Biostratigraphy and paleoecology of the Coaledo and Bastendorff Formations, southwestern Oregon

Creator:: Rooth, Guy Harlan
Abstract:: Fossil foraminifers from the Coaledo and Bastendorff Formations near Coos Bay in southwestern Oregon were studied in an attempt to determine the age and environment of deposition. Fresh unweathered samples were collected from sea cliffs between Cape Arago and Charleston, Oregon. A large late Eocene delta is preserved in the...

Species specific phytoplankton production rates during a spring diatom bloom in Yaquina Bay, Oregon

Creator:: McMurray, Gregory R., 1925-
Abstract:: A simplified autoradiographic method for estimating species-specific phytoplankton production rates in mixed natural communities was evaluated in the laboratory and employed in the field. Laboratory experiments were designed to test the reliability and variability of the simplified method. Assays of ¹⁴C uptake by liquid scintillation spectrometry were used to evaluate...

Effects of micro-nutrients and major nutrients on the growth and species composition of natural phytoplankton populations

Creator:: Frey, Bruce E.
Abstract:: Large-volume (20-liter) bioassays were carried out in order to assess the effects of major nutrients and micro-nutrients on natural phytoplankton populations in water collected from a site close to the mouth of Yaquina Bay, Oregon. Seven long-term experiments were conducted during the years 1975-1976. A stripping technique employing activated carbon...

Population structure of the intertidal shore crab Hemigrapsus oregonensis (Brachyura, Grapsidae) in Yaquina Bay, a central Oregon coast estuary

Creator:: Batie, Robert Edward
Abstract:: The Hemigrapsus oregonensis population at Coquille Point in the Yaquina Bay Estuary on the Central Oregon Coast was studied from April, 1972 through May, 1973. The population was found to be vertically stratified from the 1 ft level to the 5 ft level. Population densities were found to be most...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Sublethal effects of estuarine carbaryl applications on juvenile English sole (Pleuronectes vetulus)

Creator:: Pozarycki, Scott V.
Abstract:: The pesticide carbaryl is applied annually to tidelands in Willapa Bay and Grays Harbor, WA to control populations of burrowing shrimp which modify sediments making the habitat unsuitable for oyster culture. Fish trapped on sprayed mudflats are often killed, but little is known about effects on fish present in subtidal...

Ecology of benthic microalgae of estuarine intertidal sediments

Creator:: Riznyk, Raymond Zenon
Abstract:: The benthic microalgae of sediments of the two tidal flats in Yaquina Bay, Oregon were investigated to determine the environmental factors limiting the abundance and the horizontal and vertical distribution of these organisms. The Southbeach tidal flat which is under the marine realm of deposition consists of fine to medium...

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...

Sediments of Yaquina Bay, Oregon

Creator:: Kulm, LaVerne D., 1936-
Abstract:: Three realms of deposition, Marine, Fluviatile, and Marine- Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of sediment texture and mineralogy. The Marine Realm extends 1.5 miles into the entrance of the estuary and is typified by normal marine salinity and vigorous tidal action. Sediments of this realm...
