Creator:: Farreras, Salvador F.
Abstract:: The one-dimensional numerical model developed by Carl R. Goodwin is applied to the Siuslaw estuary. Vertical displacement, horizontal velocity and flow of the water as a function of time and distance from the mouth given by the model are compared with field observations taken under different water mixing conditions in...

Creator:: Wilson, Stephanie Lynn
Abstract:: The benthic amphipod Corophium salmonis was sampled seasonally from two sites (Desdemona Sands and Grays Bay) in the Columbia River estuary. Populations of C. salmonis at both sites were found to have a two generation per year life cycle, a spring generation and a fall generation. The spring generation juveniles...

Creator:: Morgan, Stacey Rose
Abstract:: The Columbia River Estuary was sampled during high (May-June), intermediate (July), and low (September-October) river flow seasons to further define the role of the ETM with respect to its effect on primary biomass and production, and to discover how this effect changes in space and time. Strong ETMs were determined...

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...

Creator:: Hanson, Peter James
Abstract:: In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...

Creator:: Hammann, Mark Gregory
Abstract:: The migrations, distribution, and feeding of American shad, Alosa sapidissima (Wilson), were studied from February 1980 through January 1981 in the Columbia River Estuary, an important rearing zone for young-of-the-year shad. Sampling was performed with purse seine, beach seine, and otter trawl. Adult shad and large numbers of juveniles from...
