul Edward
Abstract:: Core samples from five sites in the Yaquina and Coos Estuary were assayed for vertical distribution of total sulfides, percent volatile solids, redox potential, particle size, total aerobic and sulfate reducing bacteria. Higher total sulfide levels were found at sites having more than four percent volatile solids, redox potential below...

Some aspects of the sulfur cycle in tidal flat areas, and their impact on estuarine water quality

Creator:: Ramm, Alan Edmund
Abstract:: A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...

Harbor dredging and benthic infauna : a case study

Creator:: Parr, Robert Alexander
Abstract:: This study of the immediate, localized effects of a small dredging operation on the benthic invertebrate community in the shipping channel of Coos Bay, Oregon, was designed: 1) to measure the extent of the physical removal of benthic macro- and meiofauna by hopper dredging; 2) to record the subsequent benthic...

Physical hydrography and nutrient nitrogen budget of Auke Bay, Alaska

Creator:: Kirk, Deborah Kathleen
Abstract:: Physical sources of nutrient nitrogen for the Auke Bay, Alaska estuarine ecosystem were investigated. These sources included vertical dispersion, advection, and fresh water sources. Hydrographic circulation patterns for the bay, and a nutrient budget for the surface mixed layer were developed. Measurements of temperature, salinity, currents, wind velocity, rainfall and...

Salinity and temperature interactions and their relationship to the microbiology of the estuarine environment

Creator:: Morita, Richard Y., Jones, Larry P., Griffiths, Robert P., and Staley, Thomas E.
Abstract:: An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...

Ecological studies in radioactivity in the Columbia River Estuary and adjacent Pacific Ocean : progress report 1 July 1972 through 31 March 1974

Creator:: Cutshall, N. H., Carey, Andrew G., Holton, Robert L., Pearcy, William G., Renfro, William C., and McMechan, Karla J.
Abstract:: This report presents progress accomplished during the 20-month period from 1 July 1972 through 31 March 1974 as part of the program "Ecological Studies of Radioactivity in the Columbia River Estuary and Adjacent Pacific Ocean". This program is a continuing study supported by the Division of Biomedical and Environmental Research...
